An even bigger abortion and even more illegal. with a plug on one end goes into the multiway power strip the computer's plugged into. The other end feeds to a connector block I stuck inside the fusebox, connecting straight to the lighting circuits (two of them), instead of them running off the fuses. Non trivial to get into the meter box the way its done here. You built your own house, what did you do wrong? I didn't do anything wrong. All the wiring goes down the holes in the concrete blocks. Take the cover off the fusebox and access the relevant bits. and the LEDs last much longer now. I'm mostly still using long tube fluoros. Most of mine wore out. None of mine have, and they are all 45 years old now, still in perfect condition. Not the tubes themselves surely? Sure, but they last 20+ years and cost peanuts to replace. MUCH less than leds do. Haven't bought those old inefficient flickery things for years. They are in fact more efficient than anything but leds and arent flickery at all They are to my eyes. Your problem, I don't have that problem. I find most car LEDs flickery too. Ditto. Odd you find one flickery and not the other, I don't find any flickery. That's what I meant by the ditto. I said I found most car LEDs flickery, you said ditto, meaning you also find the same things flickery as me - most car LEDs. what about CRT monitors with low Hz? Not flickery either. You must have slow eyes. and MUCH cheaper per decade than leds too. LEDs are cheaper per decade Nope. due to halving the power consumption. The lights arent on enough to pay for themselves that way. If they aren't on much, the LEDs will also last longer. LEDs don't die due to time on, its only the other technologys that do that. They are quoted as hours of usage, usually 100,000 if not in a confined unit. I am planning to have a very long strip of leds for the main kitchen benches but haven't gotten around to doing that yet. I use these, they connect together: www.ebay.co.uk/itm/272393435045 Yeah, saved that the first time you mentioned them. Not keen on your previous comment about them dying tho. No, those don't die. OK, but they don't ship here for a sensible price and I'm not keen on the aesthetics either. Silly making them look like long tube fluoros, they should be simple say 10mm square cross section. I'd get that result with the flexible strips of leds glued into a 10mm U channel of aluminium or stainless steel. Could do, but these are quicker for me to put up. They wouldn't be because you need at least two screws per segment. One. The ones I've had die are the GU10 spots with the LEDs too close together and they run too hot. And it would be more convenient to get a very long length of aluminium U section about 10mm across about 3.5m long and have those led flexible strips in those, glued in. But I'm not keen on the life people currently get with those or the price of the ones with only 5 year warrantys. The ones I linked to are so easy to put up. Not as easy as my approach, just two screws into the bottom of the roof beams which have the flange inside the ceiling, per 3.5m length of U section. The modular approach of yours wouldn't work anything like as well because the roof beams are on 4' centers and I'd need two screws for each 4' module and 3 of those in each row, two rows. Not clear if its bright enough either, the ceiling is 8'8". Might need two rows in each row. Trivially easy to have the U channel say 15mm wide and have two rows of the flexible led strips glued into each channel if that is needed to be bright enough. Wouldn't need the modular approach or anything like the same total cost either. I just use one clip per 2 foot strip screwed into the ceiling, Makes no sense to have 2 foot strips in my situation where I need the strips to be 20' long in the kitchen and 40' long in the main room. In my kitchen I just plugged several together. And my ceiling is drop in 4' wide polyfoam paper faced panels. Ah, cheap ****. Cant screw into those every 2'. Must be a joist every 2 feet. Makes a lot more sense to have just 2 screws to hold the 20' of channel onto the bottom of the I beams that the 4' paper faced poly foam panels drop into. don't have to be central, they plug into each other and support each other. 20' and 40' channel works better. I'd say the best thing would be what I linked to, but longer versions, must be some somewhere. Or you can get LED tubes that fit into existing fluor fittings, just take the ballast out. -- Change is inevitable, except from a vending machine. |

Thanks for your input. The device you show isn't actually mains powered i.e. you have the problem of supplying 18V DC. This additional circuit makes it a much more expensive solution than the one I'm proposing. It also explains its lack of size and beefiness. It also explains why there is no need for a metal cover.

I'd say the best thing would be what I linked to, but longer versions, must be some somewhere. Even 4' ones would still be a lot more farting around mounting them that a single 20' piece of U channel with just a couple of screws into the bottom flange of the galvanised steel I beams which are at 4' centers. Or you can get LED tubes that fit into existing fluor fittings, just take the ballast out. The fluoros arent where the 20' strip of led would be and two 20' led strips in a 10mm U channel over each of the long benches would look vastly better. Much better than your leds too, they pretend to be fluoros. Stupid approach. The new technology should be done the best way it can be, not pretending to be the previous technology. |

An even bigger abortion and even more illegal. with a plug on one end goes into the multiway power strip the computer's plugged into. The other end feeds to a connector block I stuck inside the fusebox, connecting straight to the lighting circuits (two of them), instead of them running off the fuses. Non trivial to get into the meter box the way its done here. You built your own house, what did you do wrong? I didn't do anything wrong. All the wiring goes down the holes in the concrete blocks. Take the cover off the fusebox and access the relevant bits. There is no cover, it has a big metal door and the problem isnt access to the relevant bits, its how to get that cable into the big metal box its in and still be legal, because currently the meter reader opens that big metal door every time he reads the meter. The box in on the outside wall of the house, in the back yard and is read by the meter reader every 3 months. The 3'x3' big metal box is set into the wall, it is bolted into a 4" deep hole in the wall which has 4" concrete blocks at the back of the box in the 8" thick block wall there. The cables all come in thru the top of the meter box which has its top with 1 course of 8" block above it. Ah, so your fuses are outside. Odd way to do it. Nope, that allows the meter to be read any time the meter reader wants to do that and doesn't need anyone to let them into the house. So why can't you tap into the wire once it's in the house? There isnt just one wire for all the lights. There isnt even just one light circuit either. You can join onto it anywhere there's a light fixture, and simply disconnect that fuse. There isnt just one fuse. and the LEDs last much longer now. I'm mostly still using long tube fluoros. Most of mine wore out. None of mine have, and they are all 45 years old now, still in perfect condition. Not the tubes themselves surely? Sure, but they last 20+ years and cost peanuts to replace. MUCH less than leds do. Haven't bought those old inefficient flickery things for years. They are in fact more efficient than anything but leds and arent flickery at all They are to my eyes. Your problem, I don't have that problem. I find most car LEDs flickery too. Ditto. Odd you find one flickery and not the other, I don't find any flickery. That's what I meant by the ditto. I said I found most car LEDs flickery, you said ditto, Yes. meaning you also find the same things flickery as me - most car LEDs. Nope, meaning that my comment on not finding fluours flickery applied to the car leds too. Ah, you were dittoing your own comment. Yep. Silly. What's how the ditto is normally used. what about CRT monitors with low Hz? Not flickery either. You must have slow eyes. Normal eyes. Most don't find fluoros flickery or car leds either. You are a freak as, usual. Many do, There are plenty of freaks. Always have been, always will be. Some are freaky enough to run around with no clothes on in the middle of winter. easy to google for people moaning about car lights. FAR more don't. Having something that works faster makes you better. Nope, just a freak. Pigeons have even better sight than us and can't watch television. Just as well, TV progs for pigeons would be a tad boring. and MUCH cheaper per decade than leds too. LEDs are cheaper per decade Nope. due to halving the power consumption. The lights arent on enough to pay for themselves that way. If they aren't on much, the LEDs will also last longer. LEDs don't die due to time on, its only the other technologys that do that. They are quoted as hours of usage, usually 100,000 if not in a confined unit. That number is clearly straight from someone's arse and isnt measured. It's from the manufacturer of the LED. From someone who works for that manufacturer's arse. And if it is true, that's 12 years so the ones you use are lousy value compared with long tube fluoros which usually last me about 20 years and cost much less. 12 years on 24 hours a day, which yours aren't. You have no idea about mine. And how much power would you use over 100,000 hours? I am planning to have a very long strip of leds for the main kitchen benches but haven't gotten around to doing that yet. I use these, they connect together: www.ebay.co.uk/itm/272393435045 Yeah, saved that the first time you mentioned them. Not keen on your previous comment about them dying tho. No, those don't die. OK, but they don't ship here for a sensible price and I'm not keen on the aesthetics either. Silly making them look like long tube fluoros, they should be simple say 10mm square cross section. I'd get that result with the flexible strips of leds glued into a 10mm U channel of aluminium or stainless steel. Could do, but these are quicker for me to put up. They wouldn't be because you need at least two screws per segment. One. Still much more than with my approach. Screws are easy to put up. Not when there is nothing to screw them into. The ones I've had die are the GU10 spots with the LEDs too close together and they run too hot. And it would be more convenient to get a very long length of aluminium U section about 10mm across about 3.5m long and have those led flexible strips in those, glued in. But I'm not keen on the life people currently get with those or the price of the ones with only 5 year warrantys. The ones I linked to are so easy to put up. Not as easy as my approach, just two screws into the bottom of the roof beams which have the flange inside the ceiling, per 3.5m length of U section. The modular approach of yours wouldn't work anything like as well because the roof beams are on 4' centers and I'd need two screws for each 4' module and 3 of those in each row, two rows. Not clear if its bright enough either, the ceiling is 8'8". Might need two rows in each row. Trivially easy to have the U channel say 15mm wide and have two rows of the flexible led strips glued into each channel if that is needed to be bright enough. Wouldn't need the modular approach or anything like the same total cost either. I just use one clip per 2 foot strip screwed into the ceiling, Makes no sense to have 2 foot strips in my situation where I need the strips to be 20' long in the kitchen and 40' long in the main room. In my kitchen I just plugged several together. Sure, but there isnt any way to have one screw per 2' strip. Yes there is. No there isnt. Clips (one screw each) 2 feet apart, in about the centre of each strip. Nothing to screw it into. And my ceiling is drop in 4' wide polyfoam paper faced panels. Ah, cheap ****. Nothing cheap about it and it isnt **** either, each panel is completely rigid, no sagging at all. But you can't screw anything into it, Wrong, as always. The bottom of the I beams are fine. rather useless. Wrong, as always. Leaves conventional ceilings for dead. That's why I hate plasterboard walls, not as easy putting up pictures as on wood walls. I don't bother with pictures. Cant screw into those every 2'. Must be a joist every 2 feet. Nope, every 4' as I said. These are galvanised steel I beams with one of the top flanges missing. Makes a lot more sense to have just 2 screws to hold the 20' of channel onto the bottom of the I beams that the 4' paper faced poly foam panels drop into. don't have to be central, they plug into each other and support each other. 20' and 40' channel works better. I'd say the best thing would be what I linked to, but longer versions, must be some somewhere. Even 4' ones would still be a lot more farting around mounting them that a single 20' piece of U channel with just a couple of screws into the bottom flange of the galvanised steel I beams which are at 4' centers. Your way sounds complicated to me. Because you have never had a clue. You have extra stuff to set up. Nope, just two screws per 20' piece of channel, leaves yours for dead. I just use the supplied clips and connectors. The strips of leds come with connectors and all you have to do is glue it into the channel. Or you can get LED tubes that fit into existing fluor fittings, just take the ballast out. The fluoros arent where the 20' strip of led would be and two 20' led strips in a 10mm U channel over each of the long benches would look vastly better. Much better than your leds too, they pretend to be fluoros. Stupid approach. The new technology should be done the best way it can be, not pretending to be the previous technology. LEDs are best in strips like mine, then they don't overheat. The flexible strips of LEDs in channel would have exactly the same number of leds per foot as yours and have an aluminium channel behind them so will dissipate heat even better than yours which have plastic behind them and are vastly better to mount, just 2 screws per 20' strip. And no connectors between each strip to fail either. |

Having something that works faster makes you better. Nope, just a freak. Faster is ALWAYS better. It clearly isnt when you see fluoros, TVs and car leds flickering and whine about that where google can see that, stupid. Pigeons have even better sight than us and can't watch television. Just as well, TV progs for pigeons would be a tad boring. Rubbish. TV showing the sort of rubbish pigeons are into would be very boring indeed, stupid. and MUCH cheaper per decade than leds too. LEDs are cheaper per decade Nope. due to halving the power consumption. The lights arent on enough to pay for themselves that way. If they aren't on much, the LEDs will also last longer. LEDs don't die due to time on, its only the other technologys that do that. They are quoted as hours of usage, usually 100,000 if not in a confined unit. That number is clearly straight from someone's arse and isnt measured. It's from the manufacturer of the LED. From someone who works for that manufacturer's arse. It's a specification. If they lied, they'd lose business. Pigs arse they would given that it would take years to see they lied. And if it is true, that's 12 years so the ones you use are lousy value compared with long tube fluoros which usually last me about 20 years and cost much less. 12 years on 24 hours a day, which yours aren't. You have no idea about mine. You've already told me. Like hell I did on that question. And how much power would you use over 100,000 hours? Well? Work it out for yourself. I am planning to have a very long strip of leds for the main kitchen benches but haven't gotten around to doing that yet. I use these, they connect together: www.ebay.co.uk/itm/272393435045 Yeah, saved that the first time you mentioned them. Not keen on your previous comment about them dying tho. No, those don't die. OK, but they don't ship here for a sensible price and I'm not keen on the aesthetics either. Silly making them look like long tube fluoros, they should be simple say 10mm square cross section. I'd get that result with the flexible strips of leds glued into a 10mm U channel of aluminium or stainless steel. Could do, but these are quicker for me to put up. They wouldn't be because you need at least two screws per segment. One. Still much more than with my approach. Screws are easy to put up. Not when there is nothing to screw them into. More fol you for having a **** ceiling. Leaves yours for dead. The ones I've had die are the GU10 spots with the LEDs too close together and they run too hot. And it would be more convenient to get a very long length of aluminium U section about 10mm across about 3.5m long and have those led flexible strips in those, glued in. But I'm not keen on the life people currently get with those or the price of the ones with only 5 year warrantys. The ones I linked to are so easy to put up. Not as easy as my approach, just two screws into the bottom of the roof beams which have the flange inside the ceiling, per 3.5m length of U section. The modular approach of yours wouldn't work anything like as well because the roof beams are on 4' centers and I'd need two screws for each 4' module and 3 of those in each row, two rows. Not clear if its bright enough either, the ceiling is 8'8". Might need two rows in each row. Trivially easy to have the U channel say 15mm wide and have two rows of the flexible led strips glued into each channel if that is needed to be bright enough. Wouldn't need the modular approach or anything like the same total cost either. I just use one clip per 2 foot strip screwed into the ceiling, Makes no sense to have 2 foot strips in my situation where I need the strips to be 20' long in the kitchen and 40' long in the main room. In my kitchen I just plugged several together. Sure, but there isnt any way to have one screw per 2' strip. Yes there is. No there isnt. Yes, one screw per clip, one clip per 2 foot strip of LEDs. And nothing to screw it into with half of them. Clips (one screw each) 2 feet apart, in about the centre of each strip. Nothing to screw it into. My ceiling accepts screws. Wood cladding or plasterboard takes screws. Only a terminal ****wit screws things into plasterboard. And my ceiling is drop in 4' wide polyfoam paper faced panels. Ah, cheap ****. Nothing cheap about it and it isnt **** either, each panel is completely rigid, no sagging at all. But you can't screw anything into it, Wrong, as always. The bottom of the I beams are fine. But I can screw anywhere. No you can't you snapped your dick off years ago. That's why everyone ****es themselves laughing when you go streaking. rather useless. Wrong, as always. Leaves conventional ceilings for dead. But I can screw anywhere. No you can't you snapped your dick off years ago. That's why everyone ****es themselves laughing when you go streaking. That's why I hate plasterboard walls, not as easy putting up pictures as on wood walls. I don't bother with pictures. Luddite. ****wit. Cant screw into those every 2'. Must be a joist every 2 feet. Nope, every 4' as I said. These are galvanised steel I beams with one of the top flanges missing. Makes a lot more sense to have just 2 screws to hold the 20' of channel onto the bottom of the I beams that the 4' paper faced poly foam panels drop into. don't have to be central, they plug into each other and support each other. 20' and 40' channel works better. I'd say the best thing would be what I linked to, but longer versions, must be some somewhere. Even 4' ones would still be a lot more farting around mounting them that a single 20' piece of U channel with just a couple of screws into the bottom flange of the galvanised steel I beams which are at 4' centers. Your way sounds complicated to me. Because you have never had a clue. You have extra stuff to set up. Nope, just two screws per 20' piece of channel, leaves yours for dead. I just use the supplied clips and connectors. The strips of leds come with connectors and all you have to do is glue it into the channel. I don't have to have a channel. But have fart around with those fake fluoros. Or you can get LED tubes that fit into existing fluor fittings, just take the ballast out. The fluoros arent where the 20' strip of led would be and two 20' led strips in a 10mm U channel over each of the long benches would look vastly better. Much better than your leds too, they pretend to be fluoros. Stupid approach. The new technology should be done the best way it can be, not pretending to be the previous technology. LEDs are best in strips like mine, then they don't overheat. The flexible strips of LEDs in channel would have exactly the same number of leds per foot as yours and have an aluminium channel behind them so will dissipate heat even better than yours which have plastic behind them and are vastly better to mount, just 2 screws per 20' strip. And no connectors between each strip to fail either. They don't fail any more than any other electrical connector. They fail much more than no connectors at all, stupid. |
