LED v CFL bulbs
My house is mostly lit by cfl lamps, apart from a couple of LEDs used as
bedside lights. I am thinking about switching to LEDs throughout. Is this viable? Pros and cons? I would value your opinions. Thank you. |

That's generally regarded as an annoyance. If you want them to come on gently, use a dimmer (if the lamp type will tolerate them). -- Max Demian |

LED v CFL bulbs
Also some do not like the suddencut off in lighting area of leds, but they
are , apparently getting better in this respect now. My one concern has been that some LEDs have some kind of switch mode psu in them and kick out rfi at an alarming rate, but I'm sure these are mostly the el cheapo ones. Obvioulsly myself I hardly use lights these days, but as long as you get the right colour temp for what you need then I think LEDs are more efficient, and come on faster.

Well, actually they come on at full bright instantly. That alone saves current, because I feel more inclined to turn them off, knowing there will be no delay when I switch them back on. |

I just bought a couple from B&Q (yes, I know, but I needed them _THEN_ to go with some new lights). Much to my surprise they take a second to come on. And are completely flicker free. Andy |

I have a Philips Hue LED bulb and I am very slightly aware of multiple images, in different colours, of the bulb if I am looking at something on one side of the bulb and then look to something on the other side. I wonder if the various LEDs that make up the white light are pulsed in sequence rather than all being fired simultaneously although with different mark:space ratios to get the desired colour balance. Also, can you get an LED bulb yet that is as bright as a 25 W CFL which is I think is equivalent to about 150 W tungsten? The other thing: LED GU10 spotlight bulbs have a very narrow beam with sharply-defined edge, whereas tungsten GU10s are wider and the cutoff is more gradual. If you have arranged tungsten spotlights to give fairly even coverage, you may find dark patches in between if you switch to LED. I'm not sure whether there are CFL GU10s. |

Not all LED GU10s have narrow beams - mine cast a similar beam to the previous halogens, which were wide beam (can't recall exact angle but remember going for widest available!). You are right though, it pays to be careful when selecting them. -- Biggles ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

My guess is they have a very special tungsten 100w they used for comparison. I've heard that the claimed lumen output from LED bulbs is often overstated. Apparently there is an acceptable tolerance in stated lumens to account for the variation inherent in tungsten bulb manufacture. But LED bulbs can be manufactured to a more precise light output, so manufacturers can claim a higher lumen value while ensuring that the bulbs will fall within the acceptable range. I've also heard that some claims used to be based on the output from the LED chip rather than the entire bulb. I'm not sure if this still goes on, or whether it's been banned. |

ISTR the comparison was against a pearl 100W lamp - and then probably a 240V one running at 230V just to help manipulate the figures:-) BTW I put a lightmeter app onto my phone the other day and compared it to the proper lightmeter we use at work. It was surprisingly accurate. -- Adam |

Its obviously going to cost a bit to change them rather than wait till the cfls fail one by one. One advantage is that you can get leds that you can change the color temp of with a switch which cant be useful in some situations. And the good ones last longer and are easy to do in led strips. cfls are more concentrated light. I would value your opinions. |

Me presented the following explanation :
My house is mostly lit by cfl lamps, apart from a couple of LEDs used as bedside lights. I am thinking about switching to LEDs throughout. Is this viable? Pros and cons? I would value your opinions. Pros.. They come on instantly to full output, last considerably longer, cheaper to run. Cons.. None really, though some complain about the light spectrum. I converted all of my regularly used/regularly on lights, over to LED 12 months ago - not a single failure so far. They vary from 3w to 9w. Just to be clear, I did only swap out the ones which we use often - I didn't do centre lights and some were 22w CFL's. |

None really, though some complain about the light spectrum. I've completely swapped to LED over the last two years and no failures yet. I took the opportunity of fitting (surface mount) LED panel lights in the bathroom, kitchen and hallway which I've found give a nice even spread of light. As for the colour temperature of the LEDs its really down to personal preference and you have to ignore those on here who preach that those horrendous warm yellow bulbs of yesteryear are more natural because they are the same colour as the candle chandelier they replaced You may find that for close up working or reading if you are of a certain age and/or don't have perfect eyesight then a colder blue or daylight type temperature LED suits you better. Buy a couple different temperatures LEDs and try them out. Relegate the bulbs you don't like to somewhere that is used infrequently. -- mailto: news {at} admac {dot] myzen {dot} co {dot} uk |

... I've completely swapped to LED over the last two years and no failures yet. In the past two years, I've had two LED GU10 spotlights fail. They are mounted in a modern 5-spotlight strip that is also two years old (so it may have been made with LEDs in mind - or it may not). The symptom is pronounced flicker, then the bulb goes out or fails to come on when the main switch is next turned on but does come on if the switch is cycled off/on. LED bulbs are very fussy about the ventilation of the light fitting (the cylindrical shank of the bulb). The light-emitting part of an LED bulb barely gets warm but even a 7W one gets almost too hot to touch close to the fitting. |

I swapped some 100w 100mm ES floods for 9w LED's in the kitchen, backed up with a hidden 6' fluorescent for additional light as needed. Those 9w wide angle flood lamps barely get warm when on and have been in use for 12 months now. I would get concerned about the life of any LED getting near to too hot to touch. |

Buy a couple different temperatures LEDs and try them out. Relegate the bulbs you don't like to somewhere that is used infrequently. Except nearly all the bulbs I have seen on sale are 2700K 'warm white'. |

Buy a couple different temperatures LEDs and try them out. Or buy the fancy leds that can be set to any color temp you like via the app so you can have a different color temp when doing fine work or reading and when doing other stuff like ****ing the slut etc. Relegate the bulbs you don't like to somewhere that is used infrequently. |

None really, though some complain about the light spectrum. I converted all of my regularly used/regularly on lights, over to LED 12 months ago - not a single failure so far. They vary from 3w to 9w. Just to be clear, I did only swap out the ones which we use often - I didn't do centre lights and some were 22w CFL's. I went nearly all LED a few years ago (I cannot find an LED light that would be a good replacement for my outside floodlight). Swapped the gf's lamps about a year later. Not one failure. However I have fitted thousands of them and I do see failures - usually in the the first week or so. But not that many. -- Adam |
