Electronics question (before I kill myself)
Went to buy oen of these today so I could do some garden work in the dark -
idea was that it would stay plugged into the mains while I worked and then taken off after (never hung up) http://www.screwfix.com/prods/86568/...ack-Floodlight Eventually I got one of these: http://www.screwfix.com/prods/11281/...00W-Site-Light which is the same but with a plug The reason I didn;t get the first was that it didn;t have any wiring with it at all and for soem reason I assumed it would I did consider buying the wire and plug myself but I don;t have a clue to be honest, probably would have ended in disaster Can anyone explain what I would have needed to do? How would I know what fused plug to get? What wire? It siad it HAD to be earthed yet there was a lot of non earthed wire being sold What is eletrical insualtion tape used for? Anyone know a good beginners guide for all this? |

Anyone know a good beginners guide for all this? Let's just say you did right by buying the one with the cable and plug already fitted, and leave it at that. Working under a single floodlight is very different from working under sunlight, more so when the light is at low level and liable to dazzle you. I wouldn't use power tools, for one thing if you have an accident like damaging the cable you might blow a fuse or trip an RCD and plunge yourself into total darkness at a critical time. -- Graham. %Profound_observation% |

These are good http://www.lampbulbs.co.uk/product_c...e.php?catid=33 Slightly more expensive to buy than a standard lighting system, but they make up for that in running costs and the lamp life. |

Eventually I got one of these: http://www.screwfix.com/prods/11281/...sk-Lighting/Si... which is the same but with a plug And also with a convenient stand and carry handle so you don't burn yourself or set fire to things. Those lamps run *hot* The reason I didn;t get the first was that it didn;t have any wiring with it at all and for soem reason I assumed it would No, it's intended to be installed into a permanent location with fixed wiring I did consider buying the wire and plug myself but I don;t have a clue to be honest, probably would have ended in disaster Can anyone explain what I would have needed to do? (Probably) fit a strain relief gland to the lamp. Fit an appropriate length of 3-core flex rated at 6A and a 13A fused plug with a 3A fuse. If you wanted to be really pernickity, then test the entire assembly for compliance with British or EU standards ... How would I know what fused plug to get? Watts / Volts = Amps. What wire? It siad it HAD to be earthed yet there was a lot of non earthed wire being sold There is a lot of appliances that don't need earths. What is eletrical insualtion tape used for? Bodging things, mostly. Anyone know a good beginners guide for all this? Readers Digest / Which? / etc book of wiring and lighting. Your local library should have something. Incidentally, in case your house wiring isn't protected by an RCD (residual current device) I would strongly suggest that you get one of thesehttp://www.screwfix.com/prods/15263/Electrical/RCDs/RCD-Adaptor plug it into the socket in the house, then plug your outside lamp and any tools you use outside, into it. Owain As has been said, a CFL light would be better, but halogen works. 500w is way OTT though - you can get lower wattage bulbs that will fit, or really best to go get a cfl light. Even better get a pair, then you're not working in hard shadows all the time. I wouldnt recommend using power tools under a blindingly bright light like that. NT |

Do just cut off the supplied plug and fit a normal 3 pin plug?" :) I used to sell pressure washers to the tool hire trade, 110v ones were a nightmare. They would leave the factory with a 32a/110v plug fitted (2kw motor). We wold invariably get a service call a few weeks later, to find the 32a plug had been swapped for a 16a one. Affixing a very large bright yellow sticker to the front of the machine partly solved the problem, but never stopped it 100%. -- Dave - The Medway Handyman www.medwayhandyman.co.uk |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Graham." saying something like: Working under a single floodlight is very different from working under sunlight, more so when the light is at low level and liable to dazzle you. I wouldn't use power tools, for one thing if you have an accident like damaging the cable you might blow a fuse or trip an RCD and plunge yourself into total darkness at a critical time. Oh, FFS. |

All that was wrong with it was the internal light did not work. on closer examination there were two Quartz Halogen 120v bulbs wired in series and one had failed. Sourcing a replacement was too hard, I think the oven was written off. -- Graham. %Profound_observation% |

You must have had the same customer as me :-) I saw the same thing when I was a TV engineer back in the '70s. A 3 KW heater had a flex extension using figure of 8 stranded twin (solid bell-wire would have taken the current better) The join was made with the old woven fabric type insulation tape and it was connected to a 13A plug with silver paper from a cigarette pack wrapped round the fuse. The cable was hidden under the carpet though, so at least no trip hazard :-) -- Graham. %Profound_observation% |

As we ate the choc block sat by the edge of the table - perhaps they were trying to discourage people from spilling drinks :) NT |

Although strobing occurs very occasionally, the thing still doesnt look like its stationary, since the fl tube gives out light over a fair percentage of the half cycle. I've never actually seen it in my domestic workshop when it was lit by 50 Hz fluorescents. But then I don't have slow turning heavy machinery like a lathe. That only happens with mains frequency fluorescents - and only with crude tubes. I dont think I've ever encountered a domestic/commercial/industrial tube that doesnt produce 100Hz output when run on 50Hz. Are you thinking of a special purpose type? Anything with an electronic ballast. They run at about 30kHz and are more efficient. That's what I now use in my workshop. Tubes seem to last longer too. Modern electronic ones run at such a high frequency that strobing won't be apparent. Or use high persistent tubes.
