Best 'instant on' CFL bulbs?
Getting a bit tired of CFL bulbs that take up to a minute to warm up
too 100% brightness, so can anyone recommend any 'instant on' 60 Watt (13 Watt CFL?) equivalent bulbs please? Thanks |

There aren't any, sorry. Trouble is, the run-up time is necessary for the high efficiency. For fittings I make myself, the 2D compact fluorescents are about the best in this respect, but that's also because they are slightly less efficient. They are better than they were in the dear old days but the best of the current (No pun intended) crop are still about 30% - 50% down at 1 minute, and another 30% down after 12 month's service.(All except "Dynamo" Hansen's, they positively coruscate within seconds of being energised). IMV Feit lamps from Costco (& others) are the3 best of a bad bunch Agreed. They are the only CFLs I've seen which actually have the correct filament equivalency printed on them (with 23W = 100W). They also seem to last very well, including in enclosed (hot) fittings. The 23W CFL lamps are bigger than 100W lamps, but are probably the shortest 23W CFL you'll find, and fit in more existing fittings than any other make I've found. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Also, go for the 'warm' colour temperatu the high colour temp ones make a room look cold and dark however bright they are when you look right at them. And our ones (the only kind we could get to fit in the narrow screw size at the time) rapidly became so dim as to be pretty well unusable. S |

wrote: I have been using compact fluorescent lamps for many decades. Some of the older ones were noticeably slow to start, especially the old glass bulb ones, as are some newer ones. Correct. These take time to warm up. However, despite long and loud assertions from some that it is impossible, I use Philips and General Electric compact fluorescent lamps in places like stairs and toilets where rapid light is necessary. These lamps are not noticeably slow to start. All a bit empirical that, especially from such a biased source. Please show us your measurements. As the lamps last a long time it is not possible for me to say anything about the lamps now on sale, the ones on the stairs and in the toilet are at least a decade old. Ditto. The exception is the bottom of the stairs. The SES reflector lamp I tried there was a little too slow to start (another poster has explained why), so I replaced it with a LED version. I use the slower starting lamps in places where a slow startup is not a problem. Where do you use the dim ones and what for ? Derek |

Whole life cycle , tungsten filament dash of bromide, quartz inner and glass outer enevlope steel and mixed metals connectors , not huge making or disposal energy cost, about 30% better energy wise tghan non halogen , nice light far better than CFL, CRI100 against CRI80 odd fro most CFL CFL glass outer, phosphor and mercury filled inner, tungsten in filaments, copper and electrmics in base , plastic housing questionable life span whole life cost not green at all really. Lighting aint in a domestic setting a great target fro energy savings. Cheers Adam |

That depends on the design of the lamp. I have not looked to see what is available in that sort of lamp, LEDs may not be quite there yet for a number of reasons including the colour. However, replacing a 60W lamp with two 1W lamps seems like a no brainer to me. I'm also not sure why a living room needs "instant" starting. The lamps I mentioned are fine in that sort of setting in my view. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000...#pt3-pb3-l1g54 |

What about electricity use over normal life of the bulb? Halogen should give you at least 2000 Hrs against 1000 of normal incan, 42W = 60W 70W=100W so roughly around 30% Turning the temp down on your heating and washing will save considerably more energy. Different if you need lighting off grid. Cheers Adam |
