Turning light bulbs green

Like pornstars! Sorry, just had to! [/QUOTE]From light bulbs and lamps to pornstars????? WTF???

Maybe you should stick to your Nazi/white supremacists websites Bithron and stop derailing my Ironwork threads?

Thx in advance

Hey, come now. If you gotta yell at the man, do it over PM, no reason for us to get all aggressive here.

As for LED lights, they seem to beat incandescents at power efficiency, but they are even more expensive than fluorescents, plus they require optimal situations or high production values to have that high efficiency.

As far as I can tell, they're also less efficient for room lighting since their light is more directed.

They're also worse than both incandescents and fluorescents when it comes to producing broad-spectrum light, according to what I'm reading, which means an increased chance of SAD-like symptoms for people who spend a lot of their time exposed to them rather than sunlight.

Don't forget that with the fluorescents you can't just throw them out. They have to be taken to a hazardous waste site. Mercury you know. CA says they have to be handled as hazardous waste. Can you say more money?

Is CA really stupid enough to charge people to dispose of compact flourescent bulbs? I find that a little hard to believe.
Generally goverments have discovered that charging people to do something that is already inconvienent is a good way to get them to put a lot of effort into not doing them.
Compact flourectent bulbs can be recycled, so there is no good reason to charge someone for trying to dispose of one.

Originally posted by ladyzekke: Hmmm, maybe I got a bad bulb. I tried a 2-pack of those spiral ones last summer at work. After about a month the one I put in the bathroom started to flicker constantly until I finally tossed it out before it drove me insane. Now the other one that I put in a banker's lamp at my desk didn't flicker, much, but it was so heavy it actually weighed down the part you screw the bulb in, so the bulb leaned and made crackly sounds. So I thought they were crap, but perhaps I'll give them a shot again. However, again, they are kinda heavy for certain lamps (banker's lamps you put the bulb in sideways).

If there's one thing worse than fluorescent light it's flickering fluorescent light. Tzz Tzz Tzz.

Well thanks to "B" I conducted very little research on alternative lighting sources.

I might be able to shed a ray or two on this beaming subject:

1. The newer high frequency bulbs are very stable and produce near "Daylight". My 13W desk lamp runs at a 6400K (Kelvin) temperature producing a CRI (Color Rendering Index) rating of 92. It is truly amazing. The first link below makes for a good critical analysis read.

2. My reading lamp, is the 18W "Ott-Light". It has had some minor issues, but the company was *VERY* user friendly, prompt and actually seemed concerned with customer relations. This lamp does need a few moments to warm, but once it's hot, it lights my study area as if it were the mid-morning natural light peering through the window shades. I will never go back.

3. A final cheaper alternative, but not low wattage is the "GE Reveal" bulb. These produce a smooth, non-glaring usable white light.

4. I have tried different brands of the replacement low wattage bulbs. The "GE" seems to respond slower, but produces more light once it responds. They also seem to create a harsh glare, or 'hot spots' if you will. The "Sylvania" responds quickly, and slowly builds to full capacity. It seems to radiate more efficiently, and does not have 'hot-spots'. I prefer the "Sylvania" and the spousal unit prefers the "GE".

Great post felix, thanks for shedding some light on the subject [img]graemlins/petard.gif[/img]

We already have most of our bulbs replaced. But we didn't do it all at once. We did it as they burnt out. I think we may have two or three left that still need to be replaced.
