Maybe I need a new monitor.
Or new math ... ;)]]>Jun 11th 2009 3:24AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Oh ... well, it was 9 bulbs anyway if I included the one on the left.

I still don't think that I'll be buying a $40 bulb anytime soon.
Nor do I want another remote control to get lost on my coffee table.

Does it still work with the clapper? Then ....

From the diagram on the site, it looks like the LEDs all point upwards... with a "coating" to diffuse the light. It seems like they will act sorta like a flood light pointing to the ceiling... with stray light hitting the lampshade.

The LED points downwards. The diffusion coating is for a couple reasons:
1. Because high-power LEDs give out a lot of light from a very small point, so without diffusion it would hurt your eyes.
2. Because I bet this is actually two LEDs: The power white one, and a power RGB one to control the "shades". The diffusor mixes both LEDs (otherwise it would be uneven).]]>Jun 11th 2009 5:52AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/.]]>Jun 11th 2009 4:12AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 4:51AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 4:48AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 12:02PMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
ELECTRIC CONSUMERS? is that like a robot shopper?]]>Jun 11th 2009 6:05AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
Still too expensice though, since for 39 Canadian, they emit less light than a standard 60 watt bulb.

We cant win as consumers. Either we choose CF bulbs which are energy efficient but are known to emit harmful rays, or standard bulbs which dont but are extremely energy inefficient.]]>Jun 11th 2009 6:51AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 10:24AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 10:41AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 11:22AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
As for environmental damage, even if you assume it will be released (e.g. in landfill) and not recovered, the mercury in the lamp is still much less than the mercury that would be emitted in the process of burning coal to provide you with electricity for the huge additional power usage that incandescents would require.

Since CFL bulbs are very cheap, very efficient, available in a range of colours, etc they are the best choice for everyone for all normal uses.

If you have special requirements such as dimming, small fixtures, frequent switching on/off etc that make CFLs unsuitable, then LEDs can be a good but expensive and not quite as efficient option, but I expect they will improve significantly over the next few years so you might not want to rush...]]>Jun 11th 2009 12:31PMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 4:19PMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
CFL bulbs do emit a small amount of UV radiation. Obviously not enough to notice for most people, but enough so that people with certain skin conditions that make them sensitive to UV light will react to CFL bulbs. I should know, i'm one of them. I'm toast in the sun, but even if i sit in a workshop with a raw fluorescent light, I will notice it later.

If you want a CFL bulb but dont want the UV radiation, make sure you get a lamp with a full diffuser or grating that blocks the direct light and illuminates by reflecting the visible light down.

I hope i know what i'm talking about, because i see a dermatologist photospecialist every month, and that's what he recommends.]]>Jun 11th 2009 7:05PMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
Also I'm not psyched about how they're shading the bottom of these LED/CFL bulbs with the heatsink. They say it increases light efficiency by directing the light downward, as it's intended, but they forget to tell us that a lot of the ambient light in a room is reflected down from the ceiling. And can you imagine how ugly the light pattern of one of these would be inside a lamp with a shade?]]>Jun 11th 2009 7:29AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 10:19AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 10:49AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
Wikipedia:
Because individual LEDs are low-voltage DC devices, implementing SSL to operate from mains AC requires well designed circuitry and a thermal case to dissipate the heat.

LEDs also have limited temperature tolerance and falling efficiency as temperature rises. This limits the total LED power that can practically be fitted into lamps that physically replace existing filament & compact fluorescent types. R&D is needed to improve thermal characteristics.]]>Jun 11th 2009 11:01AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/
High-power LEDs create insane amounts of heat concentrated in an insanely small point.

It IS energy efficient.. If you were to concentrate the heat a CFL emits across all it's surface on a LED-sized surface, it would destroy itself in a second and no heatsink would save it.

Not to mention that CFLs work better when hot, while LEDs get easily damaged by heat (and if you manage to get them running cool, they're much more efficient).]]>Jun 11th 2009 11:09AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 11:08AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 11:23AMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/Jun 11th 2009 4:15PMhttp://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/http://www.engadget.com/2009/06/11/sharps-remote-controlled-led-light-bulbs-generate-7-shades-of-s/sound sensor and remote interface. i am currently patent pending. i
built a very crude looking prototype however i would love to here
some feed back. here is a link or just google my name geno sirhan

p.s remember it is a rough working prototype so i know it does not
look good, but it works!]]>Jun 26th 2009 3:10PM
