I just picked up a Philips LED Light Bulb that won the US Department of Energy $10,000,000 LPrize Award.
For the 60 watt replacement category.

10 Watts, 940 lumen's, 2700K, 92 CRI. Dimmable with a Leading Edge Type Dimmer. 30,000 hour average life.

Most vendors have them for around $49.99. My power company had a $10.00 incentive so I got one for $39.99
plus CT State Sales Tax and shipping. The lesser efficient 12.5W 800 lumen Philips ENDURALeds where $16.60
including the $10 incentive.

Those who have seen the alien head style of the 12.5 watt 800 lumen,Philips EnduraLED.
This one looks similar. Except it uses a few Ultra Bright Red LEDs along with the Ultra Bright Blue LEDs.
To cause the phosphorescent plastic covers to glow bright white.
When dimmed to a very low I could see the bluish red tint in the light.

Did not work well with a few automation modules.
LM14A. Flickered and went partially dim when On.
LM465 SS 08A01. Flickered and went partially dim when On.
LM465 SS 09J44. Flickered and went partially dim when On.
LM465 before SS no date code. Worked fine. Flicker one pulse when going On or Off near 0%.
Insteon 2456D3 LampLinc Dimmer Hw 4.3. Worked OK. Flicker one pulse when going On or Off near 0%.
Insteon 2477D Dual Band SwitchLinc Dimmer Hw. 6.5. Worked OK. Flicker one pulse when going On or Off near 0%.

Which tells me not to use Soft-Start modules with it.  I still think X10 dropped the ball when they introduced Soft-Start and didn't bother to change the part number.  I have 3 of them in my spare box, all marked with "SS" in the case with indelible ink.

I have seen some reports that the LPrize bulbs electronics are very touchy to what dimmer is driving them. Even a few on Philips list of approved dimmers have been reported as flaky.

Weather allowing. I may try the older Philips 12.5 Watt I have with the X10 modules.

The SS LM465s should be fine with most loads.

I tested the older Philips 12.5W EnduraLED Bulb with the same X10 modules.
The Soft Start LM465s are fine with it.
It seems to be the power supply in the LPrize and the Soft Start LM465s don't play well.

Side note. XTBM shows no noise from the LPrize and it doesn't act like a signal sucker either.

Did more testing.
The one pulse when going On and Off maybe how its electronics starts up.
It has both high brightness Red and Blue LEDs in it and they cause the plastic covers to glow.
The partially dimming at 100% with the two X10 Soft Start LM465s and LM14A seems to be how the devices electronics interact with each other.
The older 12.5 Watt one did work fine with the two LM465's and LM14A.

With an old revision 2476D SwithcLinc Dimmer. With an X10 addresses in it with my 1132CU.
I was able to do some dim% tests.
At 3% It would start from Off. The 12.5 Watt one was 13%

At 3% was bluish. 6% bluish red. 10%,13% 16% and 19% you could see the red and blue LEDs through the white glow.

DOE Video on the LPrize Bulb showing some of the tests.
I wounder how much it cost us for that fancy computerized tester near the end of the clip?
