Test on an Ecosmart Dimmable LED light bulb.
« on: November 13, 2010, 12:52:43 PM »

I recently picked up an EcoSmart Dimmable LED bulb from Home Depot.
Model: ECS 19 W120
9 Watts
120 Volts 75Ma. 60 Hz.
A19 Bulb Style
Bright White 3000K
Kill A Watt Meter:
0.06 Amps
07 Watts
07 VA
Power factor 0.98-0.99

XTBM didn't show any X10 band power line noise and there was some signal absorbtion when on.

LED beam is towards the top. So down mounted socket would be better. Table lamps seemed to light the ceiling.

LM465 Lamp Module. Old style; newer Soft Start and latest Soft Start. All worked well and dimmed nicely.
WS467 Did not work stayed at 50% and did not follow any X10 commands. Sometimes worked with the local button.
2456D3 LampLinc worked well and dimmed smoothly.
2876DB Icon Wall Switch Dimmer. Worked well and dimmed smoothly.
2000SC and 2000SHL Smarthome X10 dimmers. Worked poorly and filckred when dimmed.

Here is a link to a thread where someone disassembled one, some say smashed it.
It looked like the LED driver chip was made to be in a typical dimmer circuit and that maybe why
it dimmed well. With most switches and modules.
