LED upgrade
I took the plunge and updated several of my incandescent bulbs to LEDs. I didn't do anything with my fluorescent fixtures because they are quite efficient already. I purchased 14 of the circuit board type units, 10 warm-white and 4 white from eBay. The vendor is in China of course.
Here's a link to the eBay store: duan-led2010.
They are also known as 2011_led. It took 9 days for delivery.
10 pieces - Warm-white: 10x BA9S/T10/Festoon Dome LED Bulb Warm White 12-5050 SMD leds
2 pieces - White: 2pcs BA9S/T10/Festoon Dome LED Bulb White 12-5050 SMD LED panel
I placed the warm-white LEDs in my reading fixtures, and the white LEDs over my stove and in the porch light.
Here's some photos of the project:
LED board with plug attached.
I removed the wires and soldered the plug direct to the board and glued the plug in place.
I used PL-Premium to attach the plug. This stuff is the greatest.
Board plugged into reading fixture.
Shot comparing 921 bulb with LED. Shot at night with the single fixture turned on.
I checked the light output using a photographic light meter.
For the side-by-side comparisons, the camera was set for manual exposure, auto white balance off, and white balance set for daylight. The colors look quite different in the photos, but to the eye they seem much closer.
Voltage: 12.7 vdc
921 bulb current: 1.30 amps
LED module current: .17 amps
Measured with a Fluke 77 multimeter.
I'm quite pleased with the results.
