LED Bulbs

Looks real good Ron. Have you had a chance to measure the current drawn by one light?

No I have not measured a completed fixture. To get current-draw (wattage) figures from my place of work, I only brought in one 11 segment (33 LEDs) strip and one 1 segment (3 LEDs) strip.

Amperage measured at 12 volts....
The 33 LED strip calculated to 4.17 watts
The 3 LED strip calculated to 0.312 watts
Remember there are two 33 LED strips per fixture

The engineer and I found it strange that the 33 LED strip was so much more than 11 times the 3 LED strip. It is hard to determine why so much a difference. We'd would accept some variation, but not 20%. I am thinking of bringing to work my surplus material for more measurements but taking measurements would require cutting my surplus strip into 33 LED samples.

If considering the 3 LED sample, each fixture would be rated at 6.8 watts, not 8.3 watts. It is around half that of the florescent lights, maybe even 20% better yet. I also feel that if you wanted to reduce the strips from 33 LEDs to 27 LEDs, the lights would still illuminate effectively, especially with lighter colored interiors. I max'd out with 33 LED strips because of our dark cherry cabinet finish. A little more light seemed the better idea.

Apparently it is as vague as fuel economy. I accepted that I won't really know how much power consumption was reduced, just happy it is a lot less along with more light, a warmer color tone, and also now having the integrated night-lights.
