How Much Power Savings using LED's?
Just purchased 4 warm white LED panels with 20 5050 LED's. Wanted to experiment with these on my TT before purchasing more.
Anyhow, one 20 5050 LED panel wasn't nearly as bright as the original 921 bulb in my TT. Tried two panels and it was as bright, or maybe slightly brighter than the 921. Noticed there was pretty significant heat being produced by the two LED panels, so I became very curious about the amount of current these puppies were drawing. The two 20 5050 LED panels (total 40 5050 LED's) were drawing .59 amps total. For comparison sake, I also measured the current draw for one 921 bulb--1.3 amps. Wow, unless my eyes are misreading the light output of the 2 panels, using LED's only cut my current draw in half vs. using the original 921 bulb! A 50% reduction is still fairly significant, but not nearly the savings I expected.
Curious what other have experienced. How many 5050 LED's have you needed to replicate the same light output as one 921 bulb?
