I just looked at those. They are ridiculously expensive, IMHO.
The T-5 connector looks right for our 912/921 replacements and the single contact one looks like it will work with 1156 bases.
At 72 dollars per fixture (2 T-5 bulbs @ 38 bucks) these are so far out of my price range as to be useless.
"Very high efficiency of 70+ lumens per watt "
Yet no where does it say how many watts it pulls. At 200 milli-watts (about what my Hong Kong 36 LED pad draws) that 38 dollar plus shipping and handling lamp puts out a staggering (yawn) 14 lumens.
I like the idea of the built in heat sinks, but a small strip of "Extreme Velcro" will allow cooling air around the pad (which does get hot I will readily admit).
