I like more light! Questions about installing... The heat sink I'm guessing is outside the rubber seal. Did you do anything to ensure the seal stays on with the cable making an out-in run? Second, if the sink is outside the enclosure did you zip tie it to something to keep it from hanging?
Last - I see the bulb has a fan in it. With the seal on I'd think this would build up significant heat.
I'd love to try these - but I wonder about how the heat is dealt with related to how it normally seals.
