<div>Rick, </div><div>I spent a lot of time on my light project, initially looking for & buying lights & housings on line, that I could adapt. </div><div>I ended up buying 70W leds & making my own housings. The housings I had marine anodized. I had to get an led driver designed & built in China, as I wanted dimming. The driver is a constant current step up, step down (buck boost) that takes a 12-60V input. </div><div>I had the lenses made up in China; 20 for about $2- each. The units were tested to 1000psi. Have used them quite a bit in caves! They get hammered in that instance because they don't have the water cooling & can get very hot. </div><div>Other people have oil filled spot lights used on off road vehicles successfully, but I wanted more of a race car look to my sub & wanted to avoid the oil. </div><div>If a housing or light came up that was suitable & easy to adapt I would use it. </div><div>But bare in mind that most online lights would need marine anodizing. </div><div>Alan </div><div><br></div><div><br></div>

I asked my friend to buy some more and he said that the source in Japan does not sell them any more. </div><div> I found something similar here in the U.S after hours of searching that matched pretty closely to what I had but they were about $38 each.
