Does anyone else have these? I have a few myself but I have not set them up as yet.Liquid Lumens Hydroponic Lighting - eBay (item 220225017379 end time Apr-23-08 18:40:11 PDT)
There not $500...there $1,000...$500 is just the starting bid. WAY overpriced for somthing so simple.
You guys should check these out. Much cheaper, safer, and simpler than the LL product.
You can use these to water-cool your light and add a/c to your growroom. They come in 6" right now but the 8" will be out soon.

These guys make the water-cooled co2 generator also.
Good luck with your liquid lumens, but don't run them out of water or you will have a mess on your hands. If you run them out of water they will melt, and if any cold water is reintroduced to them while they are hot you will have a pile of hot glass and hot water all over your plants. I'm speaking from experience, trust me.
