Well it's the early days but I installed 8 of these units and after a day I haven't had any failures and the lamp bodies and miniature drivers seem very cold compared to other 3" and 4" LED units to be. I use. I bought 5W/4000K units. I'll be ordering a few replacements in case I run into problems in the future, but so far I'm impressed with the build quality and design. Thanks to the gimbal design, they should be able to reach images well. The only note I'd like to mention is the electrical unit in the press release, which I've replaced with caps to make it a little more reliable.
