Here's the e-mail that I sent to them
Their response was:I installed 5 white Mars Domes and 2 Red/White Mars domes in February of 2007. Of these, 4 of the white units failed such that they only turn on in "low" mode. One of the red/white units has also failed in that the white output is very low compared to the one that functions correctly. Based upon the common nature of the failure, this looks like a systemic issue.
Considering that I paid $70-80 per light and they 5 of the 7 failed at just over a year and they want $30/conversion kit to repair them, I'm not very happy. I've used a lot of their products in the past and have been happy with them, but this product seems to have some kind of problem.To obtain warranty service (within 1 year of purchase), please return goods purchased with a proof of purchase date, please send goods in with a $5 per item processing fee. Please send it to: [address clipped]Alternately, we can sell you our LED dome light conversion kit at half price as a repair kit.
I'm just about to take the units over to an EE friend of mine and have him diagnose the issue. I'll report back on what I find.
