Service was awesome. Quick to reply via email, but not if you send on their site. You have to copy the email address and use your own and they'll answer the next day. The site seems to lose the message.
I think it was around 2 weeks for them to show up. Maybe into the third week. They send extra led's in case you fry a couple.
Shipping costs were ridiculous, but it is coming from Hong Kong Fed x. Mine was $60.
Heat sink for son's kit was awesome. Good quality and came with the kit.
I like the Bridgelux, but don't have anything but the sunbrites to compare them to. Blows those away at less than half the price if you diy. Sunbrites were $300 for 6' tube @42w and these were around $150 including heat sink (from Steves) for a 6' tube, percussion fan and 120watts. Plus dimmable. I had to buy the heat sink from Steve's cause they didn't offer a long HS. I now see that home depot has a lot of long aluminum tubing that would've worked about the same.
We had to buy some extra wire at Radio Shack cause we wanted to move the drivers around. Also had to buy some project boxes and extra solder.
