I do. Send me a pm with what you need and I’ll get them out to you. I will do a few more updates until the cobs arrive.
No I snipped the leds off then sanded it flat. It tears up the sandpaper though. The beauty is it’s already drilled for the heatsink and mounting so it’s actualy a money and time saver too.
The down side to this pile of crap is it’s size. The drivers are 100-140v so there is room for 6-36v cobs or 4-50v cobs between the 2 driver.
All I did was used a smaller drill bit and put some pressure on the screw and it easily threaded itself.
Just had an idea that may work even better. The heatsinks on this light are poorly positioned. To make things easy as possible I’m going to reposition them directly behind the cobs. Makes sense now but initially I was trying to coordinate the cobs around the heatsinks. I’ll take out the cob holders and drill straight through the heatsink as a pilot. Then take the heatsink off and drill a larger hole so the cob holder screws don’t push the heatsink out. Confusing to read. I’ll get more pictures soon.
It depends on the driver. I’d guess there are 3 in there as the 150w has 1, the 450w has 2. You may possibly be able to fit 6 cobs in there. If so your looking at 210 wall watts roughly. 100+ par watts vs 50.

I've been told that because my output voltage is 140v and my 2 cobs are only 36v each it would blow them, is this right?

No that’s wrong. You can run 1-4 cobs on that driver. I wouldn’t go much above the minimum though.

Do you already own the 36v cobs? I’d recommend a 50v for a few reasons. Lower amperage and still achieve a higher wattage. The drivers have low amperage as it is. So getting the most wattage is ideal. Also the size of the panels are very small so having 6-36v vs 4-50v would take up more space. In the end both options are good and please don’t take it like I’m trying to sell you anything either. Version 6 1812’s have a much higher efficiency. Than most available version 5 1212 cobs. Also stay clear of eBay cobs too. They can be as low as version 3 from what I was told from the distributor. If they are cheaper than you can buy them direct there is a problem.
