Lighting Cobs to replace 150watt hps

[autoste]

I got the new heatsink today, drilled and tapped it, fitted the cobs and tested it for about an hour passively and it reached 110F/43C without any air movement, it will have quite a lot of air movement when its in the grow space so I'm hoping it will run quite a bit cooler.

Great little light

I have the same sort of heat sink bro 40cm long with 4 cobs on it running 188w i have put a 120mm fan on top with a old phone charger powering it and my heat sink never goes above 72f

Thanks man, iv'e seen a thread on here with one of those round pin fin heatsinks running at 115f, like i said it's a small space with plenty of air movement so I'm sure it will run cooler in there, wish i had the space for 188w!

Welcome And reps for getting it done. Even with little space you will have some of the most dense and frosty nugs around.
