I have a set of 3 CXB's. They were $58 each. I like them. I know nothing about the CXm series. Looks like they went from cxa to cxb to cxm? Lol. My only drawback was the price and with Bridgelux being $20 cheaper and pound for pound doing the same job I primarily use Vero's. I want to try...

Thanks a lot man. I spoke to Jamie. He's gonna ship me 6 140mm heatsinks for $13 shipping. An amazing price. I'll definitely check out any light you recommend. I'm an analytics guy not an electrical engineer (unlike plantactivist who is probably both and obviously owns Bedrocan and invented...

Thank you. All I want is some heatsinks. I only came for the goddamn heatsinks!!! Lol.

I'm using the Bridgelux Vero 29 BXRC-40E10K0-D-73-SE. It's a brand new chip. I just got 3 and I'm testing them against the BXRC-40E10K0-E-73 from last year. But I need passive heatsinks.

Wow. You're the Best. I was ready to run out and buy an apogee meter at $600. I'll be assembling close to 300 COBs in the next year as I've applied for my LP cannabis license and have been approved for a 100 plant R&D grow. The only reason I joined is because I spoke to the OP on Thursday...

I don't know about Cree but I had my Vero29's put under a PAR meter and at 50w I got 850 U/mol at 3 feet. At 75w I got 1186 at 3 feet and at 90w (I started getting a 60 cycle hum above 90) I got 1490 u/mol. That's 4x what a 300w HPS puts out at 3 feet. I didn't have a laser thermometer so I...

I have no idea. I drive mine high at around 75-90 watts. I get better effacy and efficiency at that wattage. I use top bin COBs and only Meanwell drivers so with the right cooling I can "drive the hell out of them" and turn those 11000 lumen COBs into 18000 lumen COBs. Maybe some people are...

I contacted you about 6 of your Econmy heatsinks and a HLG-240H-C2100 driver. If you can get what I need I'll move all my business to you and stop using DigiKey and Mouser. I'd rather go with one small company that can get everything I need instead of 3 companies for 3 items. My company is...
