So your temp inside the tent is 90 degrees and heatsink is at 95 degrees? Im a bit curious to know my heatsink temps but have no infrared thermometer. Hope you can figure out your cooling situation better to your satisfaction cuz the light looks awesome and no doubt it puts out a ton of light...

Sounds like very good plan.

I got the rest of my LEDs in and the stars sanded down flat and the driver and pk3 thermal paste showed up today. Still no heatsinks though. :cry: Anyone know how long it takes heatsinkUSA to ship usually? It says on the website usually the next business day its been 8 days since I ordered...

Nice! That baby has got to be cranking out some serious photons.

Looks like it might be root aphids, they are quite similar in appearance between the flying winged stage of the root aphid and fungas gnat life cycles. Root aphids are EXTREMELY hard to get rid of without the use of hardcore systemic pesticides which no one wants to put into a plant they will...

Thanks guys, it was actually a little low on yield about an oz less compared to usual with the 150w. Quality was very good though for sure. Still have some left with close to 16 months cure on it now. Smokes great. It was in FFOF, I dont remember if I added anything extra to the mix that...

I had been subscribed to this thread and wasnt getting notices for some reason but I just went through the whole thread today. Awesome stuff to learn about the different wavelengths you have used over several grows. Are those latest pics of the flowering plants in the 2x4 Lighthouse tent...

Sounds like they are power factor corrected, nice!

Watts is Volts x Amps. That would be with a perfect or corrected power factor. Power factor less than 1, the device will pull more current than it needs to operate. The amperage pulled by a non power factor corrected device, where it pulls more current than it consumes to operate, will always...

Got my Steves LEDs order already 2 days from payment to mailbox! Highly recommend that place. My 630nm are already in the US too, fasttech driver is on the way I paid a little over a dollar extra for faster shipping so hopefully it comes in a week or two. Heatsink bars should be showing up...

16 COBs @ 1600mA in a 4x4 sounds sick. Got any pics?

I love when you are the guinea pig and test stuff out for us. You spend your money on questionable items just to test them for the greater good of the LED community. Hats off sir.

Thanks for chiming in Guod. Yeah, I have messed with that spectrum analyzer thing before. The thing is I cant get the ratios of 3000k to 660 630 450 right, there arent enough spots on the "bar" that you put your led choices on. If I put 7 3000k on there, I can put 1 660 on and be about right...

If you can Id go another week or two on those. Doesnt look done yet.

Thanks for the input guys. I should probably (hopefully) be ok then since my WW COBs are putting out the vast majority of the light and the 10 660nm is only ~15w total between the two bars. Also since I will leave the bars off for the first 3 weeks or so that should help avoid the issue of...

Cool, thanks for looking out and for the info. I could assemble the bars with a couple less LEDs (less 660s) and run them that way but would be less wattage per bar too. Or I can order some more 630s and put those on in place of some of the 660s if its going to be a potential problem. I could...

Oh makes sense now. Yea I have never messed with LEDs other than my 2 COBs I got now. I was going to wait until after stretch to turn the bars on but still I hope they dont cause issues like you say. If they will I will probably sell the LEDs and get different ones or just make a pair of COB...

Not sure what you mean. Just 4 630 and 3 660? And what was that per bar? It would appear that way. It pays for itself over time but is a significant expenditure initially. If I started over again I would do a bunch of heatsink bars with Vero 10s or similar like MrFlux did. My height...

Adjusted side to side for spacing. I have thought of adding a third COB but I think it might end up being too much heat unless I added a third COB and ran them at 900mA each instead of the two at 1400mA. Already spent way more money than I planned to on these LED projects. Maybe in the...

So I purchased some LEDs, heatsinks, and a driver last night. To save on cost per 24" heatsink bar I bought 4 from heatsinkusa and going to use two for the R/B string in flower and the other two for the XML veg light when I get around to building that. Going to add two 24" Red/Blue LED bars to...
