Teen update :
Strawberry Diesel
KKP

These three have been topped and such and throwing new growth nicely. I did top dress on Sunday and I think they are happier for it. Kind of strange lately NOT MIXING UP NUTES and just top dress and water. Fans getting bigger , starting a little LST too.

3500k is really bushing things out. The other 2 bigger KKP have been moved to flower and the last 2 bigger KKP are still vegging a little longer ( as soon as LST tops start looking up ) !

Needed room as these teens were getting crowded .

You have got to be kidding about someone making claims with no backup!!! LOL this is by far the funniest post you have ever put up here. Because that's all YOU DO! :bigjoint:

If you don't like LED's fine, but you don't have to come to the LED section to crap on everyone else's threads right?
Sorry Charlie,get back up on your Harley... Exit out the party before I plant your body!!!

"HLG-320H-54 with 2 or more boards for 320 Watts" ( From HLG Website on QB288 ). I was told when I bought my V1's to use 240h c2100 in series.

I am mixing V1 qb288 and qb96e and too was wondering about watts and ppfd and the difference.. I was doing 160-170 w ( on 185a driver per ) at wall on each qb96e x 4 and 110-130 on the qb288 x7. I dont think I had the PPFD quit right. Since I added 2 more qb96e to make 2 triple fixtures I will lower the watts to roughly 110-125 watts at wall per qb96e. 2 qb96e are bright AF on a HLG 185h 54a ( parallel ). The 185 driver is showing 255+ watts at the wall ( good for 2 boards.. ).

I also am running a hlg 185h 54a driver to 2 qb288 v1 in parallel with excellent results, 255-260 watts max at wall meter. It also runs cooler ( acceptable to touch ) than the same boards on a 240h c2100a ( driver very hot, too hot to touch more than 3 seconds ) which showed 285-290 watts at wall. I am really happy with these 185 54a drivers, they push hard, 2.1 amp draw, the price is good. I also dedicated one to an Rspec as it was like 5-10$_more than a 120 54a ( dial it down of coarse ), thinking redundancy. I have looked at the 240h 54a and the draw is like 4 amps at 115/120v ( thats alot of draw/power ), I bet they far exceed 240 watts. My 240h c2100a maxes out at 2.5 Amps AC.

I plan on running around 120 watts max for all my boards ( using ac wall meter ). I should at least get a light meter app to do lux or something. If anyone has a recommendation on app for phone that would work as a guideline. please let me know.

1) How does the 288 V2 Rspec board being rated at slightly higher voltage than previous V2 translate to driver choices when building two-board fixtures? Instead of the 240h-c2100, or the 240h-54, could you safely run two Rspecs on a 240h-c2800? Or what about a 320h-c2100?

2) Part of the reason for the first question; how does a "260w Rspec kit/fixture" (that uses a 240h-c2100) compare to a QB Elite 360 / Pair of QB96s using the 'stock' 320w CC driver.

I'm thinking the pair of QB96's have more potential, but ran at "recommended" levels I wonder how they compare (ppfd etc). The spectrum on the Rspec looks nice, more "full" blues. The Rspecs spectrum *appears* to be a slight "improvement" (or at least increase) in a couple of wavelength areas...?

Thanks for any input.

Question. Checked the wattage at the wall on each of my hlg 135 units. Have two right now. Both were running 120 w. I turned one to 130w and the other to 134w. Is that okay? I don't want to burn them out. Thanks.

I use one, duno if it's good or not though. Lux Meter (Light Meter).

Your hlg-185h54 draws 260watts? You run two QB96's on one hlg-185-54 and get 260watts out of that? What? I know the 240h-a-types draw about 260-265watts max. So I'm a little confused with what you're saying about your 185h's.

THe watt measurement is a meter you plug into the AC outlet and measures from the 120 v draw of the driver, which shows quite high. Most are measuring on the DC side which should be lower I believe. I will invest in a DC meter so i can measure that side of the current. Has anyone else measured these drivers from the wall? The meter shows the amp draw bang on at 2.1 amps 185h 54a and 2.5 amps for the 240h c2100a ( as spec ) both maxed out.

Yea - I understand all that. I am referring to the AC watts, same as you were. Still, doesn't make sense to me. A 185h driver pulling 265w at the wall?? That't way more than the 10% overhead an a-type (for example) would produce above it's "rated" output. What you're suggesting, and I could be mistaken in this, is that your 185w driver is drawing 260w at the wall - that's like 30% more than 185w...I don't get it.

Also, you talking about a kill-a-watt meter? Yea, I have one. I have multimeters too. :)
If looking for a good multimeter (said you need new/one that does DC as well?) check out eevblog or jrmorton (I think) on youtube - they have some recommendations. Bryman make good meters from my research, greenlee rebrands them in canada (someone else rebrands in the U.S. I think).
Duno what your price range is.

Thanks.

I posted this a few pages back and have since added FR to the 96e fixture. The 260 diy kit at each end is shown in last pic ( can't see the once above camera ). I have since replaced that center board with Rspec and added 2 qb96e as seen. Since I am using 1 driver per 2 boards now ( except rspec has its own driver ) I lost 1 driver ( 240h c2100a ) which will be repurposed for 4 x qb120. That 240h c2100a driver was showing around 285watts on my meter. THe 185h 54a shows around 255watts. So the output isn't far off. I was happy the 185h wasn't super hot maxed out w/2boards. So in other word the 185h driver is working better for me than the 240 c2100. And the price is much cheaper. A worthy driver for sure.
