If you aren’t familiar with me, my name is @OZs_786 , go by O.Z. , or just — Z. I am looking for advice on adding another grow light indoor. My outdoor spot I was hoping to move may be compromised —and I don’t want to risk it right now. I am looking for something that isn’t high wattage and is preferably HLG QB. I have a 65V2 and am looking for something that is possibly a little higher wattage — but runs 3 or 3500K for better flower spectrum, as my current light is only 4K Space is only closet space about maybe 1.5x2 haven’t gotten around to measuring, but I do have some space upwards so moving up some isn’t too much a problem. Any help would be of help blades. Thanks for all the help so far — been LSTing all my girls under this lamp and they are vegging beautifully
I was thinking something with higher wattage if not the same wattage, not sure I have space to fit 4 of those QBs. I would purchase another 65, she’s done me well, but I’m not sure where I can find a 3500K or 3K 65v2 Also don’t know much about setting up with separate drivers and all that
With heat sink the QBs 288 are like 7 x 11 inches. So the right frame build u could easily fit 4 if the 120/132 without heatsinks in there
QB288 V2 & Slate 2 Single Combo HLG 100 V2 Hlg only makes 65v2 in 4k The 144 look promising for a smaller space also
Was just looking at the 135w .. I think that might be too much but I can’t seem to find the 100W kit on their site.
Just dim it. It actually gets more efficient dimmed. Atm I’m in a 2x2x4. I have a 288 on a 120w drive at full power and a 96v2 on a 80w driver at full power. My temps max at 77.6
Might just have to look into that. Thanks. I’m not too knowledgeable indoor when it comes to lighting and stuff, but which K would be better to supplement along side my current lamp. I’ve only seen mostly 3K options but would a 3500K be good along with my 4000K or would yields be more larfy. Would supplementing my 4K even help yields?
I assumed feet bc he said he has room to move up(head room) and he didn’t think 4 qb120 or 132 would fit in there
very possible, but just from personal experience I've learned if i don't ask I usually end up giving wrong or incorrect info. I try not to assume anything anymore because I'm usually wrong.... found it's just easier to ask. edit: sorry, i realized you replied to Sc00by, not me
Definitely feet, sorry I didn’t mention it. I’ll have to get around to measuring the exact space, when I get back home today
1.5ft x 2ft. ok, pretty small space so easy to fill, especially since you imply you can go up so you must have some vertical height to work with. assuming standard 8ft ceiling? if that's what you have to work with I think the best and easiest solution would be a single qb96elite for $99.00 and a driver such as a HLG-185h-54a. the qb96 will flower a 2x2 area so you should have plenty of coverage from the single light and you have the height needed for good spread/coverage. light/driver/wiring/hanging access you will still be well shy of $200.00. very good light, great spectrum In your area you only need approx 90-120w (30-40w per sf) of good LED lighting. This light/driver combo will easily give you almost 200w if you want to push it but you can rub it dimmed way down so you gain efficiency plus it will run cooler. i honestly can't think of another solution for your size area that would be better spectrum and anywhere near the power capabilities this is capable of at that price point.
an HLG-185 would be way overkill in that space. I would go with an HLG-120-54 and even then it can supply more power than you would need if pushed. Meanwell drivers perform better the closer to max you run them btw.
was just figuring he could dim it down to very little and have a lot of power on tap if he ever needed and figuring that the more dimmed down they run the more efficient they are. not sure what you mean that they run better closer to max? they run fine at max, but hot. dimmed they run cooler and more efficient. The MW drivers can run HOT if you push them on the loads. run dimmed down they run a lot cooler. may or may not be important depending on where he want to mount the driver. but you are not wrong, the 120 driver is probably enough power and would work. Guess I always prefer the idea of going higher power and running it down and easy vs running a driver harder. personal preference difference i guess either should work well for him.
He would never need more light in that space unless he ran CO2, even then it's probably enough with the 120, we are talking about 3 square feet. As for efficiency what you say is true when tallking about the boards themselves but the drivers are actually made to run better the closer you are to maxing them out. If you look at the data sheet for the HLG series you will find this table that shows it clearly, even at 70% load you start seeing drop in efficiency.
honestly, never saw that chart. i was going by pretty much everything tbone always said about the drivers anyway, we at least seem to be in agreement on the 96elite. you haven't shot down that idea yet...
Tbone will tell you the same thing, that data is from Meanwell directly: HLG-120H-MEAN WELL Switching Power Supply Manufacturer
