My QB Setup

[GrowGlow]

I've been using QB Type LEDs for a while now. Current setup in a 4×8.




The QBs above are V1s, V2s and V3s. A mixture of LM561C, LM301B and LM301H diodes. 3000K + 4000K for white diodes. The supplement Red strips are Osram 660nm + 730nm. The UVA strips are 395nm Epistar diodes.

Each QB Board has around 800 to 864 pieces of diodes. They are each fitted with a 320W Meanwell driver but does not exceed 50% power. The objective of this setup is to drive the diodes very softly to reduce heat and possibly allow plants closer to light.

The UVA is turned on at 2 x 4 hour intervals.

So far, has been working well for me. Thanks for reading!

Nice setup mate, looks like it cost a few pennies but very nice. Which Meanwell drivers are you running A/B or A&B? and are you dimming them or just under voltage / under current with them?

Love the UVA/B strips as well. I did a little playing with a cheap tropical UVAB bulb from Amazon and I defo think it makes a difference.

Very cool set up @GrowGlow. Canopy of light and decent light at that to. Fair play mate.

I've both the B and AB. Each board usually don't exceed 50% power output.

Thank you Sir!

I would recommend getting the type 3 with both the A & B as they give you 3 types of dimming and allow adjusting both the voltage and current and they don't really cost much more than the A or B. Downside being they are harder to get hold off.

I believe newer models are now all AB. I use a potentiometer or dimmer on each driver so B or AB don't really bother me much.

very nice setup ya have built there , always love some diy builds

That is good to hear as they are just so much more flexible in terms of dimming. In terms of controlling the output (volts/current) I was thinking more about people who ever want to re-use the driver. Doesn't really make that much difference when they are pre-packaged with a light (but the 'old way' of sticking a screw driver in a tiny hole did kinda suck for dimming) but if your building your own light or just buying the driver separately I would say get a type 3 if you can as they are both Constant Current and Constant Voltage compatible so give the best of both worlds when it comes to deciding how to wire up your boards.

I purchased the wrong one and got a type A when I actually wanted/needed a type B (later found out they made the A/B) so learnt the hard way and it was originally purchased for Automation so that fecked me up but I ended up getting it for Free as it would have cost too much to return it to Texas and so I do still use it rather than pay out another £100+ on the replacement (felt real good to get it for free so Kudos to T.M.E in Texas). I'll automate it once this one breaks ;o)
