Does the artwork help increase the yield?!?!
Sort of like classical music or talking to your plants can make them happier?![]()
Nope that's left over it was a quick reno lol hoping to be in a new building next yr

10a / 7 strips = 1430ma (and the A version may have even more than 10a!)
maximum drive current of the strips= 1400ma
So you need to dim the current output of the driver! This way maximum output would be around 460w (2x 7x 1400ma*33v). Driver current limit needs to be 7x1400=9800ma to be safe.
Saw graying.geeks measurements/thread and it made sense to me. The center of his fixture had too much overlap(for lack of a better word), so he adjusted spacing and achieved better spread. I'd be interested in seeing evidence of Danielsons refute.
Not to piss in your Cheerios mate, but some of us have the "B" driver and just dim the lamps down rather than raise them up. Just saying...more than one way to do it.![]()
Due to the "logarithmic" spread you lower the hotspot in the middle and increase the intensity at the edges. The result is a more homogeneous illumination and in the best case you can hang the lamp lower, so that the light can be used better and the intensity can be increased overall.
Instead of 1000 μmol in the middle and 400 at the edges at 16" you could get 1000 μmol in the middle and 800 at the edge at 12".
What do you think would yield better?
Of course, if you keep them hanging at the same height, you will not notice much difference. But if you take a lux meter and hang both lamps so that they measure for example 1000μmol in the middle, you will notice that the logarithmically distributed strips will hang lower and the sides will get much more light, as with the other higher hanging lamp.
If you have the two lights, try it. It works this way.

But I have two of these drivers. And I can buy more strips and double this light if need be View attachment 4053258
PS I left the light on lowest dims. And left it high because it's all new. and I'm being safe...
Lights on the table behind are two mars pro series 2 epistar 160s
PS the strips are mix of 3000k and 5000k
I think the current is measured in series, if you want to know the overall current output you just need to put the multi meter right behind the driver (in series!).Well the strips are 2 ft it sais 700ma on digi key.. Or is that just the avg and 1400 is the max?
OK I got my multi meter. Where do I put the positve and negative to be able to read how much I'm adjusting the current? Just + and - on one of the mini cobs on the strip?
Right, and this has no effect on the way I grow. In principle it does have an effect but for many people it's absolutely irrelevant. All the power to ya if spreading your strips in the center increases your yield! I'm sure it would be interesting to see the difference in results, or lack thereof.
OK as a fast fix IL be putting the second driver on and I have two extra strips on hand IL throw in the mix.
X2 - Hlg240h-24a with 8 two ft strips
That should throw some light haha.
My question is.. Can I use the same power cord and wago two drivers into one power cord ?
Or make a new cordView attachment 4053429
Well, I think you know that you can only raise the brightness in the middle to a certain point, and in addition you get bleaching. It's about avoiding this hotspot and you can do that by optimizing the gaps between the stripes.
You can run both drivers to a junction box where the - and + and ground wire will all meet up in wago's. Don't forget to run a separate piece of wire from the 'ground' wago and screw the other end onto your frame. Run the power cord into the box and connect the wires to the same wagos and you're done. I like to add a switch so I can manually turn my light on or off whenever I want. You do everything exactly the same except you run your - wire from the power cord onto one pole of the switch and then run a short piece of wire from the second pole to your - wago and you're done.

Made two sets of 7 and keeping it at25% until I get a chance to test it tomorrow.
I turned it up to max for a second and yeah it's 400w bright haha.
Does the meanwell driver have a limiter to prevent me from roasting these lights if I were to leave it on full blast?
