alternative to HLG's quantom boards... the supplier!

If you want you can get those Meanwell's with the potentiometer inside if you're going to individually adjust. You can also parallell a bunch of the 0-10s in to one pot. I believe the 0-10 side only drives 100ua continuous so if you had 10 of them its 1ma which is not very much on that big pot. Without knowing a part number, your pot is probably good for 50ma.

 

I haven’t personally used the cv hlg drivers, but I am starting to think, these could be a good answer to lower voltage, supplemental lighting.

I like the external potentiometer myself. I can run the lines as long as I need to adjust power.

With the setup I’m working on, getting to the onboard driver adjustments wouldn’t work. It wouldn’t be a deal killer, but, it wouldn’t be as convenient as having adjustments available at the door of the tent.

Food for thought for anyone choosing between the two drivers

 

What’s going on here?

 

Bigclive's new video (caught the name in the snap)
that light is from Samsung, not sure what diodes though...

lookin good ! cant wait for my 240W to arrive next week! gonna order more if it lives up to my expectations..

 

Kingbrite?

I setup some of their 3500k + 660nm for a friend. I was happy with their craftsmanship and service

 

that is reassuring ,thank you, i had heard some good things. and am eagerly awaiting my 3000k + 660nm!

 

looks good man! nothing like that feeling of getting brand new lights.

 

Hi

Yes they are from kingbrite and they do look nice and draw 305w from the socket full blast and at minimum 5w, the 2year warranty on them made me buy this specific set.
Now the proof will be in the pudding, how well the plants grow.

 

So about potentiometers, if I am understanding correctly it's a transistor and creates heat. Is it inefficient old tech?
If the focus is on efficiency, is there any reason not to use PWM?
Been researching how best to program multiples of boards/drivers to perform sunrise / sunset and various dimming controls. Can it be this easy?

 

i

i cant handle the way this guy say multimeter lol wtf

 

very interesting video none the less. i will be looking into some PWM dimmers now haha!

 

Haven't grown yet, but I am looking into getting lights. I've read through this thread quite a bit.
What are everyone's opinions on this? Seems like a good deal.

That would definitely work and is not a bad deal. I think their are better deals to be had if you go back on this thread.

 

maybe go for 2 of the 240W units for more versatility ! you would be better off with two of these probably,, ask them for a discount.. im dealing with vivi, she is offering me this exact light for 117 usd, so two of them for 234 plus shipping seems like a way better deal than the one you posted !

if you dont want the added 660nm reds, im sure they would go cheaper than 117 per unit.

 

Appreciate you bro. Thank you.
