Advice on 280-365nm smd's

Does anyone have any first hand experience with any of the newer uvb/uva smd's? For a few years now I have been keeping my eyes out for chips to fill out my shorter wavelengths. It's starting to look like there are definitely some reasonable options available now. I currently use the AgroMax Pure UV...

Dimming CC driver for mini herb garden

Hi all, I have been playing around with some extra parts I had laying around and built a tiny light array for an herb garden using 2 bridgelux strips and a little CC driver: Strips: (2x) BXEB-L0560Z-50S2000-C-C3 Driver: LPC-60-1400 It works great. The problem is that it is way too much light for the...

Re: Trouble expanding a previous build

All this confusion. Turns out DigiKey just sent me a faulty driver. Additionally, I don't think that the Bridgelux forward voltage curves are accurate on the data sheet. I hooked up 4 V/A panel meters to the array. 2 on the EBgen3 strips and 2 on the EB Thrive strips. As well as a lux meter on each ...

Re: Trouble expanding a previous build

Edit: I haven't tried only one type at a time because I only have 10 of the eb slim gen3's on hand. I thought only hooking up 10 strips to a 320 watt driver would burn something up. I am using an 18-3 extension cord I cut the ends off of with soldered/heat shrink connections so I don't think that's ...

Re: Trouble expanding a previous build

No, you're right, according to the datasheet this should run a lot more current. Possibilities: - Your connections are adding resistance to the circuit: have you got long cables with low gauge? This could mean that they can't quite get full 20V power. -Your driver might not be giving you full 20V. ...

Re: Trouble expanding a previous build

It's hard to say because you don't speak of which exact eb strips your using, but assuming you're using the 19ish V 2' version: since the driver only gives 20V your strips won't be able to draw more current. As current increase so does voltage requirement, and when you can't go any further then you...

Re: Strip recommendations for flower in 2021

I've been very happy with the BXEB-L0590U-40g1500-C-C3 strips. They're way more compact than the f-strips too. They also launched a hort specific line called Thrive. I ordered a bunch, but can't speak to their performance yet.

Trouble expanding a previous build

Hi all. I was hoping someone might help me get past this pickle I find myself in. A recent hurricane wrecked the driver (HLG-240h-24b) on one of the small arrays I built a year ago. I thought I'd take it as a sign that I should expand it, as well as play around with driving the existing 10 EB Strips...

Re: Low profile slim BXEB build finally finished

Hi, Was the 2 inch flat bar underneath each side just for extra heatsinking and support? Very nice and clean build. Those slims are looking slick. Cheers, Thanks! Are you referring to the flatbar mounted underneath the angle? It actually doesn't really serve a purpose, other than hiding the wagos w...

Re: Low profile slim BXEB build finally finished

I would recommend to use some acrylic covers in case you dont use sunglasses. Your eyes will thank you in the long run :D Big sheet of acrylic isnt that expensive. I'm using 3mm opal/translucent on all my lights with great success since they are hanging openly in rooms and i dont want to walk aroun...
