Both options are good for limited ceiling heights. Cost effectiveness going to the 120s/132s of course.

@Stephenj37826 I have used your online complaint form and no one has got back to me in a while now. The HLG 36 UVA light I purchased lost the first string of diodes on it. How do I get this replaced ? Send an email to warrantyhlg@gmail.com and we will get it replaced asap.

We will be introducing some uva/uvb strips but I can only guesstimate it will be 6 months from now. We met with Seoul and we are starting a design with them.

Yes we will be bringing those back as well as a veg specific "rspec" board.

Osram Osolon ran at 280ma or roughly 61% efficiency.

They I'll be added tomorrow to the site.

We will have this week. Waiting on heatsinks now.

Unfortunately, I had to take it seriously. Penetrator Quantum......... As many straight knock-offs of our product even by those, I would otherwise respect here kinda puts us on edge. https://www.icmag.com/ic/showthread.php?s=ca236426da995839a6c3c006045340b5&t=362254

What kinda name is that? She's calling us frauds and basically stealing our product names/descriptions....

We have a few in stock. Will add them to the website in a few days.

3500k + 660nm

No thermal interface material required.

Yes 3500k+660 is good for full cycle.

Not sure on the nichia but that size and wattage sounds like it. Our V1 qb96 is actually csp. The numbers just weren't quiet there. Improvements are being made.

At the end of the day no substrate will be king. Any material layer between the die and the pcb is a thermal barrier. Flip chip is great and eventually CSP will be the future soon.

I think he is going to run 1 plant per section. Just a guess.

We looked at the S5 3030 back in the 561C days when we originally designed the QB304. Osrams white weren't and still aren't there efficacy wise. They do have a flip chip 3030 coming from what I hear so it may be in direct competition to the lm301b. The Duris S5 reds are phosphorus converted red...

The ground is more to due with servicing the fixture. Anodized aluminum does not conduct electricity. The fixture must retain ground if the driver is removed incase some moron try's to remove the driver with it apparently still plugged in.... Also it's due to the voltage of the DC side being...

Yes sir
