Has this company taken your money and seemingly disappeared from the face of the Earth? Edit:wording

The rack light that HLG is supposed to be coming out with was mentioned last in this post by Stephenj37826 I think, referred to as the HLG Scorpion. This light has been anticipated since earlier this year, and was expected to have been released already. Tough time to be releasing new products...

Man you just reminded me of this scene from Pulp Fiction. Time for a re-watch I believe.

Current and voltage figures will be different on the DC side. This can be useful info to have if you don't want to estimate it yourself.

That meter would go in between the plug and the driver on the input side. If the OP wants to see the drivers output they would want a DC meter (or a multimeter can be used to check voltage, current and such). The meters with built in shunts are easier to wire than the shunts that need to be...

The two lights being discussed are similar but not the same. https://www.quickbloomlights.com.au/products/hlg-100-with-blue-and-red-spectrum-diy-kit As you can see, the light from Quick Bloom Lights is a DIY kit. It uses a 188 diode board. 176 LM301H, 6 Osram 660nm deep red and 6 Osram 470nm...

Hey man, this is the spectrum shown for the HLG 100 V2 DIY Kit with blue and red monos (sold by Quickbloom Lights in Australia).

"And no matter top bin or low bin, when people can get nice yield, it is a nice bin." Is this the long awaited Mars Hydro mantra?

I was reading this link and noticed that the comparison chart for the HLG 600 R Spec and the HLG 550 R Spec states that Samsung LH351H are the 660nm diodes that are incorporated into the QB 288 R Spec boards that are used for each light. What does everyone think? Is HLG using LH351H for the...

The tent has reflective sides so the average PPFD will be higher. A majority of the photons that don't initially hit the plant canopy will strike the reflective surface and move back towards the plants. As opposed to open air, where any stray photons not initially directed to the canopy may end...

Maybe @count zero chose that driver for his white channel because of the recommendation by Led-Tech.De to use constant current power supplies to power their strips. Do you think Led-Tech.De is actually recommending against a constant voltage power source here such as the Mean Well LRS series...

Hey man I meant to pass this link on to you. Scroll down and you'll see a PPFD map for the HLG 320 watt kit. It doesn't say R-Spec so it's likely that the tested light was the previously released V2 model (with LM301B diodes and no Osram Oslon SSL 660nm diodes). Keep in mind that the 320 watt...

Where are you looking to buy that light from, Quick Bloom Lights in Australia? And is that light a DIY kit? Here in the USA, HLG is currently selling the HLG 650R. The Diablo board DIY kits are discontinued (the boards are still available through at least one reseller) due to the known board...

Depending on what price you find the individual parts for, you could save 50 dollars or a little more. If you do end up going the HLG route, remember the 10% off code RIU10 (DIY10 works as well) that @PadawanWarrior mentioned.

Multiply the wattage x system efficacy to get the lights PPF output. 320 watts x 2.63 µmol/J = 841.6 µmol/second for the 320 watt R-Spec kit. The PPF figure is actually a little higher as Horticulture Lighting Group says that kit will top out at 340 watts.

The 320 watt R-Spec kit with 3 boards is also driven a little softer (1750mA vs. 2100mA I believe) than the 260 watt kit with 2 boards. So in addition to higher Photosynthetic photon flux output, the system efficacy is slightly higher with the 320 watt kit.

Are you thinking of stipules?

You've misread the chart you posted. If the OP is trying to follow VPD (easier said than done in some situations), .6-1.0 kPa would be a better range to aim for with their vegging plant.

The drivers that I own are Mean Well HLG so I have no personal experience with them. I can say they look like a high quality product with a solid warranty and more programmability than most Mean Well drivers, if what you are getting is an authentic Inventronics driver. Horticulture Lighting...

The 12,373 lumens @ 120 volts AC is a typographical error. Whether the 121,000 lumens plus figures are accurate I can't say for certain, but the total lumens output of the fixture will be much closer to the higher lumens figure across all compatible input voltages. The error just shows that...
