Good synopsis! Thank you.

Frankenscorp. Love it. How much power?

The problem with this is that the detentes on the potentiometers can differ by quite a bit. I tested this on the 600Rspec I have, and the "halfway" click on the potentiometer was actually 80% of full power. The number of detentes also seem to differ on each pot as well. The 650R has several of them while the 600 only has one. The best way is to use a kill-a-watt meter and see how much power you're drawing at whatever position you are on the pot, compare that to how much power it draws when it's cranked up, and then use this to figure out roughly what your PPFD will be. When I measured 50% power draw on my kill-a-watt, the PPFD readings were damn near 50% of those taken at max (they were a little higher). It scales pretty reliably.

@@LEDGardener You can just produce your own pulse width modulation signal with an arduino or raspberry pi or whatever. Then you know exactly what percentage it is.

Oh absolutely - I’ve even got a video on doing exactly that, but he’s talking about the built-in pot which the vast majority will use.

Some of the clicks do nothing too. My 3rd click does nothing and last 2 do nothing. Kinda shoddy workmanship on such a high end light

Nice. I base this mostly on a conversation I had with HLG quite awhile back where they suggested it might be the case, but they were likely meaning on a larger scale. That being said, it looks like grandmasterlevel is doing a massive build with Scorpion Diablos in one of his rooms and it looks insane. Check out the video he posted most recently.

Please don't get the diablos!!!! Get the Scorpion rspec!!! The coverage area is much bigger and the light distribution if far more evenly distributed. I have the scorpion rspec and I'm running it at 32 inches at 100% . That will give you an idea of the power. I even had to add co2 to get the full benefits of this light. Get the scorpion rspec. You will need less lights and they will last longer. Can't say enough good about the scorpion rspec. Best light I've ever had by 100 miles.

It’s either Diablo or Rspec. Diablo uses QB648 boards with 648 white diodes per board plus 18 deep reds. Rspec boards are 288 white diodes per board plus the deep reds.

Alot more dioads on the more expensive one. Almost double witch means each one is driven much less and increase life span

You're going to be so happy with the scorpion Diablo. Not to mention you should be able to get a discount getting six units. You should be able to buy them for around $800 each. Very exciting system you got going on. That's a lot of work though I work 2 hours a day with 1:15x5 area and a few smaller veg rooms

9 scorpion diablos in a 15x15, 5x5 per light in flower and 6x6 in veg

Hell yeah.

Dang, great price

You can get new R specs for 800 shipped.

Will have to look into that, thanks

They’ll increase quite a bit.

Thank you for answer.I will use light in 4×4 space.

For sure. You’ll likely want to dim that thing down in a 4x4.

@@LEDGardener yes.what do you mean?

@@robertzancan9129 the Diablo has a dimmer dial

It’s a great value light.

Hah wrong channel?

It should,. Be easy when watering and make sure vent is on point

Not really

Yup, they’re absolute units!

What ia your brightness at?

@@Organicallyblunt I'm at 28 in full brightness for a 5x5 area and sometimes that's too bright for some strains. I've noticed that the ghost train Haze I have doesn't do good at 100% so I keep it at 80 to 90% at 28 in
