Help me pick the best LED lamp from these three

[Hobbes]

.

North American lights only please, if you know of a good light that I missed please post and I'll add it to the list.

.

My Black Dog LED is only 2.5 years old but I get the feeling - smaller colas, airy, lower harvest weight - that the lamp is dimming.

So I'm looking for a new light and have the list down to 3 lamps - Mars Hydro FC 6500; Scorpion Rspec; Scorpion Diablo. All three look like great lights with the FC 6500 having the best PPFD chart, very even light over the canopy.

.

FC 6500: $1,110.; I can't get a pic of the light or it's PPFD chart to load here so here's the link: https://marshydroled.ca/collections/fc-series-led/products/mars-hydro-fc-6500

Scoprion Rspec: $1000: https://cdn.shopify.com/s/files/1/1538/8585/files/Scorpion_R_spec_PPFD.pdf?v=1601664425

Scorpion Diablo: $1300: no PPFD chart; https://cdn.shopify.com/s/files/1/1...on_Diablo_Manual_2021_online.pdf?v=1634667886

.

From looking at the PPFD charts the FC 6500 is the winner, but I don't know the pluses and minuses of the Quantum boards used in the Scorpions, please chip in if you have knowledge.

.

I read on the forum last week that the Scorpion Diablo has a hot spot, making the Rspec the better light. Anyone hear of this?

I'd go HLG all day. I've seen some sweet grows with Mars lights, but HLG is cheaper, here in the States, and you know you're getting top shelf everything Here is the ppfd chart for the Diablo

 

[GrassBurner]

Sorry, R Spec is cheaper*

Does Mars Hydro have independent ppfd tests done, or do they do it in house?

 

[Hobbes]

Good question, I'll find out.

 

[Rurumo]

Once my current grow is done, I'm going to put in my FC 6500 and see how it compares to the Fold-8 I'm running now. Those are all good lights Hobbes, I think you'll kill it with any of them.

North American lights only please

for a 4x4?

Thanks Rurumo, I'm interested in the result.

i would say get the white leds obviously but far reds, uva and/or uvb, maybe even some IRs would be what i would look for

I tracked down HLG, they have Light Laboratory do their testing. I'll keep digging for the Mars tester.

[Milky Weed]

Yeah my votes for HLG.

 

[Hobbes]

Thanks Milky!

 

[PSUAGRO.]

Out of your options listed, hlg , model depends on your budget.

You won't find a third party test on the Mars

Thanks PSUAGRO, I sent an email to Mars and I suspect that's what we'll hear.

Diablo scorpion all the way. Its the light black dog wished it was. Scorpion have a formfactor that eliminates the hotspot, dont worry about it. R-spec scorpion would work fine aswell but diablo has more blue range, goes down further in the blue spectrum than all other lights mentioned.

Thanks Rocket Soul, that was a great analysis!

Can you tell us more on eliminating the hotspot? How long ago; what is a form factor?
