Now that's an absolutely dope measuring system. I'm impressed.

You just took it to a WHOLE new level with the gantry. Like what?!?! Your work is incredible as always.

Hell ya, great job. Been waiting for a good comparison of these two beasts of lights. Love they system you built.

Now this was the kind of testing and info i was looking for

Thanks for the content man , awesome , my DIY light is running about 40°C and I was very worry about it , seen how much hot lights like these HLG run, makes me more calm. Thanks again .

Just the video I was looking for! Great job!

Great job bro. Super clear, articulate, and well composed video. Your engineering skills are impressive as hell. Keep up the good work dude 👌🏽

I love your new measurement device!! great stuff,thanks for raising the bar as high as it can go!!! your information is integral for our industry to make informed purchasing decisions. If you have any extra lights you need to let go to free up some extra space in your lab, please feel free to send one my way if you don't mind,lol, I'm sure you have a warehouse full by now! lol! love your channel, thanks again!!! kudos!!!

Impressive, professional, just an outstanding informative video backed by science. Nice job and great effort.

All I can say is wow and I'm blown away by your work. HLG is over priced in my view, but your testing is beyond anything I've ever seen. Thank You and great job.

Your measuring tool is beyond incredible and so accurate! Your very smart! Thanks for the information on these two lights id love either one of them!

The 600rspec is the truth! Ran 2 over a 5×10 canopy. Also had 3 plants outside the 5×10 area even those 3 produced rock hard nugs.👍🏽

Great video ! Thank you 🙏. Very well done. Great data results and comparison. I really do like my 650r

the 600 r spec is on even better sale now. not sure how long i just picked one up for 700 shipped directly from hlg. the 650r is still 1100. i really want the 650r but there is a considerable price difference between the two. the 600 r spec will be replacing a 400w hps so its going to be a huge major upgrade for me!

Really nice mesurement set up!!

Just picked up a Diablo for their Black Friday deal.. will be unboxing it this weekend.. Thank you for this comparison..

Excellent comparison and numbers, plus your new PPFD measuring robotics just left everyone else in this review space in the dust.

Liked & subscribed, great work I am highly impressed. HLG American made with a 3 year warranty. Worth every penny

Impressive setup, nice man!

Great video, highly detailed as usual. I am currently trying to automate my farm, and I am finding it very challenging!

I don’t usually like videos like this because it clogs up my music, but this video is top notch. Appreciate the work you put into this so us “tomato” growers can benefit

More please and thank you very much.

I completely agree with everyone else. Genuinely impressed on that level of mind that was used to produce this project.

Great video! i am interested in getting the 600 R Spec as it is on sale. I understand that this light is a full cycle light, but lacking in blue light, so what blue light would be best to supplement along with the 600 R spec for a full cycle grow? Thank you!

Mine are 2 years old now, love them. Well worth the money 💰.

This man needs more subs

I’m very happy I found this video. I’m looking to light a 6x12 area and wanna see if I should do 4 of one over the other

Hey man, Very good job. I have this light and its so good. Just watch these vids to confirm I made right call and spent the cash

Awesome video man! You sold me on the 600 R it’s 699 right now :)

Well damn. This guy is good. Once I saw his measuring device I subscribed lol

Excellent video man well put together going to have to get that deal

This testing unit made me laugh out loud when I first saw it. Not in a bad way either. This is pure GENIUS.

Would you use these lights for a scrog grow or more of a bush style grow? Are they bettered suited for one over the other? For price difference and stats I think I’m leaning towards the 600. I can buy four for the price of 3 of the 650. Is it really worth that 100? Is it going to change yield that much?

Great vid~Great info. 🤜🏼🤛🏼

Hey can you do both of the hlg Scorpion compare to each other in a 5x5. Really great video!!!

Nice video. Thanks for the info 👊

Can you share the T-slot you use and other part ? Huge fan of your over Engineering approach :) best

As always, outstanding.

Exelent work 👍✌️

50 degrees C on top? That's pretty hot....but question please! Say an average decent sweet spot room temp as you say 25 degrees. How hots the lights underneath? the chips. Pretty hot or alot cooler than an open 600w HPS? Or would you say as hot as av average air cooled HPS.?

I see lights that say 1648 3000k + 800 6500k but can’t find anyway to get the kelvin out of that.Wouldn’t it be better to get a full 2700k or 3000k for flower and 4000k 4500k or more for veg instead of full spectrum?

There nice lights, very pricey though.. loving your testing method

Super nice video. Just fantastic. Thank you. Have you checked out the ascend series by hortilux?

Is the hlg 600 better than the hlg 550? I'm confused if so I want one

Is it ok for the light to run that hot 24 hours a day ? Also thank you for such an amazing video. I would love to know of the gavita 6/750 comparison to the gavita 1000watt

Oh man you gotta pair up with Migro and Dr. Coco. You three together would make the ultimate light testing environment!

Could you see if Spider Farmer would be willing to have their SF-4000 tested? I’ve been looking for comparisons but there aren’t many and this is the most informative/ accurate test I’ve seen. Keep it up!

Dude ur the man I've watched every video on utube you killed it ...

you sir are a scholar and a gentleman.

Which version of the light 650R is better - 4000K+660nm or 3000K/5000K+660nm?

Any chance you can do this test with a Philips Master 3100K GreenPower Elite 315w CMH?

Fantastic test, pretty much setting a new benchmark! Any possible retesting with modifications to spread the the boards out further? This middle hot spot most lights exhibit is really not very practical unless you are growing a single tree, with a lot of ceiling height at that. It would be nice to see where the boards have to be located to get near perfect coverage and would also allow the fixture to be lowered no doubt. Thanks for a great video, its innovators like yourself that really pull the weight in many social media platforms.

Liked and subscribed. Would the HLG 650R Diablo be good for a 4 by 4 tent?

What spectrums are they?

For the price of those lights you would think they wouldn't look so cheap made like they do plus the drivers are not removable and 140° degrees is way too hot. I would go with Chilled Growcraft lights or Photontek over HLG every time. (Awesome review and great video)

wanted to ask your opinion on which light would be better for a 5x5, the 600Rspec or the SpiderFarmer SF-7000

How warm does the driver case really get?

Also what if you got a 15% discount for the 650r?would you still go with the 600r?

Can you use a 600r and two best a 2000 elt in a 5x5 tent

What do you think about Kingbrite quantum boards? Congratulations for your videos, always amazing!!!!

great job

Amazing. You should test the optic 8+ next gen and slim 650s

My 600 rspec dimmer has a indent approx half way. I assumed that's a 50% mark but was told it may be closer to 80%. Any chance you can let me know for sure? My 600 came with the inventronics driver.

great video. Are you doing one on the Scorpion Diablo? Also I use a 4x4 tent, would these be overkill then?

Can you compare 650R Diablo and Scorpion Diablo?

Great video I own both lights an was curious bout this

are these boards waterproof at all?

Amazing man ! I have the diablo boards there awesome. Btw where is part 5 on the garden !! I need help with the node red lol

Have you tested the scorpion? As a growtent home grower would you want 650 Diablo or scorpion

Pretty sweet automation btw I am a software engineer by day and have considered using some arduino for various things revolving around watering.

Would it be possible for you to do the same thing with the scorpion

great video, how do you think the scorpion r spec fares against the scorpion Diablo

Would the canopy penetration be less on the diablo board?

Super smart dude wow 👏 👌 let me ask a question im looking at 2 lights a California lightworks Solar Extreme 500 or a 330 watt Demon Board ?? Help a brother out Canna Fam

Thanks bro u saved me so much money

u saved me so much money thanks

The fuck bro! Your a genius!! Keep these vids coming man. "I 3d printed my own automated ppfd reader " lol I love it!! I'd love to see you compare the 650r spec to a new 720w bava green!

What the fuck did I just watch? Awesome measuring tool... WOW. Great video!!!

Man, i was starting to tink that you got the corona or something since there where no new videos.. glad you are ok and i can now see why(that measuring system is sick and must have taken a LOT of your time), BUT i am begging you to continue the automation series.. i invested and brought all the components and started to build and install but i am now stuck since i am clearly not intelligent enough to do it by myself.. XD so again, i am begging you.. continue the automation series.. let's up this comment so LedGardeneer sees this!

only problem with starting with the best light... Few manufacturers are going to want to put their light up against it... Amazing measurement system though, I'd love to see the new nanolux setup in this...

I got the 600 r spec for my 4x4. Overkill?

Is there 4000K or 3000K+5000K?

10\10 vid

Would you recommend the 600 for a 4x4 or would that be overkill?

Thank lot s bro....

I just got the 600R and it's incredible. But let me tell you what that Diablo is a monster. My buddy Rick at our grow store fired it up and he warned me before hand watch my eye. That thing literally hurt my eyes just turning it on in a big room and turning it up. Thankfully that thing comes with some glasses. It is a Bodacious light

This light or the sf-4000

put the 550 v2 spec with uv strip 1400 dollars plus tax against gavita630 watt cmh double ended light and the wnner is gavita cmh 700 dollar bigger buds awesome light penetration got good solid bottom buds unlike the hlg leds which were very poor quality bottoms. and smaller tops. the quality of the cmh were better turps under the microscope the cmh had more crystal and were amber faster. could have let the hlg go for another 10 days easy. but im into getting 6 a year on each side not 4 or 5 crops, in all the hlg are going for sale sadly i also bought to test out their hlg 1100 dollar veg light which is crap also take care love your channel.

Genius 👍

Get on that patent ASAP bro!

Is the 650 a lot better? Or only a bit better

To hell with the light what about the measuring device?

They updated the 600rspec recently so you can't get the one in this video anymore. They change the spectrum from originally having all 3500k with 660nm too now having 3k and 5k mixed with 660nm. HLG claims there updated version of the rspec is even better. So the new rspec should have a little better numbers then this old version.

Just got the 600r thanks for video the 650 was tempting but i rather save the 300-400$ and the 600r is bright af!

I just won the 650R Diablo in a raffle last weekend from a $5 raffle ticket!

How do we get in touch.

I have the 650r well worth it your video helped me pick my light i had got some spider farmer and was not happy with the coverage i am replacing 1000w de fixtures and the spider farmers would take more than 1 sf 4000 per plant and my plants still wanted more light so i ordered more lol well i got mix matching lights with different chip lay out and. well a company with no phone number and oh so sorry we send in a month right parts you fix we give deal crap is for suckers and something a reputable company would never do in the first place. And at 600 a light total crap. just so people looking for a light spider farm finds growers on youtube asks them to use the light sends them a amazon gift card number for lights they get light leave review like they paid for it make a video you get played into think they are a real honest opinions of the light they are paid to sucker you. if you have never grow or used a good light you don't know how bad you are getting played.

I think I have to go with the Rspec. I'm buying a few and don't think it's worth the extra cost for me.

That's a lot of heat.
