Are HLG test results wrong? HLG 350R led grow light PAR test 

I second that sentiment

If anyone wants to thank him enough, Buy his damn light

It's pretty misleading to use an integrated sphere and advertise the efficiency as that result. No one is growing in an integrated sphere so, as we see from Shane's test, there's a big difference between HLG's advertising and what you're getting.

Makes alot of sense 👌

I have been dreaming of a comparison of this hlg 350r vs the electric sky es 300. They both draw about 330 watts from wall. So it’s perfect comparison.

Yeah QBs tend to have pretty bad hotspots.

@@HAPPYHERBS1 I literally had it at 50=percent and 20" away and leaves were curling and loosing chlorophyll. Strain dependant I'm sure, I have it in an open room set-up at the moment. I am thinking of putting it in the 3x5 tent. Instead

love mine also. I have 4 in a 4x8. They go hard

@@Prairie_Plant_Daddy nice set-up. I'm all over the place with lights at the moment. Optic led is my primary lights, but I had such good results with the 100 watt v2 rspec that I went and bought this light to try. are you intrested in getting another one? As much as I like the light I want the 650s from Optic.

@@HAPPYHERBS1 have it in a 5x5 and it's powerful. Had to raise it up more and I only run it at about 60 percent. It's alot warmer than I expected, wished I could put the driver outside the tent.

I have noticed with HLG some of there tests with meanwell drivers had increased efficiency over the inventronics drivers.

Nice. That's an awesome analogy you got there and I ain't even much of a car guy

100percent in regards to us growing In tents and not that round sphere. His calculations are more practical

You dont grow in a sphere man ? Its 2021 dammit! 😂

Because it’s an industry standard test. In a lab. With no variables. I agree though that it’s sort of a dumb test for grow lights to be tested in a sphere, but it’s also dumb that everyone tests lights in boxes with silver lined walls. White reflects light much better, and would yield better test results.

@@tombryant4518 you so right 👍🏽

@@tombryant4518 White does NOT reflect better than smooth or textured mylar. You're dead wrong. Shane himself had proven this.

@@MrE1981 Sure bud. There’s all kinds of scientific proof out there that says I’m correct.

Also Par meters are not nearly 100% accurate as they do not measure all wavelengths in the 400-700 range 100% accurately.

you can see him measuring whit 4 sides in other vids so just removed for the video i guess

Yes all four mylar walls were in place for the test

what the hell are you smoking

HLG stuck in a time machine? They are the original “quantum board”. Fluence and HLG are the original high ppfd led manufacturers of grow lights. There were a few other guys but they really started the Samsung Osram craze. HLG uses some of the best products on the market. They also have hands down some of the best customer service ever. You know when you buy them you are getting real Samsung diodes. I bought a knock off “quantum board” and they aren’t Samsung diodes at all.

​@@ModifiedTacoYes. They even patented the term Quantum Board. Definitely one of the original high ppfd LED companies. Fluence, as well. First "bar" light I saw at the Hydro store. "There from a local manufacturer", I was told. They are from the Austin, TX, area, but were never really "pushed" here, at all..?! IDK if they're still here..?! I forgot I watched this, and commented, lol. "HLG stuck in a time machine" wasn't meant as an insult, just that Quantum Boards haven't changed much. No Meanwell Driver above, if at all anymore (Still Great drivers. I think Meanwell were just one of the first made for grow lights..?!)🤔. The newer Diablo fixtures got me thinking Quantum Boards aren't the future, and the "bar lights" had a better light spread around the canopy, even though the corners are still low. Then GML comes out with their Tarantula. "A Diablo copy", my first reaction. Until seeing Shane's latest videos testing it. 8 quantum type boards, instead of 6, like HLG's..?! Best efficiency and canopy spread he's ever tested, even in the corners! HLG could have designed these, as they're based on their Diablo, but didn't, sadly. I would have loved it if HLG had figured out this simple change in design. They've always had excellent customer service, especially if there's any problems, which are rare. I know someone with their newest 350W fixture, like above. The driver failed. They immediately sent him a new driver, overnight, then asked for the failed driver to be sent back. Usually, a company would want the old driver first, then try to repair it, etc. HLG has always been tops in this area!👍💯✌️

​@@jacobstanfill9538"The Devil's lettuce", of course. Hellfire!😄😄

This will do it, you will get an average PAR of 1,000µmols in a 2x3: migrolight.com/collections/all/products/migro-aray-3-270w

It's coming soon. I have the new one here ready for testing.

Its the Asensetek Passport Spectradiometer with SGAL app

All leds have a Flickr just like hps. Just depends if the Camara and fixture happen to sync .....

thats 5000k of white with red spectrum brining the color temp down to 4500k

Yes exactly. Even if he raised the light here instead of focusing on 1000 in the center he could have raised it until it hit 800 in the center and that would have improved the overall coverage where you could actually flower the edges.

Yeah, apart from like 5 other companies, best light 👌

sphere testing is industry standard

Just watched it

@@cory4419 Were at?

yes

Lmao I mean why the hell would you have your plants touching the light when it’s recommended to keep them 15” to 24” away from the light…

@@ronquando3088 had to leave town for few days. They grew over 18 inches in 4 days. Didn't expect that to happen.

I have over 10+ fixtures, some of wich are 4 years old. Only one lil cluster has fried out of all those and it was a group of 6 on my lumatek attis.

Intensity drop is nothing like how fast a HPS will degrades, plus it's a higher quality spectrum, maybe look in to them more.

@@HAPPYHERBS1 are you happy with Lumatek? I am about to order The Photontek X6000.

That's why you avoid sketchy brands like Viparspectra & Spider Farmer who use cheap Chinese reds & then don't tell their customers what they're buying. As long as the boards use something decent like Osram SSL's or Samsung 351's they're good, reliable chips with higher efficiency than the whites. If they won't tell you what the red LED's are then they're using junk chips, they're the ones that fail.

@@RocketNothing spiderfarmer and viparspectra are using osram reds. Viparspectra makes a version w lesser diodes but its less money too. There are not even that many reds on them anyway.

I rock a scorpion diablo in a 5x5 and it's perfect.

With 2 - 350s you will be able to spread exactly how you want to spread them. I also believe there may be a slight efficiency bump using multiple smaller drivers instead of 1 big one. Probably a miniscule bump, but a bump nonetheless.

If you run two lights you will have flexibility with hanging height for different strains or phenos.

This only really has good coverage in a 2x4, so 4x4 would be good for 2 but the scorp is made for a 5x5, also its 6 vs 4 boards so will give you much better coverage.

Go with the 350's. I'm rocking 4 in a 4x8 and they are killing it wall to wall

I know some people than can crush a 4x4 or a 4x8 tent that are crushing it better than they could with a room twice as big. You’re right about the tent having advantages sometimes depending on your environment.

What do u do for hanging height?

Nope, nowhere near enough coverage for a 4x4, maybe for a mother and clone tent, defo a 2x4 or 3x3 light tho.

@@HAPPYHERBS1 A really nice 2x4 light. But super expensive!

Correct.... But regulatory bodies will not recognize Shane's methods. Integrating sphere testing is the most precise method of measuring light coming from a fixture and is what DLC currently uses to qualify a fixture. Shane's trading is excellent but par meter used , reflecting material efficacy, and measuring standards can and will affect the results. So the industry needs a standardized testing method that no matter where the fixture is sent it is in a lab setting.....

That's what I did lol

That could easily be changed by adjusting the hanging height. 15” is too close if you ask me depending on your environment. 18” to 24” away would fix those edges. And still keep the center in good ppf range

In your opinion is the chilled light worth the extra 250 dollars? Their new lights are 1600! Wth

@@jhonwayne1003 I think they are I've had em all, grown w em all. hlg ,growers choice ,gavita, all the big names. in actual real world grows the chilled are so over built they run so dam cool it's almost unreal. I won't run nothing but the chilled grow craft x6 now. There built to be commercial grade the heat sinks are insanely over done.

@@smokey-qq6hd I was not prepared when I saw a 1600 dollar price tag for the new ones. So let’s just say im running in a 2x4 closet. Vented to attic pulling cool air from room. Is the older version worth investing in?

@@jhonwayne1003 the x 3 is the one you want for a 2 x 4 closet. U won't be disappointed .

@@jhonwayne1003 get the chilled grow craft x3. That's all you can fit for wattage in a 2x4 . Those are not as expensive

I think it was just a little oversized area , in a 4x2 the numbers would be crazy all across

@@GLClarity yeah if you take the outer measurement away it would be better but still nothing on a light bar giving a whole canopy within 50/75 par across the board. Trade of is less light pen but depends how you grow wich is best for you.

@@GLClarity They would be good but I can run two Viperspectra P1500s in a 2x4 for $180 US. Not as quite as good but $370 less money.

@@HAPPYHERBS1 it would be better then just taking away the outer layer the closer walls would reflect the light and give higher numbers across the canopy … not saying its a perfect light or that i would buy it over competitors just that it would do better in a smaller area

@@gregkramer5588 thats true … im not advocating the purchase of the light just saying it was in a oversized test area ( in my opinion) i actually have hlg scorpion diablo and mars hydro bar style and prefer the cheaper bar style but there both good when used in the right footprint . Like you said hlg slightly better but much higher price my comment is only on the space it was tested in
