could 3 hlg550s replace 2 1000w gavitas for a 4x8?You're either completely blind or you're not even reading the posts on this thread before replying...No one, not even once, said 1x 1000w HPS could hang with 2x HLG-550s. Your statements are based on nothing. You just randomly come up with stuff like, "..so 500-550w quantum should get you pretty close". I've posted the data. Observe it, note the differences. You've got graphs for 1000w HPS in a 4x4 reflective area and the HLG-550 in a 4x4 reflective area, in this very thread. There is no debate. The HLG-550 has 30% less output over a 4x4 space than 1000w HPS, and nearly the same light uniformity. I've done the tests, you have not.
I've already stated I'm a proponent for LED. Are you reading my posts? I don't believe in HLG's claims that they've succeeded 1000w HPS with 50% less power draw. That's all.
I've literally proved it in this thread. The HLG-550 is inferior to 1000w HPS in terms of light output. That is a 100% fact, which you can verify yourself by purchasing a quantum sensor, 1000w setup, and conducting your own photometric uniformity test. Until you've done that, stop posting on this topic. No one needs the opinion of someone who just pulls random data/information out of their ass.

hi guy's I have just purchased a hlg 550 and I'm sure it's performance to what I have seen is closer to a 315w cmh or a 400w hps. just you watch soon they will have reflector wings to control light spread. I might fabricate mine and let you know. at the end of the day do what helps you out the most. in using mine for veg at the moment but use cmh hps and led side lights for flowering works a treat.

A hlg 550 will EASILY beat a 400w hps light.. its more the equivalent of a 800w hps - just for the record.. no they dont need reflector wing..hlg used to sale a version with reflector but didnt last very long. Reflector are used with HpS because the light is 360 degrees while LED in the HLG products are 120 degrees. Ive seen some use lenses but not many and Id say its for some very specific set up or needs that it has been done

depends where you are in the world maybe some people rely on the heat from a hps.... no need for the tense abrupt reply. like I said DO WHATEVER HELPS YOU OUT THE MOST....... omg hps emit 360° of LIGHT!!!!! I've only been using them since 2002 holy mother of god next you'll be trying to tell me you can grow indoors with these spectrum emitting glass tubes that I mistake for dildo's....

I'm a skeptic about a lot of what I read here and grow with HID but if I was to get a 550 hlg I'd give it some time before judging it.

Relax bud didnt mean to be mean to you
What have you seen, where have you seen that? I was just stating that you were incorrect and comparing a hlg550 to a 400whps doesnt even make any sense.. there is tons and tons of thread that can prove you wromg.. if you really had taken the time to “see”..
Just trying to save you some time, it had existed and been tested and unless some specific needs 99% of grower would not benefits from reflector wings.. you want to spend your time and money to try it out on your own fine.. your choice but im just giving you advice and if you cant take it then might as well not come talk to us on a forum which should be open minded..
All good bro move on

Yeah no doubt with the very popular blurple light generation few years ago its normal to be skeptical about LED but comparing a blurple light to a samsung top of the line efficient LED found in the hlg550 is a complete different story.. I can understand skeptisism but saying that 500w+ of efficient light would have similar perfomance of a 400w hps. That is just misinformation in my opinion..

don't get me wrong I'm all for led. helps out with heat in summer. cuts bills and buying bulbs every couple of months. once I've used mine for vegging I'll pop it in for flowering and i will soon see.

I agree on the blurple bit especially with viparspectra, ok for veg but not enough red for flowering.

I never used a LED but my 400 watt HPS has grown the biggest, densest buds I have ever seen. I have grown many plants in full sun too. Just my two.

Dont expect a 1000w DE HPS replacement but a hlg 550 is worth about a 8-850w hps in terms of power/yield... if you like to diy look into samsung strips which use the same LED diodes than the hlg product.. anyhow I suggest you hop on the LED section on this forum.. LOTS and LOTS of info and builds and so on.. i pulled 20oz in a 4x4 with a chinese knock off the hlg550 not bad I think

the quantum boards with the mean well drivers? seen them on alibaba.com I had a quote for £200 includes all costs delivered to my door. they are getting bigger I noticed a 804 board with a 600w driver on there yesterday. think they said there was x2 boards with 804 led's on them. 1608 led's??? what would that even match up to regarding hps pushing new territory 1000w +?
Even veg Viparspectra is no good. 600 HPS smashes my Viparspectra 900 during veg. Not to even mention flower.
I'm not at all opposed to LED. Infact i believe its the future.
But there's way too many bullshit comparisons by LED manufacturers.
The reality is, if someone is going headfirst into growing, and has to choose a light. Then the reliability of HID is extremely hard to beat. Brand to brand.
But the reliability, and price of LED is still outrageous imvho. There is so much variety in lights watt for watt, brand to brand.
It's a consumer nightmare.

Cost me 400usd for 4 boards with heatsink and meanwell drivers delivered to my door in 2 days from china.. still need to be careful when buying on alibaba as many use cheaper or less efficient diodes on their boards althought in some cases they look almost identical to the real one.. (lm561c s6, lm561 s5 or some use lm561b/b+ model - seller will tell you they use top model but the reality is its not always the case)
the bigger boards have been there for some time someone tested 2 at different power and height and did a par map @Moflow ..the thing with those samsung diodes is harder you run them less efficient they become they can go up to 200-220lm/w if ran very soft while hps is about 110lm/w if im not mistaken.. but most people using the samsung diodes are probably running them at around 160-170lm/w so about 60% more light than HPS for the same power but could go up to 100%.. at a certain point cost comes into play for many.. whats good with quantum boards is also the fact that the light has a better spread so less hot zone..

Yes for blurple light light vipar you need to look at true wattage or actual wattage from the wall so a vipar900 is probably around 400w at the wall which would mean equivalent to a 400hps this is why your 600w hps kills it no doubt about it

your right there it is a nightmare. I remember the very first great big huge metal ballast's with vents on the sides.... now the tiny little digital beasts run cooler and more efficient. I never even attempted flowering with my viper's...they are side lights when required.... hopefully the 550 will come up good when I use it for flowering. like you said 600w hps has been heavily relied on by generations of new growers.
Yes correct. I think its draw is 389 watts. Could be 480 though. I can't remember.
But in all honesty i resorted to a 600watt HPS with a dimmer.
First grow after the Viparspectra I only used the HPS at 400watts, because i was new to indoor growing.
The difference in veg, and bloom at 400 was obvious. I'd say i had 20% more plant matter overall, for the same amount of time.
Its the honest truth.
I hope so too.
I'm of the opinion HLG sell great quality lights regardless.
My belief is we all need to stop comparing LED to HID. Manufacturers need to stop using the words "better than". It drives me crazy lol.
Personally HID saves me money on heating.
But if there was a light that could perform as well as my HPS under ideal temps. Then an LED makes perfect sense for myself in the hot summer. It may even improve on yield. But during winter, i have my doubts...besides the cost.
Let us all know how the HLG550 goes. Even pm me.
Because a HLG550 would be a perfect replacement in my 4x4, for the summer.
Best of luck with the grow. Hope it's a good'n.

I have put 2 clones aside from the same mother vegged for 4 weeks 18l pot coco same nutes and i'll compare against the 600 and the hlg 550. this is one of the ladies from the 600w with voter's as side lights. I'll keep it even and this one in with the hlg too. it is hot at the moment but temps stable at 28°c lights on and 20°c lights off. but it did creep up to 31°c the others week. I'll post results in 4 weeks for this one then side by side in a few months. this is a grapefruit strainViceman666

And if you are in europe because I saw £ sign somewhere you can also look at the hlg600 sold by an authorized retailer of HLG in europe and you get a bit more wattage then the 550 may end up cheaper too if not too late lol
And finally because the HLG product are more efficient and produce less heat you want to run your room a bit more hot than hps to get a good 82F leaf temp (close to 28C) for maximum photosynthesis..
Im not too technical in knowledge there is tons of expert and studies, real life example in the LED section of this forum
