This light works great and added about $12 to my monthly electricity bill on an 18/6 schedule. In my opinion, the absolute smallest area this light should be used in is a 4x4 tent but I would consider using it to veg as much as an 8x8 area. You might need to up your nutrients to compensate for how powerful this light is.
I got this light when I just started and have since moved on to the fluence. However, i still use the sp everyday in my grow and it performs perfectly. If you 6 or 7 of these side x side. It would be exactly the same as the fluence. So its basically like getting a piece of the pie without buying the whole thing. If that helps...
I pickup 2 of these lights for my 4ft x 8ft tent. Building the lights was straight forward and easy I felt. They are heavier than what I thought but definitely a quality unit.
I have them 4 stars because there are a few things I feel are overlooked.
1. They produce A LOT of heat for an LED light. I had to upgrade my intake/exhaust in my tent to keep up.
2. HLG should absolutely include a potentiometer with the light WITH WIRING INSTRUCTIONS! I looked everywhere for a wiring diagram and couldn't find one and eventually pauses the video on this page 45x to figure it out. (Picture included for others that may need it)
Overall this is an insanely bright light that is probably overkill for most but worth every penny!
(Also included power draw for 2x lights)
what fast service ordered late friday nite light delivered next thrusday and thanks mars hydro for a great light and listening to customers and extendong the driver cable thanks for everyyhing
First complete grow underway and vegetation has been flawless. I can run the r-spec a little lower to the canopy and the plants seem to prefer this over the non rspec 260v2. They’re staying nice and green, with tight node spacing and a symmetrical canopy. Coming out of dark the plants just spring up almost immediately. I’m really excited to see this work in the flower phase.
I bought a pair of these to replace a pair of Advance Platinum 900's and 2 Viparspectra PAR700's most of the time. And using my light rails they have not only replaced all those but my first yield was 30% higher than its ever been and I even used the old ones for all of veg. I've only had them for 8 weeks but took a chance and swapped them out while in first weeks of flower and glad I did even against good advice. I've made my money back and did it in a couple months. I'm sure you will too. I've had great success with this pair and can't believe how far we've come with LED's in such a short time frame but my electric meter is finally getting a long deserved rest. No A/C was used and CO2 could be used better with less exhaust need. My Platinum 900's had 10 fans between the 2 of them alone. Buy them and smile all the way to the bank. I'm getting more now for my other room. Those Samsung Diodes are the shignizzel. 2 thumbs up guys!!!
First time using this product and it works great thank you
Ive been wanting one of these for a minute for a couple reason's. First,footprint of trash.Those scrubbers,once shot,what do you do with that big ol dusty can filled with charcoal?. Second,with cans,you hang or stand.The charcoal, will always settlle in one spot or another,leaving gap that straight unscrubbed air can go out. The AirBox,uses packed porous AVcharcoal,that will not settle in the filters anyway they sit.100% of the air intake,goes through charcoal filter' twice.Alls you do is replace the filters,they are a little bigger than ones used with some home airfilters.But not as close to how the airbox filters work,or are constructed.Best Scrubbers out, imo.Will be doing an Unboxing Video,before i install. .
The computer aspect of this devise is really unnecessary. The press is not big enough IMO, as I can barely make it too 800lbs without straining myself. I'm 6' 170lbs and it takes all my strength to press 800lbs. I recommend getting one with a compressor. Computer unnecessary.
This little machine works great but because of the design the 2 air hoses keep the lid from sitting flat ,that causes 2 things so far ,some baskets touch the water some dont ,they all need to be level ,also feels like this lid is gonna warp a little
I got 2 of the hlg 320XL V2 Rspec for a 4x4, and couldn't be more pleased. They are well worth the money because they do as they claim! Flower density blows HPS/MH away, nevermind the vast reduction in heat. I keep mine 18-24 away and the plants love them. I would purchase from led grow lights depot again as customer service is impeccable. Thank you so much for these great lights, Erik, I might be replacing my veg pretty soon:)
Great service and speedy delivery
The 550 Light itself is a fantastic grow light with dimmable adjustment
Produces lush full flowers
Really should have dimmer switches or offered so it would be more plug and play out of the box.
Picked up 2 lights ,Very bright! Assembly was easy after watching video. Can’t go wrong with HLG products & great service - Thanks Erik ( Led grow )
Has done a great job in 4x4 for flower, don't get them to close.
Shipping was great, LED panel works great BUT MarsHydro shouldn't have cut so many corners while trying to compete with Horticulture Lighting Group. The driver is sub par (dimmer you have to fish for it with a screwdriver).
But, for the price the LED does what it was intended to do. Even stays semi cool to the touch now that I have a server rack fan continuously blowing on it!
The optic 8 is a beast, I got 2 in my 4x8 tent & my plants love it. It doesn’t create much heat in the tent, it’s very quite, & the bloom enhancers are the perfect touch. You really can’t go wrong with this light, especially considering the lifetime warranty it now comes with.
Great service and great lights. I like the adjustable dimmer.
This light is phenomenal. Im using it in a tent in an outdoor non heated location and with the light on full power with the cold nights of 55 degrees it puts off the perfect amount of heat to keep a warm 75. The spectrum is perfect. Par levels and energy usage are top notch. Can't wait for the v3 models
Great quality all around. I got this to be a space to root my cuttings and veg my next crop. Works great for me since it allows me to keep my cycle going. The ability to extend the height is also great just Incase you need a little extra headroom.
