Roleadro Plant Grow Light, 600W LED Grow Light Full Spectrum Plant Light Dual-Chip Growing Lamp with ON/Off Switch,Daisy Chain for Hydroponic Indoor Plants Veg and Flower (only 110V)

So far, I'm pleased. The light arrived well packaged and in good shape. After unpacking the light, I was impressed with how it felt significantly less heavy than the older 300W LED light. That is good because it reduces the overall load on the rails across the top of my tent. Upon getting it hung in place of the old light and turning it on, I was again impressed. This time with the obvious increase in brightness. It is also significantly more red than the older light. All the LEDs are lit, and the heat exhaust fans are all running smoothly.I've been running it a few days now, and my opinion to this point is that it is a good LED light, and will probably be better than my old light. This light runs cooler than the older LED, also. I've got it hung over two tomato seedlings, and one autoflower seedling in a 36"x36"x76" tent. All plants look nice, have been growing nicely under the new light, and seem to like it just fine. I'll follow up in a few weeks with a progress report.--------------Update#1 .. So far so good. I only have the auto under it now. The tomatoes, which were were lower, and farther away from the light than the auto, were stretching a lot, and foliage growth wasn't good. So took the tomatoes and put them under their own light in the garage. They are doing much better now. The tomatoes were about six inches lower than the autoflower (due to the pots they were in), and not getting enough light. It seems that the best positioning of this light is 12 to 18 inches above the plants, and the plant that is directly under the light will do best.--------------Update#2 .. Not sure what to say at the end of this test grow. I grew a autoflower from spout to harvest. The plant grew ok. However, stretching was a problem, no matter how close the light was to the plant. I also added a 25W UvB t-8 during flower. The plant turned out tall, spindly, but covered with resinous flowers. While tricomes were numerous, fat, and sticky, the buds had no weight at all. I think it's genetics of the plant, and not the light. Unfortunately, I have not grown this strain before. Could be genetics and not the light. This plant was chopped and used to make some amazing bubble hash.--------------Synopsis .. This was a completely nonscientific test. Having said that, I think it's a good, inexpensive grow light. It is a well made, solid light fixture with bright LEDs that all functioned and all remained lit. The fans on the light are pretty noisy, but not terrible. Power consumption, and heat dissipation were considerably reduced, as compared to 400W HIDs and t-8 florescent lights. I'll take their word on spectrum. Due to there being less heat in the tent, I was able to use a smaller blower/fan for air intake and exhaust. This also helped reduce power consumption and noise. I've found that the plants will stretch under any LED grow light, unless they are close to the plant. Stretching seemed excessive with this plant, though. I also added a UvB light during flower, but that's my routine no mater what kind of light I use...As an inexpensive grow light for the hobbyist, who needs to keep costs for power down, I can recommend this light.

As a long-term devotee of LED lighting, I am extremely happy with the Galaxyhydro 300wlight. No, it is not top-of-the-line compared to some other lights I own but is very well-made,seems pretty sturdy and is very impressive forwhat it is.There is no doubt that this light grows plants.So little heat it makes growing plants in tents and small spaces a breeze.At the price point for this unit is undoubtedly a great value. Whether it matchesmy other lights in terms of flowering plants remains to be seen in tests.However I would heartily recommend it to all those who labor under limited budgets.And I can say without reservation that plantslove it for the vegative growth phase.Overall an extremely good value and was dispatched fast with rapid arrival in perfect order.Well-recommended!An update: After running my Galaxyhydro lights for several weeks now, I can say with assurance that these leds, ( both 600 watt and 300 watt), are equal to or exceed the specs. of my four-times-as -expensive US leds light units.The seller had my lights delivered within three days of placing my order and were attentive & followed-up with inquiries afterwards to make sure all was well on my end. Excellent service.As a professional grower I endorse the Galaxy hydro led grow lights without reservation.I've also purchased a 1200watt COB grow light for my next expansion. Can't wait to review this unit in the near future.In simply practical terms, the Galaxyhydro line meets the grow challenges of today at a reasonable cost. The classic "no-brainer" of all the choices I must make on a daily basis.And for those wondering if these work for the flower phase of their plants I say; " go for it".These lights are gems.UPDATE AFTER ONE YEAR IN SERVICE.It has been 5 complete cycles using 10 300 watt lights.Results have been consistently excellent.2 or even 3 units work wonders in 3x3 for flower.1 unit is more than sufficient for vegative in 3x3.Not 1 of.my 10 units have failed in the past year todate.I handle all my equipment carefully and never in haste,so if these units are destined for rough use or thrown around, you could break them.But the Galaxyhydro 300's are simply amazing for the price. I use a few 300's alongside larger much more costly units and almost hate to admit the difference between plants under the different "big"brands and my little Galaxyhydro lights is 5% at most.And I've been doing this work for decades. It's impressive.When I bought my first 6 last year I felt like a chumpat first, not believing the 300's could really compete with the double/triple cost "11" & "12" spectrum lights already in use in the gardens. Was I relieved when my fears were proved baseless..In any event, these lights are a great product, priced really fairly for both the budget conscience & the astute professional.A workhorse in my gardens.

I just got my light setup in my grow tent where I have a variety of vegetable seedlings growing. The light itself seems great so far and I will update this if anything changes. It's very bright and puts down plenty of light. The cable clips are extremely solid and I like the switch to be able to turn this off without affecting my timer. Two things surprised me the most though and the first one is the fan noise. I didn't expect this to be quiet but I was hoping it would be a bit quieter than it is. I have my grow tent setup in my living room right now - it will move to the basement before long probably sooner now because of the noise. Anyway, the fans spin very loudly/fast. It would be nice if there were a speed control for the fans as I'm pretty sure they don't need to spin this fast for cooling of these LEDs. The second thing I noticed was that the switch didn't affect the plug that you can use to daisy chain multiple units together. This seems like a pretty big design flaw. I love the fact that I can turn off the light with the switch because I hate having to unplug it from the timer or unplug my timer just to do some lights off work in the tent. It would make sense to me to have it control the plug as well, at least in my case. I can see a use case where you wouldn't want it to control all the rest of the lights daisy chained up but for me and what I'm doing this really would be a nice feature to have.I'd really give this thing 4.5 stars because everything else about it seems really good. I will update this in a few weeks to let everyone know how my plants are growing.
