Roleadro LED Grow Light 1500W Plant Light with 3500k Full Spectrum Growing Lamps for Indoor Plants Greenhouse Succulent Hydroponics Veg and Bloom Plant Grow Lights-1500W

I now have four of these lights. I use them in my homemade hydroponic setup. They provide all the light for my plants. I'm currently growing lettuce, bok choy, green peppers and serrano peppers, all of which do splendidly under these lights. I think that these the Best Buy for the money. They are cool and quiet, full spectrum and my lettuce grows like crazy. The peppers are producing wonderfully. I do not feel like you could go wrong with these lights at this price point or any other. Rarely am I 100% satisfied, but this is one of those times

A great light that is bright and You can't beat the price to performance. I had a lumigrow 650w light. It was much hire grade and cools way better but I can't afford the lumigrow. Maybe one-day high end lights will be cheap! The diodes in this light are cheap China ones, o well. I still love the light. I did originally give this light 4 stars because it said 600w what I’m wrong here, they give the real wats somewhere else which is around 150w. The 600 is just an Equivalency or something. Again this light is awesome I’ve Purchased 4. I convinced another friend of mine to purchase two. I am in agriculture and food science technician, so I know what I’m doing with grow lights and I’m telling you these are good!

So far this is amazing, no issues. We took our tropical plants inside for the winter. We have an "island" downstairs with this light above. They look healthy and happy so far. The hibiscus and mandevilla are still flowering.ENERGY.. Our electric bill has gone up about $8 since adding the lights. I expected that.Heat.. it has set off a detector but it's because it was placed to close to it I think. Overall it doesn't feel too hot to the touch.

SUMMARY==================================================I ordered 4 different grow lights in the 1200w-1500w "sun-like" class and ran a simple experiment collecting data on the light output, noise, weight, and temperature of each of them. The results can be found below along with a discussion so you can pick the one that best suits your needs. If you don't want to read the details, in short I found that the Oneo brand produced the best light output in terms of center and spread, with a similar energy usage compared to the others. Ygrow was the quietest by about 5 db from the top and 10 db from the bottom, but it was the hottest, adding 50°F (28°C) to the room I tested the lights in, 15°F more than the next one and 30°F hotter than the coolest one.Note: While the Lighttimetunnel and Roleadro lights were individually measured, it was clear the moment I opened them that they were in fact the same exact light rebranded under different names. Since their measurements came out to be the same as well, I have collapsed them under a single name "Multi-brand" in the data section. All the grow lights had very similar contents -- all had almost exactly the same carabiners and metal wires. They all had similar NEMA15 to IEC-320-C13 power cords. Two grow lights (ONEO and Ygrow) came with the (exact) same additional rope hanging device and thermometer/hygrometer that was almost the same (one had a wire with an external sensor -- so you can measure the temperature / humidity in an area other than exactly where the device is -- and one did not, and sadly I don't remember which one came with which!).Here are the lights I compared:Lightimetunnel 1500W LED Grow Lighthttps://smile.amazon.com/gp/product/B07RHQZVRD/Roleadro 1500W LED Grow Lighthttps://smile.amazon.com/gp/product/B07P3BXRDC/YGROW 1500W LED Grow Lighthttps://smile.amazon.com/gp/product/B07PWBZ9F7/ONEO 1200W LED Grow Lighthttps://smile.amazon.com/gp/product/B07RZL27YX/As a side note, I also have a Bozily 300W LED Grow Light (https://smile.amazon.com/gp/product/B07MLVRNFF/) which is in a different class (300W). While it produces far less light output, it's advantage is that it produces almost no noise, far less heat, and is much lighter than the others. Also, it has a built in timer so that you can have it automatically turn on and off each day for a certain length of time. If you aren't going for maximum light output (i.e. around the same output as the sun), I would recommend considering lights in this class instead.The figures (pictures/charts/etc.) mentioned in this review have been attached so you can view them directly here on Amazon.com, but in case Amazon's system makes the pictures difficult to view in detail, I have also uploaded them here: https://imgur.com/a/QAjfrzwMETHOD==================================================Using a series of poles and wire attachments, I hung each of the lights such that they were all 21.5" (54.6 cm) from the floor (a seemingly random number, but it's that height only because that was the height of the first light I put up and I put up remaining up to match that level, see fig. 1). I used a level to make sure all the lights were reasonably level (see fig. 2).I did the best to measure the features I think most people will find important. These include: light color, lux output, lux spread, noise level, energy usage, size, weight, and temperature. Each measurement was taken at least two times, so the resulting numbers you see in the data below are the averaged numbers.Light and Noise DataFor recording lux data I used a URCERI Light Meter, which measured the ambient lighting in the room at the time of measurement to be 23 lux. Lux data was recorded by using the MAX function on the light meter and finding the max reading I could get while moving the light around flat on the floor under the light (in all cases, the maximum reading came when the light meter was centered underneath the grow light). For lux spread, I moved the light meter 1ft (30.48 cm) away from the point of maximum brightness (nearly touching the white wooden board as shown in the pictures). For recording noise data I used a I used a BAFX Products Decibel meter. I took measurements in two places: directly on top of the grow light, with the microphone positioned in the center, and 6" below the grow light, also in the center. The ambient noise level in the room of the experiment was 45.6db.Energy Usage and Temperature DataAfter taking lux and sound measurements, I plugged each device into a Kill-a-watt energy meter and left each device on for exactly 3 hours before I measured the energy usage. I divided the values by 3 to get the per-hour usage. At the same time as measuring the energy usage, I also measured the temperature 5 times by pointing an infrared temperature gun at the underside of the grow light (i.e. directly at the LEDs themselves). The experiment room had what I would characterize as "reasonable airflow" (a door was open and a cool breeze from outside could be lightly felt), with an ambient temperature of 80°F (26.7°C) and 49% humidity.See fig. 3 for a picture of the measurement instruments.DATA==================================================See fig. 4 for a table of the data and some charts.DISCUSSION==================================================I won't belabor this already long review with a detailed discussion of every aspect of the data, but I will cover some of the important ones.LightAlthough all the lights were advertised as "full spectrum" and/or "sunlight" grow lights and had similar listed wattages, the color and intensity of the lights varied surprisingly significantly. I am not an expert photographer by any stretch and the colors are a bit off but I tried to capture these differences in figures 5-7. Figure 5 shows the photos of each of the lights from the same position with the same settings in an animation and Figure 6 shows the white-balance corrected photos in an animation. Figure 7 shows the same uncorrected photos from Figure 5 all stacked vertically in case you prefer a static image comparison over a gif animation. Note that Figure 6 though corrected is still not perfectly accurate in terms of color that I saw with my eyes (it appears they all produce perfectly white light from the photos, but in reality it's not the case). The whitest white was the Multi-brand light, with Oneo coming in close second (just the slightest tint of yellow). The Ygrow lights were noticeably yellow, but not necessarily in a bad way (and notably still not as yellow as the 300w Bozily lights which I do in fact think are too yellow for my taste).Although all the lights use similar amounts of energy, the Oneo light definitely produced a significant amount more light overall than the others. The Ygrow light produced about as much light directly beneath the unit as the Oneo light, however as you moved away from directly beneath the light the output dropped much more sharply than the Oneo light. Because the difference in monthly cost was only around $1 between the Oneo and the Ygrow, it seems like the Oneo is the best value when it comes to light output.All the lights provided definitely can reach outputs equal to and exceeding what the Sun produces. The Sun was measured at a peak of 92.5 klux at 3:40pm in the afternoon in San Jose, CA, and several subsequement measurements on different days gave similar values in the low 90s. All these lights will produce that much output as long as you place your plants quite close to it (around 8" from the light). As you get even closer, you can easily far exceed the Sun (I measured 175+ klux within a few inches).SoundAs the fans for the grow lights are all on the top, the sound is mostly directed upwards and therefore depending on how you use the lights you might weight the importance of the two sound measurements differently. It seems much of the sound is produced from the relatively loud fans, so one might consider replacing the fans with some quieter ones such as Noctua brand fans.TemperatureThese lights all generated at least an additional 20°F (11°C) and upwards of 50°F (28°C) in the room I tested them, so ventilation is certainly important when using them near areas where people will reside.

Great light for starting plants. I have a tomato and habanero under it. Lots of healthy foliage and is currently flowering.The tomato has started producing. Will post updates if I actually get to harvest.

Great grow light. I have the Roleadro 300 for 3 years with no problems so I bought the 600 in September 2020 and haven't had a problem with it. After only a month it seems to be going great no problems and I love the fact that can dasiey chain them

This light fixture was plenty bright but apparently not the correct wavelengths for my plants.

This light does a great job for a closet grow or 2x2 tent grow.
