This 100W (actual, I confirmed) Grow Light from the SOMYMORE Store appears to be a very good lighting value at the current price of only $55.99; that's with a 30% savings coupon included. Especially since it has all the makings of a solid product. Here’s why… ✔︎ Excellent build quality and attention to detail. All metal exterior body, internal cooling fan, soft touch digital display…it’s a combination of features that really makes this grow light shine. No pun intended. ✔︎ The soft touch digital display is unlike any I’ve seen before. It’s very cool. Options include ON/OFF, lighting mode or growth stage (seeding, vegetative, and bloom), intensity/brightness (10-100%), and timer. The buttons respond to the lightest touch. ✔︎ The cooling fan does a great job keeping the fixture cool, and the sound is not as disturbing as some cooling fans I’ve heard. In fact, I wouldn’t have any problem placing this grow light in the kitchen or other gathering place. Although it’s best kept away from crowds. More for safety reasons. ✔︎ From the dimensions of the diodes, they appear to be of the 2835 series. Probably the most common LED found in consumer grow lights. And for good reason, they offer a good balance of output efficiency and cost. ✔︎ The grow light has a total LED count of n=256, laid out in a 16 x 16 array. The color distribution (my count) is as follows: n=106 (Warm White 3000K) n=106 (Cool White 5000K) n=4 (Blue 460nm) n=36 (Red 660nm) n=4 (IR 730nm) ✔︎ The light has n=3 different lighting modes. They are “SEEDLING”, “VEG”, and “BLOOM”. Not surprisingly, they are more similar than not, with the 3000K and 5000K white LEDs making up the bulk of the array. In fact, the only distinguishing LED feature is that Seedling has n=4 Blue and Bloom has n=4 IR. Although a count of 4 seems like a very small number, relatively speaking, it could be enough to contribute to the full-spectrum profile. I'm just not sure... ✔︎ Using a quantum PAR meter, I found that the peak PPFD from each of the 3 modes varies by less than 10% of MAX. For example, at a distance of 12-inches, SEEDLING was 595 umol/s/m2, VEG was 572 umol/s/m2, and BLOOM was 613 umol/s/m2. This should come as no surprise considering they only differ by a handful of LEDs. Still, of the 3 modes, BLOOM has the highest PPFD output, followed by SEEDLING, then VEG. This correlates with the power consumption (W). ✔︎ The listing provides PPFD maps at three different distances, 12, 14, and 18-inches. Peak values from the maps are shown below compared to peak PPFD measurements that I collected with the grow light in BLOOM mode. 12-inches Listing...1134 BLOOM...613 14-inches Listing….653 BLOOM...458 18-inches Listing….450 BLOOM...289 ✔︎ The illumination pattern of the grow light provides enough core PAR coverage for a 2' x 2' grow tent. Maybe even 4' x 4'. ✔︎ The timer feature works as expected. No surprises here. ✔︎ The grow light has some weight to it, checking in at just over 3lb on a scale. I have it suspended from a heavy-duty light stand, and it’s a good set-up. But the stand has to be heavy-duty to manage the weight. ✔︎ The listing advertises a 1-year warranty. Unfortunately, I did not see any mention of a warranty in the user manual. It might be worth checking with the seller to confirm. Overall, this is a solid grow light for under $60.00. The only observation that gave me pause is the relatively low number of “unique” LEDs that are intended to broaden the full-spectrum profile. On the other hand, I’m not an expert when it come to horticultural lighting, so it very well may be that a grow light only needs a handful of Blue or IR LEDs to make a difference. Regardless, the PPFD output is good, and the build quality is exceptional. As long as the electronics hold-up over the long term, this could be a fantastic value buy. Especially if the warranty holds up. I’m happy to recommend. Based largely on the build quality and the PPFD output. ⭐️⭐️⭐️⭐️⭐️
