Review: SH2000 is one of the Best lights under $150 - This light is absolutely amazing. Amazing PAR readings and the specs the manufacturer gives are accurate. You just can't get UV, IR and dimmer at this price range, well built runs pretty cool and my plants LOVE IT! This may be a brand that is relatively unknown but it outperforms the Mars Hydro TS1000 I used. This won't cover a 4x4, but it's an excellent beginner light if you want to grow 1 large plant in a 3x3 space. Three of these can cover a 4x4 nicely to fill a tent that size to the brim. Get this light you won't regret it! Edit: After a little tinkering and more experience with this light I just love it even more. My 3x3 is actually 32" by 32" so 2.5 ft. by 2.5 aprox. This is the maximum 1 light will cover very nicely with flowering PAR levels from corner to corner at around 18 inches. The current moment the plants love it so much and the growth is so monstrous that I'm having to constant dim down to not burn the plants. This is an amazing light that I've found its so good point that I rarely turn it to 100% full brightness.
Review: Best light for the price SUPER BRIGHT - This light has changed the game! With the added supplemental UV strip my grow has never been better (pay no mind to the nute burn, seedlings went from organic soil to ocean forest at first transplant). This light is incredibly bright, in the photos its only 1 sh2000 at 50%, little to no heat, 0 Noise. I don't remember ever having plants at this stage in their 3rd week after breaking out of the seed. I've done no training, no fim, and no topping, yet I already had a BOOM I'm secondary top growths on ALL on my plants, 4 different genetics. I've made a time lapse that covers a 4 day period and the increased growth rate is insane. Also have to note that Sayhon customer service is A++ in a world where every company severely lacks customer care. They have responded and answered every single concern of mine and the free gift was incredible! They even upgraded my free gift! I will be sticking with these lights for all of my grow needs from here on out. Thank you Sayhon, these lights SMASH through this luscious canopy!

### ⭐⭐⭐⭐⭐ Awesome horticultural light.
*by S***. on April 29, 2021*

I have a 4x4 tent in early bloom. I have 4 lights set up for 6 plants. On one side is a Viparspectra xs1500 and a Mars Hydro ts 1000 I left these lights in place and removed the 2 across from them and installed this light in their place. Holy crap.....after 24 hours the 3 plants under the Viparspectra and the Mars were bending toward this light, I couldn't believe it. I use a par meter on my phone to adjust the lights to the same par so everything is equal and with all things equal the plants are bending to reach this light. I have a lot invested in the Vipar and Mars but will be replacing those lights with another one of these. I was blown away by how nice this light is. Not many lights in this price range have U.V. and hit the spectrum this light hits. I did a ton of research and this light is truly a horticultural designed light. It is NOT just a board with diods. This light has some serious mass to it and appears to be extremely well built. One nice feature is an off switch on the cord. The dimmer on mine goes from 50% to 100%. It came very well packaged with hangers, one ratchet yo yo and a very nice, well laid out manual. I attached 2 pictures that were taken in my empty dry tent showing the quantum board at 100% and then the Quantum board with the added UV light bar on (the picture with the purple/blue light), both at 100%. The other 2 pictures show total ppfd. The 1st is 1251 taken at 12 inches with just the quantum board lights, the second is at 1954 with the quantum board and the UV on. This light will produce some very serious, dense, big nugs. This manufacturer is a new, very serious contender in the horticultural lighting industry. A lot of attention to detail and spectrum went into the design.....I'm impressed. I will update my review through bloom.
