2026 Upgraded SH2000 Led Grow Light,Dimmable Full Spectrum LED Growing Lights with UV&IR for Indoor Plants Increase Yield & Crop Quality, Plant Growing Lamps, for 4x4 Tent

Great grow light. Very well made. My plants love it.

I bought 2 of these lights on September 28th 2024 based on the excellent reviews, particularly as regarded the companies responsiveness to customers with product problems. they are quite powerful and both worked spectacularly well until one of them began to experience failure just under a year into use. the blue light strip began to sporadically flicker at full brightness, and then being the majority of the time barely illuminated. so not only must I keep the brightness lower than its full capacity, the supplemental strip is effectively defunct. furthermore, how am I to know how much longer it will maintain even this impaired integrity? as customers had before me, I emailed support @ sayhon.com; it took multiple attempts and a bad review because my message was directed to their spam, but upon gaining their attention the response was to offer a replacement light. the lights are really fantastic and I appreciate the stand-up customer service--most companies these days neither offer such excellent warranty nor stand behind their product when it does fail. just be persistent when contacting them in case your first attempt gets lost.

I definitely recommend purchasing this product! I was very impressed with how easy it was to put up, and it came with everything you need to do so. It’s a great light source and does what it needs to do perfectly!

It’s good light it is decent bright plant growth is decent showing small improvements then my 100w light good for value

Works great for winter months when there isn't enough sun, improve growth rate from barely usable back to normal summer like levels. The control knob is nice and solid, heatsink is nice and heavy. Definitely recommend using with a timer. Fits well for something around 2ft x 2ft. I will be installing a light hood of some sort as well.

At first, I didn't get it, but then someone from the Sayhon company explained to me how to use the IR\UV light. The supplemental IR/UR lights are to be used for the seedling stage (to promote healthy roots, and resistance to seedling diseases) and the flowering stage (for higher yields). Ultimately, everyone will have their own preference as to how to utilize the IR/UV lights and there really isn't any wrong way. I'd just like to say, that even without them, the main lights are more than efficient for my plants in my 2x4 tent, and they are all really thriving like crazy. I currently have the light at the highest setting of 100% as I am in mid vegetation, and the light feels more warm than hot (when I place my hand on top of the light to see the amount of heat that comes from it (and it's not hot at all), and they are definitely bright enough. I also like how the dimmer knob can actually turn the light off and on. With this grow light, my tent is at its best set up that I've had so far. I'd definitely recommend them. This Sayhon company is serious and really cares about customer satisfaction, too. The representative that I was in contact with realized that I was a bit frustrated by not understanding how to use the supplement lights and after thoroughly explaining it to me, he even sent me a major bonus item for my tent set up, at no charge. I am glad that I decided on this grow light. I'll definitely continue to look into this company's products because of it.

First I would like to say is, I have been growing tropical plants indoors for over 5 years and use a HLG Diablo which is the best grow light IMO. This light is 1/5 the price and as far as PAR reading, at 18" from canopy, this light holds it own. I am getting high 900s plus PAR at full strength towards the center in a 4x4 tent. You would need 2 of these lights to get close to equal coverage in a 4x4 if you wanted to grow cannabis. For tropical fruit trees, 1 of these lights is going to do the job. In 2x2 or even a 3x3 tent, one of these lights would be great for cannabis. If you're on the fence about buying this light, just do it....you won't be disappointed. Excellent light even if it was twice the money. I also have owned the smaller light (SH2000) for a few years for seedlings and it performs extremely well. The build quality is excellent, efficiency is right on par with more expensive lights, no pun intended.. Sayhon is the real deal! I am not affiliated nor did I receive anything or promises to alter this review, this is my honest review of a great product. I generally don't write reviews, but this company deserves to be recognized.

I am a cultivator\caregiver in the state of Missouri. I have purchased one of these lights and liked it so well that I purchased another. It has multiple light settings and dimmable switch. I don’t know that it last yet, but so far it is a great light. I have to update my review. I bought 2 of these lights from Amazon. One of them flickers on and off. Tried contacting the manufacturer with no response. Then they finally contacted me and said they would send another light. But, that was 2 weeks ago and haven’t received any other response from them or light. They finally sent a light and it was the wrong one. But, they did finally send me the correct light. So they have made good on sending me the proper light just took a long time. The customer support did make things right. They have done everything they can to help. That’s why I changed from a 1 star to a 3 star. Wanted to update my review. These lights for me haven’t lasted. I purchased 4 o lights. One went out really quick, one lasted a little over 4,000 hours, the 3rd about 4,500 hours. So, they don’t last near as long as they say. They did replace the one that went out really fast. I have another brand that has out lasted these by triple and still working. I wouldn’t recommend these. I’ve changing my rating to 1 star. All these lights stopped working. None lasted more than about 8,000 hours. In my opinion they’re are garbage. There is a picture of where they didn’t solder wires together

I had to take all my tropical fruit tree (citruses, papaya, passion fruit, cherimoya) under this lamp for them to survive the winter and they all look like they are living thier best life!
