I’m an experienced grower. Over the years, for LED lighting, I’ve tried three other high end companies, for these other cases quality was good however results were okay/good. For the past recent years I’ve been using three different California Lightworks SOLARXTREME models. From my experience, the plant response to the SOLARXTREME models is incomparable. Plants sing and glow when lights are on. It’s really something special. I’ve always been super happy with the SOLARXTREME models however I’ve been a little bummed, for experimental purposes, this series is without built-in control for timing, spectrum adjustment and dimming. I recently purchased two SolarSystem models with the external controller. Wow! It’s exceeded expectations. Plants continue to glow and sing plus I have all the controls I need. No exaggeration here. I absolutely recommend the SolarSytem series and the controller and the SOLARXTREME series. One of the SOLARXTREME models I purchased had an electrically broken fan on its arrival. Customer service / tech support over the phone was perfect for handling the replacement. Also made in the USA. I’ll never buy from another company. Quality is top notch. The controller is well designed as well.

Started using this light in my 2nd tent mid veg (5 Pine Tar Kush & 2 Hindu Kush) and has took over great so far swapping out my dual led's I was running . It corner to corners better than anything I've come across . Getting new growth in hard to reach areas no dinking around adjusting pots . Its a little on the spendy $ side but with lighting you get what you pay for . I definitely recommend

I really love being able to have control of different light spectrums this is perfect for me to dial it right in! So easy to use and make your own unique schedules. I definitely recommend!!

This is a great grow light had it about 1Month so far it seems to be doing very well looking forward to the end results!

I love this light. The light is well built, stylish, quiet, and made here in America. The light is very bright and produces very low heat. I use the light for growing vegetables in a small space. So far the plants are loving this light. I would definitely buy this light again.

the light is well made does great job ,only complaint is U.V.B. cannot be on much when mounted to lit would have upgraded to 550 if I had known,but great lite

You know I haven't plugged in yet (I will soon) The delivery was great I was surprized at how quick it arrived , I just opened the box tonight , and it looks to be very well built , I'm excited to try it out Thank You,Sincerely Todd

Order was received in a timely fashion. It was easy to install the UVB lights and hang them. I haven't setup the controller yet.They are significantly brighter than my last lights. I'll review again after my grow is complete.

This light great liked it so much I bought a second one

I've just started using the light but it is definitely worth paying extra. Easy to use and it completely covers my 5×5 tent. Plants are growing like crazy

Working good but only couple weeks in.

So far it's an awesome light and the plants seem to enjoy it 😀

I started with 1 ss550, then I got a ss275 for my veg tent. I just got my second ss550, both have the uvb. These things are very well made, the controller is 10x better than any I've seen. My flower roo. is so freaking bright I'll never get to 100% on these lights. Tight smelly flowers. The uvb bumps up tricomb count and gets those things to ripen a bit faster than without. Top quality lights grow top quality flower, if that's what your into, you gotta piny up a little. And having the spectrum control and a few grows under your belt you can completely manage the height and node spacing.
