I've grown both with and without uvb ,for indoor growing it is a absolutely a thc and terpene booster, Artificial sunlight lacks uv light .I have experimented extensively from short durations to longer even damaging leaves in the process for me I have found a timer with a 2 hrs on and 1 or 2 hr off intervals allows for the best results I go as many as 4 cycles per 12 hr lights on period, and most intensely from after the stretch until harvest.Uvb also helps control pest and mold so I use for short duration during early flower and even in veg to assure a clean environment.

Good

This has made life feel less scary. I can sanitize everything before it comes into the house. This includes boxes, my shoes and my purse. It is lightweight and very easy to use. I work with public and feel better knowing I’m not to contaminate the people I love.

The plants love the light. The unit doesn’t make much heat and being able to control the light color and intensity is great for the plants and the electric bill.

Very effective device for virus and bacteria. Excellent customer service

First off I was supposed to receive this tomorrow and I got it on Tuesday mid-morning. I set it up, basically plug and play and in 48 hours the plants are loving this light. It brought the temp of the tent up a few degrees but it's because of the better output and still in the range. You can tell it's a quality product once you get your hands on it. I can only grow 5 plants in my state and I can tell it's going to increase the yeild at harvest.

Very well built. Very good product. It's worth the money.

Great product , easy ordering and operating . Quality light output , also runs very efficiently and doesn’t run up your electric bill

TY!

great light! highly recommend!

i have to say, when i picked the box up, it was alot heavier than i anticipated which tells me its built well and not with cheap materials. After hanging my 1100 up and turning it on i was pretty damn surprised how bright this thing really was. Forgot my glasses when i initially turned it on and i was blind as shit lol I expected it to be a great light and so far im happy with my investment. I also purchased the controller and uvb add on and i have to say the controller is really cool. Eliminates bulky timers and has a bunch of different little things that you can tweak. Pending results i see myself buying more of them.

Be careful with it because I burnt my tomatos. You have to keep a safe distance. Working great with my peppers.

There is noticable plant health since switching to the Solo Xtreme 500. Haven't had it long
enough to compare electric savings but so far I am very satisfied.

I feel much better now that I can disinfect practically everything in my home now.

I'm currently vegging 2 plants in 4 gallon air pots and they look great! Compact internode spacing and lush green growth. Can't wait to see how this light does during flower!

Two SolarSystem 550 commercial series with UVB kits on a controller for my 4' x 8' tent. Can't wait till flower.
California lightworks the best company on the market. you want the best, this is where you buy. I have 6 lights from California lightworks wouldn't buy anything else...

Used for veg tent... small footprint

Very pleased

Awesome light!! I could see a difference in growth compared to my previous light within a week of use!

Hands down the best full spectrum light I have ever used my garden loved it even more and shipped super quick...top shelf quality

Super easy to use and quiet. Top quality for sure! A great purchase!

Pleased with the prompt response to fulfilling this order. Exactly as advertised.
Hoping it will serve as another tool to control virus and bacteria.

Outstanding, powerful, commercial grade, the UVC-15,
is perfect !

Very pleased with the light extremely bright with no heat keeping my 2 by 4 tent at a good temperature and my plants are just loving it

Solid well built units, plants have responded very well.
Nice having experts in our corner!

Free the Seed!

Seems to run well, keeps my 2x4 at perfect temps. Bright and good value

Absolutely love this light. You can control every spectrum for the best possible yield. I will be getting some more in the future!

These lights blow the old light out of the water (all the old lights) and you get to play around with the spectrum. I've been vegging some clones for about a month and the light gives you so much control. I'm having too much fun.

lights are working great

I tend to not like to write reviews before I have a good amount of time to play with the product. As I said in my first review I absolutely love the controler. I have watched the videos and wonder if there is a resource on spectrum changes to resemble the outdoor days? Now my New reveiw of your light. The light itself is much more impressive then I first thought. The light once I started dialing it in started to show very nice results. However I am still using another however your light is the main that one is in use! I will be getting more in the near future.

So far so good. I'm brand new to this and it's been working :)

Nice

My plants love it are dark green now,You Must get this light to make your plants Happy, thanks for best light ever.

Everything about this light seems to be of great quality. Worth every penny.

Perfect size for cleaning up our masks daily to get two or so days out of one mask

I love it going to be ordering another one in a couple of weeks.

Received early, in good shape, is working for me now.
May order another in the future, excellent light for the $

My first light was a SolarStorm750 in a 4x4. Loved the light but not enough umphm at the end. Decided to try ballast/bulb and heat was a major issue. Decided to pull the trigger on the SolarSystem 1100 with controller and couldn’t be happier. Temps stay much lower and the ladies almost double by the day. The controller is a must!! Solid build, custom settings and if any problems arise, customer service has you covered.

From the boxing, packaging, shipping to setup was a breeze. Easy to read instructions. Great investment with bigger returns.

Went from CMH LEC 315w lights to these LEDs and never looked back. Worthy of the investment.

I'd say this is extremely well made...not one of those plastic hand held type. This is a commercial grade that should hold up very well. Fairly light weight and easy to use one handed while scanning packages, etc. We're very pleased and would strongly recommend.

After 30+ yrs of using HID, I finally found an LED vender/product line that made me make the changeover. Research shows this to be a top tier company and my recent experience has proved that. The product is up and running, and my customer service interaction has been top notch. This is an American company I would recommend any day.

Just a better light! I have several others including three from Spyder farms and this is just superior. Wider spectrum and visible difference in growth and build quality.
