SolarSystem 275W LED Grow Light Spec Sheet

The California Lightworks SolarSystem 275 is one of the latest and greatest additions to the indoor growing world. Whether you are a home grower looking for a single light, or a commercial grower looking to fill a facility of a hundred lights, this is one of the best LED lights currently on the market.

Why grow with the California Lightworks SolarSystem 275?

The California Lightworks SolarSystem 275 is a game-changer for the modern indoor grower looking for a perfect blend of power and efficiency. With an advanced, programmable spectrum that mimics the sun closer than any other light, the SolarSystem 275 can lead to healthier growth, lower energy consumption, and heavier yields.

California LightWorks produces high-power flowering lights for growers, by growers. These grow lights get results you can brag about both in terms of plant quality and yield. The California LightWorks SolarSystems 275 is one of the most reliable lighting solutions you can put in your grow room or grow tent. Here are just a few of the impressive features this light brings to the table.

High Efficiency, Low Maintenance

The California LightWorks SolarSystem 275 will produce the same yield as an HPS or MH light with an average of 40% less energy usage. Using the advanced spectrum control system will further increase efficiency and yield compared to old fashion fixed spectrum lighting. You can link the SolarSystem controller to a light sensor in a greenhouse to even further reduce wasted energy.

California Lightworks LEDs come plug and play and are super lightweight, so installation is streamlined. Add that to the advantage of never changing a bulb, and you have the industry’s most efficient lighting system.

Huge Yields With The California LightWorks SolarSystem 275

The California Lightworks SolarSystem 275 features top of the Line Osram LED's. These are driven to their maximum power rating using the exclusive active heat management system from California Lightworks. Higher power, higher yields.

Using the adjustable spectrum control to maximize blues and deep blues during the vegetative stage produces lush growth, shorter spacing between nodes, and less stretching. This increases the overall weight of your harvest, with huge, dense flowers. This is possible by maximizing red and deep reds in bloom.

Best Value Grow Light And Highest Return On Investment

The California LightWorks SolarSystem 275 features advanced design and manufacturing that produces a high powered LED fixture at a very reasonable cost. With a lower purchase cost, reduced energy usage and the elimination of replacement bulbs coupled with higher yields, this light offers the best return on investment in the industry.

Basic Spectrum Mixes for the SolarSystem 275

The following table are basic spectrum mixes for various growth stages for flowering plants. These spectrum mixes have been determined from 8 years of experience with the California Lightworks grower network, and are supported by various university studies on varying spectrum effects on Plant Morphology.

In general, blue light is essential in vegetative growth and produces lush growth and bushy plants. Red tends to make plants stretch in vegetative growth but is key for high yields in fruit or flowering plants. The SolarSystem 275 allows you to dial in exactly the spectrum mix needed for any phase of growth.

California Lightworks SolarSystem SS275 200 Watt Full Spectrum LED Grow Light Reviews

Great light
Really good lights. I bought one in '17 and another one this year to expand a little. Economical also. Both lights together use less power than a teenager.

close to harvest
I wasn't gonna give an evaluation until after I chopped but this little light has exceeded my expectations & is holding its own against my Johnson cx-6 that has a 140w. advantage my screen is full & expect to harvest around thanksgiving or shortly after but I'm gonna go out on a limb & say this little light is legit & fully deserves 5- stars

grow journal
forgot to add I'm doing a day-by-day grow journal of this light under the username "horribleherk " you can see it @ if anyone is interested

light &a tent
I bought this light & 2 of the 3x3 high rise tents so I already had a cob led & wanted a slightly smaller one as well I'm growing a single plant & a 24x24 in. scrog already having a few led grows under my belt have an idea. on what to expect & this is spot on the tent & light make a great combo & im happy with hydrobuilders service I'll be back with another review after harvest but right now everything is programming

sweet little light
perfect for my space, low heat and works great with the controller. Would get another if I expand.

under $400 is a steal for this light
I have run clw before with great success. I got the email about the sale on these, ordered and got the light in 2 days! I use this for my 3x3 flower tent now and have my older 110 in the 2x2 veg tent.

I think this manufacturer is definitely one of the tops in the industry right now. These new solar system lights run so cool and use low energy.

Thanks for the deal!

LOVE the new Solar System LED's
I loved my old 220w, unfortunately, I got rid of that to a friend and have never seen it again. However, it was a solid light and I liked it enough to get another. That's when I was recommended the new version, the 275. This light has a bit more power and is amazing in my 3x3. I have never had such perfect flowers at harvest. Low energy, low heat just like I remember, I'm a huge fan. Great for the average home grower and the cost is reasonable. This thing is well worth the money. get one and you'll see!
