Sun White Pro Spectrum

The Sun White Pro Spectrum is a commercial grade plant production spectrum formulated with higher blue light content and dedicated 660 nm (red) light in balance to promote strong root development, tight internodal spacing, higher rates of phytochemical production and increased flavonoid content. 

Easy Lamp Installation

Insert each lamp with the end cap marked L N into the lamp holders located on the same side as the fixture's switches and power cable. Once the lamp is inserted, rotate a quarter turn until the lamp is locked in place.

Sturdy Hanging Hooks

Removable metal hanging hooks allow for a quick installation using standard hydroponic hangers, zip ties, S-hooks and more (hanging equipment sold separately).

Dual On-Off Switches

Water-resistant dual on-off switches allow growers to run all 4 lamps, 2 inner lamps or 2 outer lamps to meet target lighting requirements for different plant types and growth stages.

Daisy Chain Cable Installation

Easily connect multiple fixtures by plugging the 6' power cord into the socket side of the next fixture for a versatile and clean installation.

Great product and results with my orchids

I've been switching over to LED units as my t5 fluorescent fixtures die. I'm glad I found Active-Grow- their products are obviously high quality and I have seen great results with my orchid collection that spends the winter indoors under lights.

Active Grow lights have been a great all around light. They produce beautiful reds in your lettuce, strawberries and beets. Don't waste your time on long drawn out searches for grow lights on YouTube these 'absolutely' will work for you.

Nice output

At 4 feet long and about a foot wide it feels pretty big, but is still pretty light weight. Puts out a good amount of light, the only dimming option is to only run 2 bulbs instead of all 4 though. The bulbs don't come installed and they are directional with no good guide to show which way they go, but reversing them doesn't damage them so you just flip them if they don't turn on.

Nice high quality light

I got this to replace some of my 2 bar lights in my grow room and I'm really happy with the light output and how light weight it is. Setup is a breeze and it's nice to simply have one fixture per shelf versus the two I usually have. It also saves on plugin space.

Successful retrofit

I had been looking around for a LED solution that would fit inside the adjustable fluorescent fixtures on my 4-level FloraLight unit which is at least 20 years old. After removing the old ballasts, wiring, and switches, then drilling some holes, the Active Grow 48" lights can be attached. I used eight 1/4" bolts with washers, but a dozen beefy sheet metal screws would probably work too. The result is lighter units that are easier to adjust up and down, more light, better light, less heat and no need to replace and recycle used fluorescent tubes. The only down sides are that the switches aren't quite as accessible, and the daisy chain outlet is blocked -- both minor matters which could be alleviated.

I bought the older 1.0 version so I am not familiar with the new housing changes for the 2.0 version. But I really like the 1.0 version I have now.

Plants LOVE THIS LAMP. My veggie seedlings' growth exploded under this fixture. It puts out a lot of light. I initially had 2/4 of the bulbs inserted incorrectly- and thought it was defective- but the seller quickly helped me troubleshoot the issue.

Well made and excellent for vegetable seedlings. I use a plant light mostly to grow vegetable seedlings to plant in my garden. With previous lights, my seedlings tended to be tall and spindly. This year I bought the 4 lamp fixture with the sun white spectrum. It is far brighter than my previous lights. Seedlings of tomatoes, peppers, and other vegetables were by far the best I've ever grown--fast-growing, compact plants with strong stems and excellent leaf color. The fixture is very solidly constructed and was easy to hang with a chain to adjust the height.
