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.

Using the light to grow plant starts. The starts were already up and growing by the time I bought the light. Haven't noticed any fast growth but that could be because I don't have heat under the seedlings and the house isn't overly warm. All appear to be healthy with thick stems.

Used this light for starting garden plants (edible and flowers) indoors. Works amazingly well - my tomatoes have never grown so fast and my peppers have never looked this healthy. Almost too well - the tomatoes outgrew the space very fast! Definitely recommend and intend to get more for next year.

The only complaint I have is with the hanging mechanism - the hanging hook is about 6 inches off the top of the light, meaning for those of us growing on shelves, you have 6 inches of dead space between the light and shelf above from which the light hangs. I managed to rig up something using carabiners on either side to force the light higher, but would be nice if the hanging mechanism were on the light itself as with the old school shop lights.

Really happy with the light and hopefully it will last me along time. Will be starting my seedlings here in another month. Thank you for the great light ðŸ�

Grow vegetables indoors all year from seed to harvest using Active Grow sunlamps. I started out with the Active Grow SunWhite 8 lamp T5 fixture. My tomatoes, peppers, and cucumbers did so well that I decided to convert all my T8 fluorescent fixtures into ballast free to use T8 Active Grow SunWhite bulbs too (T8 review starts at 2:23). I have harvested so many awesome tasting vegetables. My lettuces did phenomenal under these grow lights. The hardiness and texture were way better than when I was using full spectrum fluorescent. Check out my YouTube videos at Amelia's Indoor Garden. To top it off they are located here in the US with excellent customer service. They truly have a passion for their product.
