    Good value compared to similar products. $8 is about as cheap as you can find with these T12 48” grow lights. I don’t like the printing on the bulb, and I found it difficult to determine the light color value; i.e. the packaging does not have much information printed on it other than 40W, 4 FT, T12. It helps to know the lumens and light color value. Other than that, only time will tell how well it works.

    Beautiful light from these lamps, very natural color rendering. Looks almost exactly like the light coming in through a nearby window. Very expensive for fluorescent tubes though, you wouldn’t want to light a warehouse with them. I use them for a plant display and the plants look great. They would probably work well for any feature display application.

    The color temperature appears higher than the quoted 3,500 K.

    I’m only giving them a “Fair” for value because of the cost, but that’s kind of in the eye of the beholder. I think if “value” is your primary concern then you should probably choose a different lamp of lower price and lower quality.

    I knocked a point off for design because these lamps aren’t available in an F32T8 format.

    I needed better lighting for plant growth in indoor hydroponic growbed to help remove nitrates from aquarium. The plants responded quickly to the lighting and helped to reduce the build up of toxins that were negatively affecting the fish in the aquarium.

    I have gone through ten of these lights in just over 8 months. They are said to last 9 years, and some 1900 hours, which just doesn’t ring true. They last maybe a month, or two, on for twelve hours a day. They commonly go black on the ends, then die. The store has been replacing them on store credit, but irt is still a hassle to take then down, return them, and re-install.

    This bulb is great for growing violets and for aquarium’s with live plants.

  6. Lowetta

    What can one say? You buy a grow light and it works, Nuff said 🙂

  7. Demetri

    We bought this bulb to replace a more traditional type fluorescent tube over our bed. This light is much more pleasing. It is full spectrum and has almost a mauve/violet tinge to it. My wife hates white fluorescent light. She actually likes using this bulb for reading before going to sleep.

  8. Azalea12

    Plant light bulbs work well keeping house plants alive by emitting the proper light spectrum needed by all plants to survive indoors. Replaced the same existing bulbs after 6 winter seasons. Very economical compared to similar plant light bulbs on the market. Great product at a great price!

  9. Barnes

    I was having issues with my seedlings becoming to stringy and long. I double fixture with these bulbs did the trick.

  10. Bruno

    They are so much brighter than the other brand. I have used them to grow plants and brighten the colours on my fish.

  11. tigert

    very nice price even beat out the other guys by about 50 cents

  12. Curtis

    Looking for the right piece of wood sometimes comes with a bit of creativity and adaptation, and in this case the ability to outguess the project as well as planning around the object of your design. Having the resources at your finger tips is helpful and so thanks LOWES for being there>
