Good grow light for orchids needing medium to low light. Versatile wavelength on-off feature
I bought the 2 foot led grow light to replace two 3 foot white fluorescent bulbs for growing small orchids. Length was an issue as I only have 3 feet of under counter space. The unit meets my immediate needs and seems at least as bright as the fluorescent tubes it replaced while using less energy. Screwed in with provided hardware, most of the unit is hidden with about one inch of stainless steel showing beneath the cabinets. I would have liked the linkage feature to be a little more flexible and so will probably not be buying additional units. Linking can only be accomplished 2 ways: either end-to-end for a 4 foot long size or side-by-side. I had hoped I would be able to link them offset by a few inches but still side-by-side. Alas, not possible with this model. I could not be sure until I had the unit in hand with the (minimal) directions to understand the configuration limitations. Otherwise, an excellent product. I have had at least three orchids bloom since I purchased the unit. I like the ability to turn off any of the 3 light wavelengths, (white, red, blue) because the pinkish cast can be temporarily turned off if you want to use the unit as a counter light during cooking prep, or if you have guests who may wonder about the pink light.

2 foot grow light
The 2 foot grow light is great. Very easy to use. It can be flush mount or suspended. We did suspended. Glad we did. After 5 days using it, we started to see the seeds start to break thru the dirt. We have it hanging about 18 inches from the top of the pot. We can move it up as the plants start to grow, You can also switch colors red white and blue or you can mix the different color lights as you need. Would recommend for the indoor gardener

A Perfect Grow Light With So Many Options!
I have nine succulents, each a different type, and each are very special to me. Succulents require plenty of sunlight, but New Jersey just doesn't have that! So to keep my "babies" alive and thriving throughout the year, I need to use an indoor grow light. I love the GRWL 24IN 40K 80CRI SLV M4 2 ft. 29-Watt Silver Integrated LED Grow Light from Lithonia Lighting. This light is made of high quality and durable materials. It's the perfect size for my nine succulents, but if you needed more, you can link up to ten lights either side by side or end to end. You also have options when it comes to the way you mount the light. You can either surface mount or suspension mount. Everything you need to do both is included in the box! The light itself has multiple options as well. There is blue LED, red LED, and white (full spectrum) LED. Each color light has it's own purpose and effect on your plants, and you can customize it specifically for the growth stage or needs of your plants. Each color has it's own toggle switch and there is an on/off rocker switch that shuts off all lights at once. There is a 5ft power cord which is perfect for suspension mounting. The grow light is very easy to assemble and the included instructions are very easy to follow. All of my succulents are thriving and have beautiful color ever since I started using this light!

Works Great!
I currently have three plants sitting under this, and all of them are growing well. They sprouted faster than the same seeds I have planted in an aeropod. The light was easy to set up. There are switches for each color so you don't have to cycle through modes to get what you want, as well as a switch to turn it off. All in all, it's a great little grow light so far. I do wish it had an auto timer feature though. I sometimes forget to turn it on/off. I guess I could get one that it plugs into, but that adds to the overall expense

Easy to Use!
I have had the Lithonia grow light for a few weeks now and it a great product. It was mostly ready for use straight out of the box. I only had to install the hooks and chains to hang the light. You can choose to hang the light or hard wire, but I chose not to hard wire so I can move it around as needed. You can also link multiple lights together, which I might do in the future, but I only have one right now. Once the chains were attached, I set them to the height I needed and simply plugged it in.
My plants seem to love the light. I am starting vegetable plants from seed, so I am using both the red and blue lights. That is the best and most unique feature; that It is very easy to switch between the desired colors and you can use multiple colors at the same time. My plants are in different stages. I have some seeds I just started so I am using the red light for germination, root growth and flowering. I also have some larger more developed plants which I am using the blue light for, to promote more vegetative growth. I planted green beans and it was only a few days before the seeds, sprouted and grew several inches.
I really like the option of the suspension mounting with the chain. As my plants grow I can raise the light higher to encourage growth and when are start new seeds, I can keep the height lower to keep them from getting too leggy. When all of my plants are ready to go outside, I plan on either using the white light as a task light or starting some indoor only plants. This product is very useful and I would definitely recommend. Grwl

Perfect for Ivy
I’ve always wanted to grow my own ivy inside the house, which I have been unsuccessful in attempting to use a natural light source. Using this grow light my ivy budded quickly and is growing like a weed. It’s the perfect light source and size. I can’t wait to try other flowers and plants!!!

LED Grow Light
The GRWL 24IN 40K 80CRI SLV M4 2 ft. 29-Watt Silver Integrated LED Grow Light is fabulous. Was easy to install and easy to use. Watching seedlings grow under it is so much fun. Love the long power cord and chain set. The different color temperature settings are very useful as well. Turns even a novice into a pro.

Happy Little Plants!
I'm so pleased with my new grow light from Lithonia Lighting. Very easy to hang and adjust height with the chains they provided. My tomato seeds really took off with this light as their sun. Can't wait to plant these guys and then start a new batch of seeds.

Good Light
I hooked up this light as soon as it arrived. In two days my plants showed a marked improvement. Leaves turned a dark green. Will use this light from seed to harvest. And will update review.

Versatile grow light
My flowering house plants, kalanchoe, orchids and cyclamens, are loving the red light. I have it standing next to the plant rack, but you can also hang this or hard wire it. The color changes include Red Light at 655-670 NM wavelength which is good for seedling starters or flowers. Blue light for plant growth. Red promotes flowering, so helpful for orchids, violets etc. LEDs do not lose strength as the old fluorescent lights did.

Like the flexibility to choose Light Color Combination
I have two of these lights and I use them for growing African violets. I like being able to choose the led color. I am using the blue-white for starters and will add the reds when it is time for them to bloom. They are doing well. I also like being able to use blue-white only when I am in the room so I don't have to look at red light. I have them on a timer and they go on an off with no problem. They are not hot. I just wish they were a little cheaper.
