I'm trying out this new grow light for the upcoming season. Been using 4 ft. T8 4 light fixture for many years but thought I'd try LED's

Let us know how it works out. I've been looking at the "full spectrum" or "sunlike" type lights as a next thing to try.
Watch out for edema on tomato seedlings with LED lights. Some varieties are more susceptible than others, but basically tomatoes need some UV and IR wavelengths to do best. If there's some natural light too, that would cover it.

According to the spec sheet this light is supposed to have your above mentioned wavelengths. However the one I just received has absolutely NO wavelengths at all cause it doesn't work at all. Nothing, no way no how. So I'm returning it for a replacement. This does not inspire confidence in a product. I should get the replacement in a few days so we shall see. More will be revealed ! ;)

We have three hanging over an 8 foot table in the basement. Not sure any more the brand. Two were supposed to be the same. but we bought them at different times from Amazon and we like the first one better. The third was one that was linked to here as a special sale price. We will never go back to any other type of grow light. We have some cabbage and broccoli under them now doing great. My wife has grown leaf lettuce under them in the winter very successfully.

I've been using a 4 ft - 4 bulb LED Active Grow for 4 years now that I am completely happy with. It was purchased on Amazon.

We got a space-saving Harris Seeds 4 Tier/16 Tray unit a coupla years ago and couldn't be happier. The plastic cover creates an humid Equatorial environment that seedlings just LUV.

For taller seedlings, & sprawling cukes/zukes/squarsh overflow, we replaced our many other units with these from Home Depot. Liked them so much that we also replaced other basement shop lights with them.

Most of my seeds go under 4 tube T8's. I also use cheap screw in LED'S with the diffusers removed.100 watt, 5-6000K in daylight. Very bright white light. 15-20 consumable watts. Don't get too caught up in broad spectrum lighting. You're starting plants to transplant into somewhere outdoors. Bright white LED lighting works quite well. One drawback I've noticed is magnesium deficiencies. Easily correctable with a couple drops of cal-mag or Epsom salts.
Also commercial high bay lighting is very cheap and throws off big light. The picture shows a 174 watt Lithonia fixture that measures about 11" x 22". A friend works at an electrical supply house. This was a store return and the box was marked "flickers". Barely noticeable to my eyes and plants don't care. This light can cover a large area.

I'm going to attempt using grow lights for the first time in 20 years.

The technology sure has change. I picked up a WalMart Great Value 2 foot LED fixture, switchable between blue spectrum, red spectrum, or blue and red spectrum. For $30, it's worth a shot, and it was the last one in the store. Apparently several others are giving it a try, as WM is well stocked with all of their other grow light products.

I ordered a 4ft. shop light to experiment with. It was a single bulb fixture and I thought I wanted a double bulb LED sunlight. The single bulb now lights up the basement like never before and the double bulb LED bright white will be here Monday. The new light will be used on peppers this year with the 20 year old fluorescent fixtures remaining in use for tomatoes. If things work out I may begin switching out fixtures. It will still be shop lights not grow lights.

I went ahead and bought two of these on sale in the 3 foot size. On the packing it says for houseplants and leafy greens, but in the description it mentions full spectrum. The watts are low (20) though. I can't remember the watts on the 3 ft model.

Can I use these to start tomatoes, and at what point do I need to switch to a different light. I don't do houseplants, so anything recommendations besides lettuce to grow for transplant outdoors in early May?

The LEDs I'm using for greens are shoplights, not designed for plants (but "suitable for damp environments" and -20C to +40C). They are 4ft, 40 watt, and 'cool white' 4000K. They are fine for winter greens, although some differences have been noticed - plants grow taller under fluorescents. Under the LED, things like bok choy and napa cabbage will reach a certain height and then they just grow sturdier without getting taller, like they don't want to get any closer, vs the fluorescent fixture they will grow right up into it. Lettuce seems to like the LED and arugula did better under it than the fluorescent hung in a cold window.
These are the lights that gave my tomato seedlings a bad case of edema, when I let them get a little dry and then watered.
So they are not the same as LED lights designed for plants.

I am so happy I found this site and all the helpers abound here. I didn't know what grow lights to get for my new shed growing but decided on these because they seemed to be good enough and cheaper than what it would have cost me to replace the bulbs in my old light fixture. They seem to be doing pretty well, and I am sure I am needing more experience but things are growing so that is a plus. I found these listed in numerous places online, I bought mine in 2 packs from WM, but you can get them in many other places and there is lots of feedback on them at Amazon.

I use Costco's Feit 4' LED 4000 Lumen Shop lights and have been very happy with them.

These days these lights are smart lights controlled by your phone. They are dimmable and you can use warm, Cool or Daylight Color.
