LED fixture ?

[Billm302]

I am liking to replace some of my 4 foot Fluorescent fixtures with LEDs. My primary reason is heat. I built several 48”x 18” racks six feet high for my seed starting, so I need to replace the fluorescent fixtures with something similar.

What I am looking for specifically is a LED fixture whose coverage is an area of approximately 18”x 48” and something like 10,000 lumens. These hang about 4-6” above the seedlings so The 10,000 lumens is the area I need.

Most of the LED fixtures seem to be much more powerful and are designed to hang much higher than 4-6”. I do not have the airspace to hang the fixtures much higher than I already do. What type of fixtures am I looking for?

I have had good success with these using 2x per 48" rack in multiple tiers. Easy to adjust height but the transformer gets quite warm. No problems after one season of use when on 14 hours per day, 7 days a week.

walmart has the replacement led grow light bulbs that go into the old t8 fixtures.

Thank for the info. I am a little concerned that the light you posted a link for says the recommended height is 11 to 23 inches. I am looking for something that can be hung more like 4-8” above the seedlings, just like fluorescent fixtures. I don’t have the vertical space for 11-23”.

Billim: I have mine set up so that initially the fixtures are ~2" - 3" above the seedlings and progressively raise the fixture as the seedlings grow keeping it 4" - 5" above the plants when they are 4" tall as I prune them back. Hope this helps. BTW, the fixtures/LEDs are not hot so no chance of burning the plants. I use them for all of my seedlings (peppers, tomatoes, okra, squash, cukes, etc.)
