A new shop light is only $40.
But most like a light that is about 6500K, 4 ft long, 4 tube bulbs or more, t5 or t8 wide bulbs.This will cost more, but I think it's worth it. Mine us so strong that my seedlings can't get closer than about 4 inches, because it puts out some heat too. I have to watch the water in the seedling mix carefully.I spent about $120 on it, but its a one time expense, might need new replacement bulbs in a few years, but those are cheap.
In my opinion, grow lights are NOT the place to economize.
And you do not need to micromanage every single seedling's growth, just keep the light closest to the tallest. Once you get that leggyness under control, and you see how much stronger they are from the getgo, you will never go back to the philosophy that leggy is OK because they get strong after transplant. You will see the permanent differencd a great start gives them.
