DIY light bar for 20g tall

I have a 20 gallon tall tank I'm slowly turning into a planted tank. I currently have a rather old school florescent light bar with a 15 watt bulb. The guy who sold me the bulb said I could grow some plants, and that was before I decided to play with aquascaping. I now know that the light is nowhere near what I need and I really don't want to spend $200 on a light bar. Is there any advice on how to DIY a light bar? I prefer LED, but anything under $100 is preferable. Heck if I can do it under $50 that would be great.

I converted a fluorescent bar to high watt LEDS. Very bright and inexpensive.

Wow, looks kind of complicated. Was it easy? How much did you spend on it and how long did it take you? I'm not an electrician and honestly don't know much about the computer aspect of some of this stuff. I'm more of a mechanical carpentery kind of guy.

There are a lot of good lights available for way less than $200! You can get a 24" Beamswork EA FSPEC LED off of Amazon for $28. There are a lot of other good options available. A lot depends on what kind of plants you're trying to grow and how you have the rest of your tank set up.

I'm reluctant with the Beamswork, I've read a lot of bad reviews, and read enough to hear that they don't do well with plants. I'm kind of interested in the Finnex Stingray, which is only a little more expensive, but has better reviews. I'm growing water sprite, amazon sword, 4 leaf clover, jungle val, dwarf hair grass, and java moss. I want the dwarf hair grass to carpet.

If you buy a Beamswork with the DA or DHL designation in the name, they will grow plants well. I don't know what reviews you are reading, but I'd guess that they are for the fish only lights.

couple options.

1 no DIY and get a 24in DA or DHL beamswork and call it a day.

2 DIY but easy. gut the 24in fluorescent fixture you have now. then put in 2-4 waterproof rigid led strips off [Ebay Link Removed] look up "Dual Row 5630 1m 0.5m Led Strips Rigid Bar Al Case Shell Clear Milk Cap 12V #4" on there I've used these before and will be using similar ones in my fish room. I have 2 currently in a 30" hood as a quick led light for a 29 gallon. works great. 2 of the ones I mentioned about are about 22watts which is more than sufficient for lowtech in a 20H

read around on here. very few bad reviews on the right beamswork lights. pay attention to the ones people recommend. DA/DHL lights both 6500k and fspec are solid choices for low tech tech tanks that are not extremely big (75 gallon or less) the EVO 6500k work great for high tech and bigger tanks. all work great with a TC420 if you want features like diming, sunset/sunrise...etc. really really great bang for buck. might not last forever.(my oldest one has been beat to piss and is 3 years old) but there 1/3 of the price of a comparable finnex and honestly I hear just as many horror storries about them dieing early.

I will keep your suggestions in mind. What I was looking at were not DA or DHL I don't think. They did say FSPEC though and had glue red and green lights.

I have this one in 36" on a 92 corner tank (24" deep and lots of area to cover) and I grow plants well.

And note that it is much cheaper on eBay (from the same seller).

Nice. I am looking for a second shorter light. It's not easy to cover a 1/4 cylinder with a rectangle.


Edit: I just took a look at eBay and the prices all seemed to be comparable to Amazon.
