Looking for ideas that has worked for anyone lighting a refugium with a cheap light.

I plan on moving my Kessil H160 back below my tank and will need one for my garage setup. Not looking to spend what it costs for a Kessil.
Money isn’t a problem here, just wondering what’s cheaper.
I see some 1,000watt grow lights on Amazon for literally $60....?

There’s even a $30 150Watt waterproof light too.... this stuff just keeps getting cheaper!

Let’s see your setups and ideas!
Probably looking at the 1,000Watt for $60 just because of the price. It’s completely overkill but dirt cheap.

Feit grow bulbs from Home Depot. I used a 9 watt for chaeto in small sump. I also have been using the 16 watt bulb for a desk plant.

There are plenty of other affordable spot lamps like that on Amazon.

Nicrew hyper reefs should work well. Broad blue spectrum is nice.

just put in a cheap 45 watt LED grow light panel. it was like 20 bucks off of amazon. came from china. If it doesn't work well I can replace with no pain. Its been in for a total of 1 day so i can't judge its success but the wavelengths are the same as the expensive kessel algae grow light.
