For about the same price you can get an actual LED grow light from amazon. I use some and they works great.
I run them on a timer for 8 hours when I'm not home.
I use another LED floodlight, just a little 10w one, for accent lighting. Its dim enough that it doesnt cause any algae growth or anything, and it looks like the moon shining in a little pond. I run that one for about 12 hours overnight after the grow lights turn off.

Grows my chaeto like crazy. I used a small piece of wood behind the tank to prop it up and angled it to give a full light. I also put it on a smart plug and set it to come on and turn off at the times I want. 100% recommend.
This cheapo Amazon grow light that grows chaeto like a champ.
They LOVE light. I bought this light to supplement my succulents and seedlings during the winter time and all my plants are thriving! I keep it about 4-6" above the succulents and they grow nice and full, without much stretching at all. I keep the soil moist when they are plantlets, and once they start making their own baby plants I let the soil dry out completely for a day or two before watering again.

This works great in my sump and it’s cheap.
I bought this light off amazon and applied with adhesive velcro like this. Works perfect
I did not put an intank in chamber 2. There's a ledge at the bottom of chamber 2 that I cut a sponge to fit over, then stuffed the Chaeto on top of it, then used this light velcroed to the outside. The light covers the chamber almost perfect. I have not scraped the honeycomb off.
