For a 5x5 space I would go with individual COB lights - individual lights will give you freedom to place different color lights in different areas and you can add customize as you grow ..... also consider different plants have different light needs, with individual COB lights you adjust each to their own ....
One website that reviews other lights and sells their own is MIGRO https://www.migrolight.com/ .... Shane the owner is Flippin honest and gives excellent reviews, his knowledge base is for sure worth exploring....
Another manufacture with very high efficiency lights is Optic https://opticledgrowlights.com/ ..... Some knock because they are built in China which is true but so is the iPhone - but both products are engineered in the US
And finally, especially if wanting DYI HLG is very highly rated .... https://horticulturelightinggroup.com/
Three choices - good luck with your new lights!
Hard to make a choice with this stuff tbh. All expensive but I'm ready to spend the money. It's just that I don't want to regret my choice.
