The 5000 lumens of daylight 6500K light really makes a difference in plant growth. I’ve used them in a setup with dense foliage, and the light penetration was impressive.

Honestly, they’ve become my go-to choice for high-output T5HO lighting.

However, keep in mind that their high brightness might be overkill for small setups. Also, the 54W power draw is significant, so make sure your fixture can handle the load.
