I’m not sure why mars still sells those lights. The day of the blurple LEDs is over. Their TS, TSW, and SP series are hands down their best performing lights they sell. The lensed LED lights are no good @gallchin76. You want to stay away from LEDs that have their ballast built inside with fans. Check out the series I mentioned above and you’ll see they are a better buy.

I only use one as I am still waiting for things to become more normal so I can get a machine shop to punch my heat sinks and aluminum rails so I can assemble…

I won’t lie, I use them myself still too. They work great for Veg. Definitely not for flower.
