I was highly recommended this light by the cactus and succulent community
My golden torch cactus looks slightly etiolated after this last winter since it was cloudier than usual, I put them outside in the morning sun until this grow light came in. I hope it’ll help even out the etiolated top a little bit and start growing in fuller. I usually keep my cactus outside in the summer anyways , however I have to bring them in if it rains and I constantly battle pests. I’m going to skip it all this year and start keeping them in a tent from now on, that way I don’t have to deal with pests like mealy bugs and I can admire them at 12am instead of going outside with a flashlight like a crazy person. I have 7 more cactus that will be delivered in the next coming weeks, so I’m hoping to have the lighting dialed in so I can introduce my new desert pals. Eventually I’m going to expand my collection significantly so another light in the future will be in the works. Great quality , heavy and great size.

Pretty warm light 🥵
It's bright and it's hot. I'm pretty used to touching hot things in the HVAC field. This thing is almost too warm to touch

This light will grow Flowers and start Seedlings
As you see these plants are from use the spider farmer led grow lamp. Works great . I have used two grow seasons and a few times to start seedlings…. Great for 3x3 grow tent and perfect coverage. Easy to assemble right out of box. Great quality.

Money well spent . Works with VIVOSUN e42 controller
This light is worth the few extra bucks . Seriously I returned all of my cheap Amazon LEDs and took that money and bought this bad boy. So worth it. Just in case you have a VIVOSUN controller I think it’s E42? The sf2000 will work with it and you can use it like a smart light from the app. That’s the only thing I was worried about. It worked out for me . Regardless this light is the best it covers my 4x2 great even at 45% @ 24” high . Top notch . And it comes with dope stickers 😁😎
