The app allows you to control the brightness and the on/off function. Went right onto the bamboo post in my orchid rocket. The light bulb itself is small but it puts out plenty of light.

This is perfect for a grow light for starters. Hung this in my greenhouse cabinet. The peppers seem to love this light.

This thing is a lil beast. Waiting for another sale to scoop up another one. Pictures are of my current setup.

I have another 65 watt light and it's a bit brighter, maybe like 1. It is very bright. Good build quality, and the adjustable brightness is wonderful. I know it doesn't use top of the line led beads, but it uses twice as many cheaper ones.

The dimmer is very functional and very handy. The built in fan helps to disperse the heat effectively.

Lights shut off when the dial is turned under 20%. What a disappointment.
