Photontek 300W Pro LED

Lights been nothing but fantastic I couldn’t be happier with my purchase. Plus it’s compatible with the controller 69 with a TJ-11 adapter with more dimming options.

Growace for the amount of times you emailed me to review this light before I could even get it hung up you should sponsor me already.

In all seriousness Growace is great and fast shipping. Quit using Amazon and support the industry. Growace always has the best pricing.
