I understand it as 100 chips at 5w per. 500 is what I was expecting. It's a small grow, 2x4x4. I weave through a scrog. I've done well over the past few years with 280w of actual used power from cfl's and am looking forward to the new punch of light.
Has anybody ever used a higher wattage LED than necessarily needed, but used a diffuser to gain more coverage. I am trying it this year. I have a 2X4X4 that I will scrog under a 1000 watt "amazon" led equipped with a acrylic diffuser in place of the glass.
