    I bought the X3 500 do it yourself Ki last month. This light is as good as the X4 600 that I bought last year. I bought the light to replace two Sunco 80 watt purple lights. I wouldn’t have bought these lights if they didn’t meet all of my needs. The light is fantastic and fits in a 4 x 2 tent perfectly. It does not need full power to get great growth. The kit is easy to put together, however I think the commercial units are better because of the push lock connectors, a better dimmer switch and the warranty.
    I do not regret purchasing this light. This light is as good as the other one I have. I would highly recommend that anyone looking to purchase a high-quality light not to keep looking and buy a Chilled product.

    My light arrived ahead of schedule, was easy to assemble, and is super duper bright.
    The construction feels solid and designed well. I highly recommend ChilLed products and I think I will be ordering again in the future.
    My plants are also very happy.
