    I purchased the bulb and 3 months later it stopped working. growers house took care of it by sending me a new bulb. great service. just wish there was free shipping on orders over 75.00. This is my go to site for my grow needs. (Posted on 11/25/2018)
    Very Pleased Review by J.C.
    Overall Rating
    Has been a great light for veg (4200K). Very bright, intense, full-spectrum light that doesn't give off a ton of heat. Much quicker growth and more branching than under T5 fluorescent. I have been very pleased with my purchase, it was even delivered sooner than expected. I'm flipping the girls into flower soon and just purchased the 3100K Philips CMH from Growers House.

    Great Veg Lamp, but use 3100k for flower Review by Boston Grow Haus
    Overall Rating
    Traded out my metal halide 400w for a cycloptics using this lamp. My plants are growing bushier and just seem overall healthier than using my old 400w mh. I'm also saving about 20% on my electricity over using it. Seriously switch to the Philips 3100k for flower though. It has like 10% more overall intensity than the 4200k. (Posted on 7/10/2016)
    Not much difference Review by MG
    Overall Rating
    Doesn't seem to be a drastic difference from the 3100k lamp. Slightly more white, but not as blue as the spectrum on my T5 fixture. I've only been running it for 2 weeks. I'll wait and see how the plants grow over the long term, but so far I think they responded to the 3100k better. (Posted on 2/14/2016)
