  1. Great product 5 Star Review

    Arrived on time and in perfect condition

  2. Bright, clean light 5 Star Review

    Posted by on 29th May 2019

    I've only plugged in these lights today so I can't attest to their longevity yet.
    They arrived in perfect condition, wrapped sufficiently in many layers of cardboard and padding. They plugged in very easily to the fixtures I bought from this site. I'm very happy with the light they emit - A clean bright white light.
    I don't have a UV meter so unfortunately I can't take readings. In six months I'll be reordering these bulbs again!

  3. Love this product! 5 Star Review

    Great quality bulb with a great UVB output! Even placed atop a screen tank lid I'm getting a great UVB gradient read (for a bearded dragon) that goes right to the bottom of my 24'' high tank. This makes it easy for a reptile to comfortably manage his exposure, while making sure he can get what he needs.
    I also strongly recommend a Solarmeter so that you know exactly what you are doing when managing UVBs, especially when dealing with powerful lamps and reptiles that require higher amounts than most others.

  4. Perfect for a Beardie 5 Star Review

    While you must have 15” from the light to the dragon (need a large enclosure) this light is top notch! Our dragon is out more and more active and even eating his greens. So happy to have found it! Great company too!!

  5. Great UVB! 5 Star Review

    Perfect lamp for rehabbing a beardie with MBD. You need to be careful and a UV meter is recommended to ensure the correct exposure. Have had the tube for the last 2-weeks and already showing improvement. Todd is great to deal with and he is quick to answer any and all questions you may have. I highly recommend this product and Light Your Reptiles as a reputable vendor
