  • Great product

    by chris – 17th Oct 2016

    I was looking to add some 32w Black Lights to existing fixtures that have 32 Watt ballasts
    In them. I purchased some 36 Watt ones last year from Spencer's that were just OK.
    The ones I received from SOS are much brighter and better quality than the ones from Spencers.

  • Awesome!

    These lights were amazing! The shipping was insanely fast! Theses things were packaged so good a truck could've ran over them with no damage.

  • Black Light Christmas Display

    by Dave M – 10th Dec 2014

    Bought four of these for a black light Christmas display. Big box stores are still selling the T12's, didn't want them. Product was VERY well packed, so happy about no breakage. Installed them in two two tube fixtures with High Ballast Factor ballasts. They put out very little visible light but man do they light up the display!! Very happy with the fast shipping and the great quality of the tube. Would definitely recommend this tube to anybody creating a black light display. Thanks SOS LightBulbs!!!
