Tech Talk from our Founder: Using the same 2" diameter housing as the Glenda, we have packed 2000 plus lumens into each light while still utilizing very little power. The younger "Twin" to Glenda, Darla is now brighter and has a bit of attitude compared to her sister. Hundreds of mounting options mean these lights can be used on a wide variety of vehicles. This light is surely going to turn heads. Darlas will make you more visible to other drivers while illuminating your route at night. You won't believe how bright she is. Specifications: 24 watts consumption each (on high). 2" diameter. High power. 2000+ lumens each. 7 ounces. Fully dimmable. Includes wiring harness. Custom tooled optics. CNC machined. Made in the U.S.A.
