I just got a Viridian X5L Gen 2 from Xfighterdefense.com the owner is prior service and offers discounts to Military customer past and present. I had great service from him and when I had a question he called me personnally! He has excellent customer service and knows everything about Viridian products! I highly recommend him! I bought the viridian as opposed to compareable lights from surefire and others because of the green beam, and prior use of other Viridian products and the ECR which turns the unit on upon draw, then turns the unit off when re-holstered no other weapon light has this feature that I know of. Excellent product!
