have been wanting to try led. but I don't want to buy something that is wowrthless.

I like that the HEI lenses can deliver the light uniformity and color mixing of a halide T5 combo without sacrificing the power and efficiency of the LEDs.
The HEI lense are awesome. I currently own 2 of the gen3 pros hopping you guys would possibly start an upgrade kit for these. After many years of thinking i finally pull the trigger on the gen3 only to find out they were coming out with the gen4. I shouldve waited but oh well it is what it is. Still a great light!
