Visionsmith has set out to build a drop-in solution for most popular halogen fresnels. If you have a halogen kit, this is for you. This isn’t anything like an LED retrofit, it’s just a bulb swap. So upgrading to LED is no longer a process of throwing out all your old favorite lights, and rewiring to support the new expensive LED Fresnel’s. Now you can literally just upgrade from a halogen lamp to a ReLamp LED. It’s much faster. There is no rewiring at all. It costs four times less in most cases. You still get all the benefits of LED.
