Excellent quality. I was looking at similar units for over $2000 thought I’d take a chance. Glad I did. The one thing I found out is you absolutely need a 30 amp breaker in your breaker box to use all three lights at the same time. If you only have 20amp just use two of the lights at the same time. Flash off feature is nice. You can program the unit to use the flash off feature for a certain amount of time and then it will automatically turn off or you can set it to go on for cure mode for a certain amount of time and then the unit will cycle and turn off by itself.
This is a short wave light and if you’re used to a medium wave light like I was you will notice it takes a little longer to get the surface temperature of. Although this unit is fast it’s just not as fast as a medium wave light in my experience. I’m using this in my auto body shop for curing paint and also using it in my vinyl wrap shop for removing old vinyl wraps and post heating completed wraps.
