I am using this light to cure SMD Sunflash fiberglass resin and it WORKS. I can't say exactly how fast it works because I haven't timed it, but I don't feel like I'm waiting for my beard to grow using it. For now I just throw it in before my work, but later I plan to build a vented curing chamber. If you are looking for UV light curing SMD resin, this one will work. I was understandably skeptical when I bought it, but so far it's been great to use - just don't let the heatsinks hit anything as they get hotter than 'heat'. My only knock that doesn't deserve to be removed. All stars are - I would ask for a switch (if I missed something). I have to repeatedly turn this light on and off when using or not using it, which becomes tedious when I'm switching between curing and laying fiberglass. Of course, I don't want to activate the resin while I'm applying it, so I turn off the light just to be safe (instead of just pointing it out of the way) and I feel like leaving it on will only shorten the overall run time before I start to burn out the LEDs.
