Very good. Wavelength may be slightly off by +/- 2 to 5 nm, because can't trust description text vs other wattage LEDs of same blue, same brand. You will need larger heatsink, paste, and fan for full power operation. Dimmable. I bought a cheap adjustable Voltage (0-30) and adj Amperage "regulated" power supply (PS) and I can adjust brightness easily, once the threshold voltage is reached 22 V. Wattage (bc of voltage max) of PS cannot push the LED to its max wattage, but for my budget works fine. Extremely bright (you will need eye protection at full brightness). Surface of LED plane is coated with a clear "soft-ish" polymer to protect LEDs. Easy to blow clean. Easy to mount.
