1. It is referred to as the lamp produced by putting mercury inside of the lamp.
2. Suitable for the resin required only for a single wavelength as the wavelengths occurred consequently in vicinity of the main wavelength are small.
3. Main wavelength is 365mm and sub wavelength output 253.7, 294.7, 302.2 and 404.6mm etc.
4. Compared to other lamps, as it has a higher output of short wavelength UV and the wavelengths occurred consequently in vicinity of the main wavelength are small, it is suitable for the resin required only for a single wavelength
