The Hi-Tech Lamps part number FNE/CG-U is a 50 watt (50W), 12 volt (12V) Popstar?? MR-16 reflector halogen lamp made by Ushio. Ushio’s Popstar series of lamps provide colors without the added expense of colored filters and gels. The highest quality dichroic coatings are applied to the front cover glass of these MR-16 lamps to provide deep color saturation. Computer controlled alignment of the axial filaments in the Popstar lamps allow precise beam control. All of the Popstar lamps have UV protecting quartz used for the bulb wall to protect both the dichroic filter and the illuminated subject. It utilizes a high quality multilayer titanium oxide coating process, with results that are much more consistent and durable than standard dichroic coatings, ensuring reflector coatings do not crack or peel under the stress of high temperatures and maintain color from lamp to lamp and throughout the life of the lamp. This lamp has maximum overall length of 45mm (1.78in) and it has a green cover glass. The average lifetime is 4000 hours. This lamp has a color temperature of Kelvin (K), and has an output of approximately 4400 candelas (4400cd). This lamp is also known as Ushio FNE/FG and 1000584.
