Eurostar 12 Volt MR16 GU5.3 Base without front glass has a reflector that utilizes a multilayer titanium oxide coating which is more durable than standard dichroic coatings. The thickness of this coating ensures that they do not crack or peel under the stress of high temperatures. Opposed to other lamps which range from pink to orange due to an inferior coating, Eurostar MR16 lamps maintain color from lamp to lamp and throughout the life of the lamp. Features axial filament for precise beam control. Average lamp life 5,000 hours. Available in 20, 35, 50 and 75 watts with 12, 24, 36 and 60 degree beam angles. 3000K Warm White color temperature.
