With all bulbs it is beneficial to wipe the glass with dry tissue to remove surface film that may occur over time, and could reduce brightness. OVER-VOLTING MR11: Our 6V MR11-C bulbs are designed to be very bright and white when run at 6V. Unlike some bulbs on the market, they should not be "over-volted". FROSTED GLASS: Halogen bulbs with push-in and screw-cap bases can be supplied with an optional frosted finish for even illumination. Adding (F) to the bulb code indicates frosted, eg GH44(F). Some Vistalite cycle lights were supplied with frosted bulbs. Other applications are slide viewers, back lighting and models. TOUGHNESS: Halogen bulbs with push-in and screw-cap bases are suitable for rough and demanding conditions. They have been successfully shock tested at 40G in the axial and lateral planes for emergency lighting in military aircraft. DIMENSIONS: Bi-pin G2.5 are 5mm diameter, and the length of the glass is 16mm (excluding pins). Bi-pin G4 are 8mm diameter, and the glass length is 24mm (excluding pins). Screw-cap (MES) are approximately 26mm long overall. Push-in are approximately 29mm long overall. MR11-C are 35mm diameter reflector bulbs and are all fitted with a cover glass for outdoor use.
