DO YOU NEED SHATTER SHIELDED LAMPS?

For over thirty-five years we have been manufacturing superior shatter shielded bulbs. We were the first to seek and acquire USDA approval for shatterproof lamps.

Glass Surface Systems specializes in plastic-coated and Teflon® Coated shatterproof lamps & bulbs. We have always been the leader of the safety-coated lamp industry, our research and development of new lamp and bulb coatings and coating techniques for a variety of industries and applications have extended our reach into bottle coatings, and flask, test tube and other specialty Silicon coatings, Teflon coatings as well as new and proprietary coatings and plastic coated products.

Over the years we have produced millions of safety lamps for food, beverage and drug industries and other manufacturers looking for the best protection you can buy. Our products include Incandescent Bulbs, Halogen Bulbs, LED Exit Lamps, Compact Fluorescent, Fluorescent Tubes, High Intensity Discharge, High Pressure Sodium, Appliance bulbs, Electronic Ballasts

Bulb Identification Charts

Incandescent :

Bulb Types: A bulb designation consists of a letter to indicate the shape and a figure to indicate the approximate diameter in eighths of an inch. Bulbs are measured through their greatest diameter in eighths of an inch. Thus, an F-15 bulb is a flame shape, 15/8 of an inch or 1 7/8 inches in diameter.

Filament Types: A filament designation consists of a prefix letter to indicate whether the wire is straight or coiled, and a number to indicate the arrangement of the filament on the supports. Prefix letters include: C (coiled) - wire is wound into a helical coil or it may be deeply fluted; CC (coiled coil) - wire is wound into a helical coil and this coiled wire again wound into a helical coil.

Base Types: Typical screw base is shown. One leaden wire is soldered to the center contact and the other soldered or welded to the upper rim of the base shell. Base shells are typically made of brass or aluminum. ANSI designations are in parentheses.

Fluorescent:

Bulb Types: The bulb shape and size of a fluorescent lamp are expressed by means of a code consisting of the letter "T" (which designates that the bulb is "tubular" in shape) followed by a number which expresses the diameter of the bulb in eighths of an inch. They vary in diameter from T-2 (1/4 inch) to T-12 (1 1/2 inches). In nominal overall length, fluorescent lamps range from 6 to 96 inches, which is always measured from back of lamp holder to back of lamp holder. For example, the actual overall length of the 40 watt rapid start T-12, 48 inch lamp is 47 3/4 inches. Circle line lamps, which are circular, are available in four sizes: 6 1/2 inches, 8 inches, 12 inches and 16 inches outside diameter. There are also U-shaped fluorescent types with T-8 and T-12 bulbs. The width of U shaped types are measured for the distance between the ends. The overall length is measured from the face of the bases to the outside of the glass bend.

Base Types: For preheat and rapid start fluorescents, four electrical contacts are required, two at each end of the lamp. This is accomplished in the standard line of lamps by the use of a miniature bipin for T-8 and T-12 bulbs and mogul bipin for T-17 bulbs. In circle line lamps, the cathodes are connected to a four-pin base located between the junction of the two ends of the lamp. High Output and Very High Output lamps have recessed double contact type bases. Slim line (Instant Start) lamps require only two electrical contacts, one at each lamp end and have single pin bases.

All compact fluorescent lamp bases shown have 2 or 4 pins. The 2 pin lamps are designed for preheat operation, with lamps having an internal starter. The 4 pin lamps are dimmable and are designed for electronic ballast operation; these lamps have no internal starter.

HID (High Intensity Discharge) :

Bulb Types: A bulb designation consists of a letter to indicate the approximate maximum diameter in eighths of an inch. Thus, an ED17 is an Ellipsoidal Shape, 17/8 of an inch or 2 1/8 inches in diameter.

Base Types: Lamps with screw bases have one lead-in wire soldered or welded to the center contact and the other soldered or welded to the upper rim of the base shell.

Bases with ceramic bodies have internal leads welded to either silver plated contacts or external lead wires.

Base Types: Typical screw base is shown. One leaden wire is soldered to the center contact and the other soldered or welded to the upper rim of the base shell. Base shells are typically made of brass or aluminum. ANSI designations are in parentheses.
