Shat-r-Shield 97800 HPS400/ECOSAFE - High Pressure Sodium 400W ED18 Clear - Mogul E39 Base

Shat-­R­-Shield High Intensity Discharge (HID) lamps are designed to be safely used in open fixtures and are excellent for lighting large areas. Ideal applications for HID lamps include offices, schools, restaurants, medical facilities, retail, hospitality and general illumination. In addition to offering greater flexibility in system design, open fixtures are less expensive and more compact than enclosed fixtures. The lenses on enclosed fixtures can reduce light output by up to 10% (compounded overtime by the build­up of dirt, insects and other debris on the lens).

High Pressure Sodium Lamps (HPS)­ are the most efficient source of high intensity light and are also available in non­-cycling versions. Their efficiency is up to 140 lumens per watt and the light produced is a warm golden color. Because of their yellow light output, they are frequently used in street lighting and other areas where color rendering is not critical. Although they are not quite as energy efficient, metal halide is generally used when pure white light is needed.

The Facts on Arc­-Tube Rupture
Shat­-R­-Shield lamps have a shatterproof coating to contain glass, phosphors and mercury in the event a lamp is dropped or broken. Our coating is not designed to contain an arc­-tube rupture (“non­-passive failure”). In extraordinary applications or under certain conditions, glass fragments may escape the coating. Shat­-R­-Shield HID lamps must be burned base up only and in open fixtures only. On rare occasion, usually at the end of life, an arc­-tube can rupture and shatter the outer glass bulb and coating, resulting in the discharge of glass fragments and extremely hot quartz particles (as high as 2192ºF, 1200ºC). This is possible with all non-shrouded metal halide lamps, regardless of manufacturer. Shat­-R­-Shield protective ­shrouded lamps contain a special quartz shield which is designed to contain a ruptured arc-­tube and thereby minimize the risk.
To reduce the possibility of arc­-tube rupture and premature lamp or coating failure:
•  Operate with compatible ballast and fixture only.
•  Burn lamp base­ up only and in open fixtures only.
•  Turn lamp off a minimum of 15 minutes per week.
•  Replace lamp at or before the end of rated life.
•  Follow all instructions on the lamp’s sleeve.

Shat-­R­-Shield HID Lamp Warranty
The plastic coating on a Shat-­R­-Shield HID lamp is guaranteed not to yellow and will withstand bulb wall temperatures up to 500ºF. Except under the foregoing conditions, due to variable conditions and fixture design, Shat-­R­-Shield does not warrant or otherwise guarantee the plastic coating on HID lamps for the rated life of the lamp. The purpose of the coat­ing is to contain virtually all glass fragments, phosphors and mercury in the event the lamp is accidentally dropped or broken. Shat­-R-­Shield suggest the HID shatterproof lamps be inspected and replaced if the coating material is compro­mised due to temperature extremes.

•  The coating is not designed to contain an arc-­tube rupture.
•  Under certain conditions, glass fragments may escape the coating.
•  Lamps MUST be burned base up only and in open fixtures.
•  On rare occasion, usually at the end of life, an arc-­tube can rupture and shatter the outer glass and coating.

This is possible with all non-­shrouded metal halide lamps.
