Mercury lamps

here's how to pick the lamps that will serve you best

In these days of energy crisis and rising costs,there's more reason than ever to chooseGENERAL ELECTRICercury la ps

The objective of this folder is to present capsu-lar information and comment on General Elec-tric mercury lamps, as an aid to lamp selection.

the energy crisis andthe cost of lightThis publication is about mercury lamps, notabout the Energy Crisis. But the present andimpending shortages of most of our importantsources of energy do have a bearing on ourmessage.And so does the fact that after so many years ofgoing down, down, down, the cost of light hasfinally started to go up-chiefly because electricpower rates have made the same reversal and aretrending upward.

The combined realities of the Energy Crisis and ofthe period of rising costs that we are in wouldseem to have inescapable implications for the userof light. The efficiency with which light isproduced, and the skill with which it is used havebecome more important than ever before, andpromise to become increasingly important in thefuture. Quite simply, this has a great deal to dowith the matter of choosing the right lamp for theintended lighting service.

descriptioMercury lamps constitute one of the families of high intensitydischarge (HID) lamps, and as such are electric arc lamps. Currentflows through a conductive atmosphere of mercury vapor that iscontained in the relatively small inner quartz arc tube, into theends of which the two current-carrying electrodes are mounted. Thearc stream is very bright. It emits both light and invisible ultravioletenergy.Like all discharge lamps, mercury lamps must be operated inconjunction with a ballast to limit the flow of current to the are,and usually to provide the proper starting and operating voltages.General Electric mercury lamps range in wattage rating from 50 to3.000.Following are some of the important characteristics of General Elec-tric mercury lamps.

clear (A)-Light has characteristic blue-green color of the mercury spectrum... emits energy in the violet, blue, green, and yellow wavelengthlines, but not in between, and not in the reds.So object colors are distorted ... people appear unnatural.Result: use of clear lamps is mostly limited to applications in whichcolor rendition is unimportant-for example, a few heavy-industryoperations, roads, highways, interchanges, loading docks, etc.Even in these, the chief advantage is the good optical control madepossible by the small light source (the arc stream).special applications:Clear mercury lamps do a beautiful job of lighting evergreens andcopper surfaces outdoors that have acquired a green patina (roofs,domes, steeples).

General Electric mercury lamps have important features of design andconstruction, features that improve performance throughout life, andadd up to more light per' dollar spent. Simplified mount structure absorbs less light (up to 4.9% less thancompetitive mounts). Full phosphor coating for maximum light output, elimination of rawmercury light show-through. (Through the 400-watt size, GE's ellipti-cal bulb shape allows 25% more phosphor surface area than the BTshape used by some competitors. In the 400-watt DX and WDXlamps, this adds well over 300 extra lumens of red light.) As noted elsewhere in these pages, advanced phosphor design forhighest light output throughout life. New "backwound" electrode design holds emission mix intact forlonger life, minimizes electrode "sputtering", which Can darken arctube, decrease light output. Long-life arc tube made with large sturdy electrodes ... quartz tubeclosed positively with extra-wide pinch seals ... large-diameter tubefor lower operating temperature. High-quality resistor (another important link in the reliability"chain") designed to withstand the high temperatures and high start-ing voltage present in mercury lamps. Nickel-coated mechanical base for durability and easy lamp

replacement (resists corrosion=no lubricant needed). Also. date-coded bases to allow user to record date of installationand keep a log of individual lamp performance.Ask your G-E Lamp Representative to translate these design andconstruction features into dollar savings in your lighting budget.
