Let's assume for a second that you work in the maintenance department of a slaughterhouse with several large industrial walk-in freezers. These freezers are so large that each one is equipped with cold location exit sign combos with dual 15-20 watt halogen lamp heads. During your yearly inspection of these signs, you find that many of the halogen bulbs are out. You need a quick yet cost-effective replacement solution to stay within OSHA guidelines; you need the 6V 30W sealed beam incandescent emergency light bulb!
"Whoa," you say. "But these were originally halogen?" Though halogen bulbs are brighter and last longer than normal tungsten lamps, they cost a lot more. Halogen is also incredibly bright and has been known to cause temporary blindness if shined directly in someones eyes. And since emergency lights only come on when normal lighting fails, it will still take between 6 months-2 years until you need to replace these sealed beam incandescent lamps.
These 6 volt 30 watt reflector type Par 36 bulbs have a sealed beam design which makes the LP-216 ideal for extreme cold conditions. The lamps glass envelope and brass screw terminals make them incredibly resistant to moisture and condensation. These bulbs also run much cooler than 15W halogen equivalents and give off a warm yellow glow that does not cause temporary blindness.
