At nine-tenths of a watt, the H&H Ultramaster LED Exit Sign Retrofit is the most economical exit lamp you can use.
Replacing a 9 watt compact fluorescent plus 3 watt ballast, two Ultramaster LEDs save 83% in energy and, at 10¢ per kWh, cost only $1.58 per year to operate—compared to over $10.00 for the CFL and more than $35.00 for an incandescent sign.
What's more, the Ultramaster LED is life rated at an astounding 250,000 hours—over a quarter century of continuous burning. Maintenance and replacement costs are virtually non existent. You literally install them and forget about them. Your exit signs will always be lit—in brilliant red—in case of emergency.
Ultramaster LEDs screw into all existing single and doubled faced candelabra based exit signs. (Intermediate, medium and bayonet adapter bases available.) Installs in minutes.
Ultramaster LEDs comply with all OSHA and NFPA requirements and exceeds IEEE 587 and A.N.S.I C6241. It's covered by H&H's 10 year, "no-nonsense" Free Replacement Warranty.
Over the estimated 25 year life of the H&H Ultramaster LED Exit Retrofit, the total operating cost is only $39.50 ($1.58 x 25). The cost of operating one incandescent sign for the same period is $1,913.25, a difference of $1.873.75 per sign. The cost of operating a compact fluorescent sign is $721.00, a difference of $681.50. Multiply the differences times the number of signs you have operating and see how much you can save.
