The lighting at the BWI Airport Marriott had several problems.  Many of the conventional bulbs were failing and with the main lobby ceiling at 25 feet high, it required special equipment and maintenance personnel to change a single light bulb. Additionally, rising maintenance costs were also a concern.

The hotel operates their lobby lighting 24 hours per day, 365 days per year. Prior to the LED retrofit, the lobby was using 230 MR16 halogen bulbs at 50 Watts each and 90 PAR38 incandescent bulbs at 90 Watts each. These bulbs required constant maintenance and increased room temperatures due to their heat output. The management felt it was imperative that a solution was found and LED lighting was the clear choice.

LED Source® provided several solutions to the Marriott. All of the 320 conventional and inefficient bulbs were replaced with state-of-the-art Lighting Science LED lamps - PAR38 at 18 Watts and MR16 at 6 Watts. This provided an estimated 84% savings in energy consumption. In addition, the retrofit improved light levels and also reduced both maintenance and air conditioning costs.
