Trinity Church LED retrofit reduces electricity 95%

Trinity Church 12W LED Retrofit Kit Replaces 300W Halogen
Saves 95% Electricity with Improved Light output

Trinity Church in New York City wanted to reduce energy expenses and reduce the frequency of lamp replacements. One big headache was a set of Halogen wall washers that they used to illuminate the foyer area of one of their office buildings.

These wall washers use 300W Halogen lamps, with rated lifetime of 2,000 hours, which needed to be replaced a couple of times a year. American Green Lights analyzed the current light fixtures and determined new generation LED Arrays were the best option.

The original fixture was tested. The 300W Halogen lamp consumed 224 Watts of electricity, and produced 6600 lux at 18 inches. 2700K color temperature LEDs were used to match the color of the halogen lamps. Utilizing light meters to match the current light output, high output LED arrays were installed on a custom heat sink and tested. Surprisingly, 4 units of 3 Watt arrays produced greater light output than the Halogen.

The photo above shows that the 12W LED is equal or better light output than the halogen.

Summary of results:

• Measured electricity consumption: 12.4W LED vs 224W halogen
• Measured Power Factor: .998 LED vs 1.0 Halogen
• Lamp Temperature: 47 degrees C LED vs. 300+ C halogen
• Light Output at 18 inches: 6600 lux LED vs 6200 lux halogen

LED information:

• 4 units of LED array modules of 3W-5W capability each, powered at 3W each (we underdrive each LED to extend product lifetime and minimize lumen degradation
• LED arrays rated for 119 degree C maximum operating temperature. Temperature measurements show operation with these heat sinks inside this fixture does not exceed 47 degrees C.
• Color Temperature: 2700K
• Color Rendering Index: 80+
