Central Lighting, 15W LED Bulb, 1500 Lum, Warm White, 12VDC, 15W929
The LED technology used in Central Lighting products has a much higher efficacy(luminous flux per watt of power used) than other types of lighting, and is superior to most LED bulbs on the market today.
A lumen is a measure of luminous flux: quality of light that is visible to the human eye. A lumen rating is a measure of total light output in all directions, not intensity. Focusing the light into a smaller area will increase the candela rating (intensity), but not the total lumens.
