Two years ago, we told you that the metal halide bulbs, which were lit 24\/7 in the Lot 50 parking garage, were converted to LEDs — a move that saved the med center $48,000 a year in electricity charges.
\n

We’re amped<\/i> to tell you that the money saved was paired with an Omaha Public Power District rebate program to purchase more LED fixtures\/bulbs and continue the savings.

Lightbulbs are often sold by wattage, and we’ve learned to associate that with light. More watts does mean a brighter bulb, but it’s actually a measurement of the amount of energy you are using. A 75W bulb uses 75 watts of electricity, but puts off about 1,100 lumens of light. LEDs emit the same number of lumens using substantially less watts. The light comes from small diodes, so they are easily dimmable, can be warm or cool, change colors and emit less heat, thereby reducing cooling costs. That control allows for daylight harvesting<\/a> and motion-sensing so lights are only on, and as bright, when they need to be.

Since that time, lights\/fixtures have been replaced in:<\/p>\n
