A bright idea

A museum volunteer prepares to change out a ceiling-mounted light bulb.
There are many elements required to create a successful exhibit space, but few are more impactful than lighting.  When the Museum's Train Shed exhibit and collection storage building was built, it was illuminated with High Intensity Discharge ("HID") lamps.  They represented the best compromise for cost versus light quality.  Yet just nine years later, there are many other options, and most use substantially less electricity.

With the Covid 19 crisis closure coupled with damage to the Train Shed roof mentioned in the last post, June seemed like the perfect time to retrofit electrical lighting fixtures to Light Emitting Diodes ("LED") lamps.  

Changing out lamps is very impactful because the boom lift needed to perform the work requires exhibits to be dismantled, and cars or locomotives to be moved.  This process normally generates weeks of disruptions - except right now the Museum remains closed because of the Covid 19 crisis.  

Thanks to volunteer Arnie L. and the local Platt Electric in Preston, a conservation rebate reduced the price of the new lighting elements to roughly the cost of new HID bulbs.  Also helpful was some assistance with equipment from CHG, the company who is performing the storm damage repairs.  And especially to Arnie L. who rode the lift to the ceiling and changed most of the 38+ ceiling fixtures.  Brent assisted with the conversion as well, and more than a dozen others helped with dismantling exhibits, removing the old ballasts, and helping provide supplies for the retrofit wiring.

With thanks to everyone for working together, all the Trains Shed HID high bay ceiling fixtures were successfully converted to LED lamps.  This cut the power consumption by approximately 25% and "warmed" the lighting color temperature to 3,000 K, which is also known as warm white.  This will generate annual power savings of approximately $2,000, and improve the visitor experience immensely.

Well done Arnie L. !
