Birch Aquarium offers light bulb exchanges

On four upcoming Saturdays, Birch Aquarium at Scripps Institution of Oceanography will be trading new, energy-efficient light bulbs for old light bulbs and torchiere lamps. The trade is free and participants also get 2-for-1 same-day aquarium admission.

On April 19, June 21, July 19 and Aug. 16, San Diego County residents can exchange up to five 75-watt or higher incandescent light bulbs and/or up to two halogen torchiere lamps (bring entire fixture) for compact fluorescent lights - a combined savings of more than $100 - while supplies last.

The new models use 75 percent less energy than regular incandescent bulbs, create 75 percent less heat and last 10 times as long. Also, people can bring expired compact fluorescent bulbs to the event for proper disposal.

Participants must a bring a copy of their current San Diego Gas & Electric utility bill and/or a California ID to prove San Diego County residency.

Once inside the gates, visitors can explore Birch Aquarium at Scripps’ newest exhibit, Feeling the Heat: The Climate Challenge. Through hands on-activities, videos and visuals, participants learn the scientific facts of climate change and discover tips for reducing carbon emissions.

Birch Aquarium’s light bulb exchanges run from 11 a.m. to 3 p.m. outside the aquarium entrance and are offered through a partnership with SDG&E and the city of San Diego.

Dates are April 19, June 21, July 19 and Aug. 16.
