Birch Aquarium offers light bulb exchange

Join the global effort to slow climate change and cut down your energy bill at the same time. On four select Saturdays at Birch Aquarium at Scripps Institution of Oceanography, UC San Diego, trade in old light bulbs for new, energy-efficient models - for free - and get 2-for-1 same-day aquarium admission.

On April 18, June 20, July 18 and Aug. 15, San Diego County residents can exchange up to five incandescent light bulbs for compact fluorescent lights, while supplies last. CFLs use 75 percent less energy than regular incandescent bulbs, create 75 percent less heat and last 10 times as long.

Participants also will receive a free Home Energy Savings kit that includes an energy-efficient low-flow showerhead, two faucet aerators for the bathroom and one faucet aerator for the kitchen.

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.

In addition, expired CFL bulbs will be accepted at the event for proper disposal. In California, CFLs cannot be disposed of in regular trash or recycling bins because of trace amounts of mercury contained in the bulbs.

Birch Aquarium’s light bulb exchanges are held 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.
