With the release of the Brickstuff EasyLight™ System and the accompanying change from our traditional “large plug” size to the new “small plug” size that is more compatible with other hobby lighting products on the market, they decided to keep the trend of “small” going and switch from AA battery packs to AAA battery packs.
 
This is the EasyLight™ 3x AAA Battery Power Pack. Included is the battery pack with on/off switch (batteries not included) and small connecting plug, and a BRANCH20 adapter with six small connecting plugs. In case you need to connect to legacy Brickstuff components with large plugs, you can purchase the connecting cables with dual-sized plugs.
 
Using this Power Pack, you can connect up to five LED lights. It’s a great way to start your lighting setup. Best of all, when you’re ready to expand, this little battery pack can power 100 LED lights or more, so you can use the parts in this Power Pack even as your lighting setup grows.

LED lights and expansion packs sold separately. Requires three AAA batteries, not included.
