Firefly Tech

Firefly Tech is an advertised "technology" popularized with the Rayven CS-18 and the Lumitron and used throughout the Light It Up sub-series.

Details
Firefly Tech allows for Glow-In-The-Dark Darts and Glow-In-The-Dark Discs to be "charged" while they are being fired or held. These clips requires three AA batteries to operate the Firefly Tech clip. Blasters with Firefly Tech or Firefly Tech clips are the only blasters that come with the ability to charge and fire glowing darts.

Trivia

 * The name may be a direct reference to the Firefly REV-8, which was one of the first blasters to use glow-in-the-dark darts.
 * Like the Super Soaker Storm Series' "PowerSoak Technology" and the Nitron's Centerfire Tech Electronic Scope, it is likely that the "Tech/Technology" part of the title is purely for show.
