Fireflylite (formerly Fireflies) are a small manufacturer of lights, first established in 2019. Recently, Jack, the owner of Fireflylite, has been reworking their product range with a variety of new models. These lights fall solidly into the enthusiast category, being generally 21700-based lights than run Anduril, the enthusiast firmware of choice.

The E07X Canon (broadly referred to as the E07X here) is one of the newest series of lights, first being released in December 2023, replacing the older E07X Pro and original E07X. This is a single 21700 light, on the large side but overall within EDC size, with a focus on high output, and enthusiast-oriented features like Anduril, and aux LEDs. Recent models have been using the lume1 drivers developed by loneoceans, with the E07x using a buck+FET driver.
