Gloworm Lights use Cree LEDs mounted side-by-side. The?XS 2500?housing has three bulbs while the?X2?has a pair. Both ship with a variety of mounting options. A quick release can screw into the side of the light and clamp around the handlebars, or a GoPro mount can be used on a helmet.
Both lights include a 4-cell battery. The XS 2500 promises two hours on the brightest 2500-lumen setting and 36 hours at the lowest 200-lumen setting. The 1700-lumen output of the X2 will last three hours on high or up to five days at 100 lumens (I didn?t try leaving it on for five days).
All Gloworm lights ship with four specific levels of brightness, but thanks to Intelligent Mode Technology (IMT) these settings are completely customizable using?these steps. The XS and XS also include a 2-button wireless remote. Assuming you have two lights, you can control both of them simultaneously with the same button or operate them independently using both buttons on a single remote
