Don't have a Magcharger but do have the GL4/M90. It is one bright light, not a whole lot larger than a Streamlight stinger (head is wider, little longer) but has an 80 minute run time and is way brighter than the stinger. Has about the same brightness as the Ultrastinger but a more diffuse beam. at an equal distance it will light up virtually the whole side of a building while the Ultra will only light up the door.
