So far, we sat at the Dresden night skating the Mag-lite with a two Bayzellen and color attachment to secure the event. For testing we used the ST2P016. Undeniably they are more light than lamps with round cells and the standard bulb, but it is due to the larger diameter and larger weight much more cumbersome. For a time of the lamp a few minutes using no problem, but less suitable when used over several hours.
