I've virtually replaced my E2E with my L4 for 95% of my needs at work. There are still occasions where a little more throw is needed, but when doing close work inside cabinetry the L4 is amazing. My plant is in an outage right now and many electrical busses have been disconnected, leaving many places in the plant dark, save the emergency lights and minimal backup lighting. Using the L4 in these dimly lit areas has proved both fun and extremely useful.
I still haven't had a problem with heat. In fact I don't think it gets hot, it gets very warm. Maybe my fingers are less sensitive to heat than other people's, but I just don't have a problem with holding on to the L4, even at the head, after having left it on for 5 minutes at at time.
I may still sell my L4 and replace it with an L5 if the L5 proves to still provide a good flood of light in addition to more throw. Then I could probably replace my E2E for every task around the plant, albeit with a slightly larger package.
