Having a 60W equivalent bulb strapped on the truck has inspired the lion kingdom to create a flashlight out of a 100W bulb. The mane problem with such a thing is the reflector. The bare LEDs are quite diffuse. Commercial flashlight reflectors are too small.
Even the diffuse light from the 60W has proven better than a single LED flashlight or a phone. An alternative is just carrying around a full size lampshade with the original form factor bulb. A fresnel lens might do the job.
