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.
