While LED's appear bright their "lumens" are limited. You can make your own sets (I'll post a supplier if there are crafty folk) the units have 90' 60' 30' 15' lens narrow to broad.

This should make the Mister Happy.

My father's home was originally lit with carbide lamps - several 100 pound canisters (empty except for wheat samples) still exist on the homeplace.

I have three Justrite brass that have seen heavy, dependable use.
