A number of powered lighting blocks would be useful.
- a basic status indicator lamp that is red when not powered and glows green when powered (luminance 7?)
- this would not draw power itself but would operate similar to an installed EC-meter and indicate if a line is currently hot - normal electric lighting (luminance 14)
- flood lamp (luminance 15) - don't think game allows any brighter than this, which is a shame, because flipping on the generator to melt zombies with artificial sunlight is very attractive...
- additionally, lighted cables themselves would be nice (cable + indicator lamp, possibly only 6 lumens?).
To make powered lights most effective, however, it would also be nice to have a switch that powers a circuit in darkness (an anti-solar panel).
Recipes:
Status LED - glass + copper dust + insulated cable
Light Bulb - 3 tin + glass + uninsulated copper cable + insulated copper cable
Flood Lamp - 2 light bulb + 2 insulated copper cable
Lighted Cable - status led + cable
NB:
Real LED filaments are made from an alloy of gallium, which is usually found in zinc/aluminum... neither of which do we have. Tin might therefore make more sense chemically as a filament material, but copper is both redder and greener
