NALCO carbon filament lamps - different generations
|
The two on the left are 60s or 70s, the one on the upper right is prolly 50s or 60s, the Duro-Lite/NALCO package on the lower right is the last generation from the late 70s/early 80s. The upper right bulb is most likely 30w, the other three are 10w.

However, it is really nice to keep the original package for the bulb
