1.5V bulb
Reviewed By: Paul Q. 
I ordered twelve 1.5V bulbs for student electric circuit set-ups for a school science workshop (plus the associated bult sockets). The bulbs worked well, much better than the lights I got elsewhere. One word of caution - order extra bulbs - three arrived with broken filaments - I don't know if that is unusual but it was a pain in the behind. I should have ordered a few extras just in case. Highly recommended.
