Questions about this item

How much heat or power does the 1.26 W 6.3 V bulb produce during continuous use?

The 1.26 W incandescent miniature draws 1.26 watts at 6.3 volts; most of that energy becomes heat, so the glass envelope will become hot to the touch within minutes of operation.

What socket or fixture is required for the W 2.1 x 4.9 d sub-miniature wedge base?

You need a socket that accepts a 2.1 mm by 4.9 mm sub-miniature wedge base; the bulb will not fit standard bayonet, screw or larger wedge holders.
