Questions about this item

What base standard does the SFc10-4 interface use, and what does it cap?

The SFc10-4 base mates with matching double-ended sockets and caps the electrical connection at 400 watts.

What physical dimensions and socket type does the double-ended shape need to fit?

The double-ended lamp requires fixtures with a pair of SFc10-4 sockets spaced to accept its overall length.

How is the bulb installed, and what step is often missed?

Align each end with the SFc10-4 sockets and press until both ends seat fully; the step often missed is confirming both ends are securely latched.
