The GE DDL halogen lamp (ANSI code DDL) is a projection/optical lamp with a dichroic MR16 reflector (Ø51 mm, GX5.3 base). It delivers a bright white beam at 3150 K with near-perfect colour rendering (CRI ~100), designed for precision optics.
Powered at 20 V by the equipment's built-in transformer (slide projectors, overhead projectors, enlargers and optical devices), it is not an ordinary 12 V lamp: use it only in the device rated for this voltage. Its dichroic "cold-light" reflector throws light forward and lets heat pass to the rear, protecting slides and specimens.

Frequently asked questions
What voltage does it run on?
20 V, supplied by the device's built-in transformer/power supply (projector, microscope, illuminator). It is not a 12 V lamp: do not connect it to a standard 12 V halogen transformer.
Which equipment is it for?
For slide projectors, overhead projectors, enlargers and optical devices. Check the ANSI code DDL and GX5.3 base marked on the lamp or in the device manual.
What does the dichroic reflector do?
It reflects visible light forward and lets infrared (heat) pass to the rear: the projected beam is "cooler", protecting slides, film and specimens.
How is it replaced?
Two-pin GX5.3 base: with the device off and the lamp cold, remove the old one and push the new one into the socket. Avoid touching the small quartz capsule with bare hands.
