he 921 refers to the size of the bulb. The prefixes denote model number. More than you ever wanted to know about illumination is at Dons bulbs.
For LED replacements, you'll want to know the base number and possibly, the amperage rating of the fixture. The latter is not typically important as the LED replacement will draw 1/5 Amps of the incandescent it replaces. I only mention it because you may decide to use 6 Cree high-watt LEDS in your fixtures to approximate a high power flashlight. That could exceed the rating of the fixture.
Your 921 base size is T5/T10 wedge.
