- Using single-ended quartz halogen string capsule.
- MR16 lamps are small.
- Their 2-inch (5-centimeter) diameter allows for great flexibility, especially where luminaries size is an issue because of space constraints or aesthetic concerns.
2. Size
- MR16 lamps are small.
- 2-inch (5-centimeter) diameter
- The ceiling aperture for down light luminaries using an MR16 lamp for example it can be as small as 3 centimeters in diameter.
- These luminaries are known as pinhole down lights.
3. Transformer.
- A transformer is needed to reduce the line voltage from 120 or 277 volts to the appropriate level for these lamps.
4. Lumen maintenance.
- Two lamp components which are the halogen filament capsule within the lamp and the reflector.
- Excellent because the regenerative halogen cycle that occurs within the filament capsule keeps the bulb wall from blackening.
