ConstantColor® Technology
GE's ConstantColor® reflector coating delivers consistent clear white light throughout the lamp's rated life. Unlike ordinary MR16 reflectors that produce murky, greenish light as they age—discoloring illuminated objects—ConstantColor® maintains:
- Stable color temperature at 3050K from first hour to last
- High lumen maintenance — over 90% light output throughout life
- No greenish tint that affects merchandise and artwork appearance
- Consistent beam quality with smooth, even distribution
Performance & Benefits
- Superior Color Consistency: ConstantColor® coating prevents the greenish tint common in aging standard MR16 lamps
- UV Protection: Cover glass filters UV radiation—safe for sensitive displays and artwork
- Precise Beam Control: 25° narrow flood provides focused illumination with minimal spill
- Long Life: 6,000-hour rated life exceeds standard MR16 lamps (typically 2,000-4,000 hours)
- High Intensity: 2,900 CBCP delivers strong center beam for accent and display lighting
- Universal Burning: Operates in any position for flexible installation
- Dimmable: Compatible with standard low-voltage dimmers
Recommended Applications
- Retail display and accent lighting
- Museum and gallery illumination
- Hospitality lighting (hotels, restaurants)
- Architectural accent and wall washing
- Track lighting systems
- Recessed downlighting
