Key Specifications
Product Overview
The GE ConstantColor® Precise™ 20-Watt MR16 HIR Halogen Lamp (Order Code: 77900) combines advanced HIR (Halogen Infrared) technology with GE's proprietary ConstantColor® coating to deliver exceptional energy efficiency and light quality. This innovative lamp uses an IR-coated capsule that recycles heat back to the filament, allowing 20 watts to deliver the light output of a standard 35W MR16—saving 30% in energy costs while maintaining crisp, white light.
Perfect for demanding commercial applications, the lamp features a UV control filter that virtually eliminates UV-B and UV-C radiation, making it safe for sensitive artwork, fabrics, and merchandise. The precise 10° narrow spot beam with 6,000 CBCP provides intense, focused illumination exactly where needed.

HIR Technology: How It Works
HIR (Halogen Infrared) technology uses a sophisticated infrared-reflective coating on the halogen capsule. This coating:
- Recycles infrared heat back to the filament, maintaining optimal operating temperature
- Reduces energy consumption by 30% compared to standard MR16 lamps
- Maintains light output equivalent to higher-wattage standard lamps
- Extends lamp life while delivering consistent 2900K color temperature
Result: 20W HIR = 35W Standard MR16 performance with significant energy savings.
Performance & Energy Saving Benefits
- 30% Energy Savings: Uses only 20W to replace standard 35W MR16 lamps
- Quick ROI: Energy savings often pay back lamp cost within one year
- ConstantColor® Coating: Maintains consistent white light throughout 5,000-hour life—no greenish tint as lamp ages
- UV Protection: IR-coated capsule plus cover glass virtually eliminates UV-B and UV-C radiation
- Precise Optical Control: Denser dichroic coating projects more light forward with minimal backlight leakage
- High Intensity: 6,000 CBCP delivers focused punch for long-throw applications
- Drop-in Replacement: Compatible with standard MR16 GU5.3 sockets and 12V transformers—no special installation required
- Superior Color Rendering: 100 CRI ensures accurate color representation
Ideal Applications
- Retail display lighting (jewelry, luxury goods, cosmetics)
- Museum and gallery accent lighting for UV-sensitive artwork
- Track lighting systems in commercial spaces
- Architectural spot lighting and highlighting
- Heat-sensitive installations (food displays, delicate fabrics)
- Residential recessed and directional lighting
Estimated Energy Savings
Based on 3 hours per day usage at $0.11 per kWh:
- Yearly Energy Cost: $2.41 (vs. $4.22 for 35W standard)
- Annual Savings: $1.81 per lamp
- Payback Period: Often less than 12 months
*Estimated yearly energy costs based on 3 hours per day usage
Safety & Handling
- Use only in fixtures rated for MR16 lamps with appropriate 12V transformer
- Keep combustible materials away from lamp during operation
- Do not use if cover glass is scratched or broken—risk of UV exposure and implosion
- Allow lamp to cool before handling—operates at high temperatures
- Turn power off before installing or removing
- Dispose of in closed container—contains pressurized gas
