Halogen Safety Information
? Burn Hazard
- Lamp surface operates at 400-500°F (204-260°C)
- Allow 15 minutes cool-down before handling
- Do not touch glass with bare hands (oils cause hot spots)
- Use clean cloth or gloves for installation
- Keep combustible materials 6+ inches from lamp face
⚠️ Pressure Rupture Risk
- PAR38 lamps operate under internal pressure
- Do not use if glass is scratched or chipped
- Do not exceed rated voltage (120V only)
- Use in fixtures rated for PAR38 halogen
- Shield from direct rain unless fixture is wet-rated
? Handling Tips
- 2850K warm white enhances skin tones and wood finishes
- Fully dimmable with standard incandescent dimmers
- Instant on - no warm-up time
- CC-8 filament provides stable beam pattern
Halogen vs LED: 75W PAR38 Comparison
| Feature | This GE 75W Halogen | LED PAR38 Equivalent | Consideration |
|---|---|---|---|
| Wattage | 75W | 10-15W | LED uses 80% less energy |
| Initial Cost | $6-8 | $15-25 | Halogen lower upfront cost |
| Lumen Output | 1,050 lm | 1,000-1,200 lm | Comparable brightness |
| Color Rendering (CRI) | 100 (Perfect) | 80-90 (Good) | Halogen superior for art/retail |
| Dimming Performance | Excellent (0-100%) | Variable by model | Halogen dims smoothly |
| Warm-up Time | Instant | Instant | Both immediate full brightness |

Frequently Asked Questions
What is the difference between PAR30 and PAR38?
PAR38 (used in this GE 14748) has a 4.75-inch diameter and is typically 75W-120W, suitable for outdoor floodlights and high-ceiling indoor fixtures. PAR30 is smaller (3.75-inch diameter), usually 50W-75W, and fits standard indoor cans. PAR38 provides more light output and wider beam spread but requires larger fixtures. Always verify your fixture's maximum diameter before ordering.
Can I use this halogen lamp in a standard light socket?
Yes, the E26 medium base is the standard screw-in base used in most US household fixtures. However, ensure your fixture is rated for PAR38 size (4.75" diameter) and can handle the heat generated by 75W halogen (400°F+ surface temperature). Do not use in plastic socket fixtures or enclosed fixtures without adequate ventilation.
How many lumens is a 75W PAR38 halogen?
This GE 14748 75PARHFL25 produces 1,050 initial lumens. Beam angle affects perceived brightness: the 25° flood concentrates light into a specific area, creating higher foot-candles (illuminance) than a wide flood of the same lumen output. For comparison, a 75W incandescent A19 bulb produces about 1,100 lumens but spreads it in all directions.
Is 2850K too yellow for outdoor security lighting?
2850K warm white is preferred for residential outdoor lighting because it reduces glare and light pollution compared to cooler temperatures (4000K+). It provides excellent color rendering for identifying faces and vehicles while being neighborhood-friendly. For commercial security requiring maximum alertness, 3000K-4000K might be preferred, but 2850K is ideal for home security and ambiance.
Why does my PAR38 bulb keep burning out quickly?
Premature failure is usually caused by: (1) Voltage fluctuations - verify 120V supply (not 130V). (2) Fixture vibration - garage door openers and machinery cause filament failure. (3) Fingerprint contamination - oils on glass create hot spots. (4) Enclosed fixtures - excessive heat buildup. (5) Dimmer incompatibility - ensure dimmer is rated for 75W halogen. This GE lamp should last 2,500 hours (3 hours/day = 2.3 years).
