GE 18633 100PAR/HIR/FL25 - 100W HIR PAR38 Halogen Lamp, Flood 25°, 2900K, 3000hr Rated Life, E26 Base
The GE 18633 100PAR/HIR/FL25 is a GE HIR PAR38 halogen lamp (3000-hour energy-saving HIR), rated at 100W (std) / 88W (extended-life, 120V) with a Flood 25° beam, 2900K color temperature, and an average rated life of 3000 hours (std) / 6000 hours (extended-life, 120V). This is a dual-rated lamp: operated at 130V it delivers the standard wattage/lumens/life shown first; operated at 120V (extended-life mode) it delivers the lower wattage/lumens at the longer life shown second.
This lamp should be selected by matching the GE catalog code, wattage, beam angle, and color temperature to the existing PAR38 lamp or fixture being replaced.

Product Overview
GE’s PAR38 halogen lamp family uses a Precise Optical System (multi-faceted reflector and lens lenticule design) to eliminate hot spots, sharpen beam cut-off, and focus more light on target than earlier PAR38 designs. The HIR line (3000-hour energy-saving HIR) is built on this optical platform in the familiar PAR38 shape and E26 medium screw base, making it a direct replacement for standard PAR38 halogen and incandescent lamps.

- Wattage & Voltage: Confirm the fixture is rated for 100W (std) / 88W (extended-life, 120V) at 130V (std) / 120V (extended-life, 120V).
- Beam Angle: Confirm Flood 25° matches the intended application.
- Base Type: Confirm the fixture accepts a standard E26 medium screw base.
- Dual-Rated Operation: This lamp’s life/wattage/lumens vary by supply voltage (130V standard vs. 120V extended-life) — confirm which mode applies to your installation.
Safety & Installation Guidelines
- Qualified Installation: Install and service only with power disconnected, following applicable electrical codes.
- Enclosed Fixtures: Use only in fixtures rated for enclosed operation if the lamp will be fully enclosed; halogen lamps run hot.
- Handling: Avoid touching the lamp envelope with bare skin; oils can cause premature failure — clean with isopropyl alcohol if contacted.
- Glass Envelope: Do not operate with a cracked or damaged outer lens; discontinue use if the lamp is damaged.
