*Source data title referenced 130V while the detailed specification listed 120V — these are inconsistent. 120V has been used here as the explicit spec value; confirm voltage with the GE manufacturer specification sheet before ordering, since GE PAR38 lamps are produced in both 120V and 130V long-life variants with different ratings.

Product Overview

The GE Ecomagination HIR PAR38 100W uses halogen infrared reflective (HIR) coating technology to reflect infrared energy back onto the filament, reducing energy consumption while maintaining high light output — delivering up to 28% greater efficiency than standard halogen PAR38 lamps of comparable output. GE's precise optical system, featuring multi-faceted reflector and lens lenticule designs, improves beam control across the full PAR38 lamp family by eliminating hot spots, sharpening beam cutoff, reducing stray light, and improving lamp-to-lamp consistency.

At CRI 100 and 2900K warm white, this lamp delivers full-spectrum, accurate color rendering ideal for retail, hospitality, and residential accent and flood applications where color accuracy matters. The 25° flood beam spread provides broader area coverage than a spot lamp while maintaining the focused, consistent beam pattern characteristic of GE's enhanced optical design. This Ecomagination HIR PAR38 family is also available in 50W, 60W, 70W, and 80W standard versions, with XL (extended life, 6,000 hour) versions available in 45W, 55W, and 90W.

Compatible Applications

Retail and commercial flood lighting — 25° flood with CRI 100 for accurate color rendering of merchandise and display areas.
Residential and hospitality accent lighting — Warm white 2900K output for inviting ambiance in living spaces, lobbies, and dining areas.
Energy-conscious retrofit projects — Up to 28% more efficient than standard halogen PAR38, reducing energy costs by an estimated $7+ per lamp over its life.

Before Ordering — Verify

Voltage: Confirm whether your application requires 120V or 130V — the source listing for this lamp had conflicting voltage data. Verify with GE or the spec sheet before ordering, especially for fixtures on elevated-voltage circuits.
Wattage: Confirm the fixture is rated for 100W.
Beam Spread: Confirm 25° flood is appropriate for your application.
Base Type: Confirm fixture socket accepts a standard E26 medium screw base (standard for PAR38 lamps; not explicitly stated in source).
Physical Fit: Confirm 5.31" MOL and 4.75" diameter fit within your fixture's lamp housing.

Safety and Handling Guidelines

Do not touch the quartz capsule with bare hands. Skin oils cause hot spots leading to premature failure. Use clean gloves or a lint-free cloth.
Extreme Heat Warning: PAR38 halogen lamps operate at high temperatures. Use only in fixtures rated for this wattage and lamp type.
Allow Cooling: Allow the lamp to cool fully before handling or replacement.
Outdoor Use: If used outdoors, confirm the fixture is rated for outdoor/wet location use.
