Philips 410337 (13289) EKE 150W 21V GX5.3 Halogen MR16 Projection Lamp - ANSI EKE, 3250K, 900 Lumens

The Philips 410337 (Type 13289 / EKE) is a high-intensity 150W 21V halogen MR16 projection lamp designed for professional optical, medical, scientific, and projection systems. Featuring a GX5.3 bi-pin base, precise C-6 filament alignment, and quartz-UV open-face construction, it delivers full-spectrum light with a CRI of 100 and 3250K color temperature for exceptional color accuracy comparable to natural daylight. This Focusline series lamp offers consistent lumen output, distortion-free performance, and reliable operation in demanding applications such as slide projectors, microscopes, fiber optics, endoscopes, and surgical lighting. Note: While the title lists 50W 13.8V, the detailed specs confirm this is the standard Philips EKE 150W 21V model (common cross-reference confusion in listings).

Safety & Compliance Information

Caution

• Risk of Burn: Allow lamp and fixture to cool completely before handling; turn power off before installation/removal.
• Risk of Shattering: Dispose of in a closed container; do not use if outer envelope is scratched, cracked, or broken.

Warning

• Risk of Electric Shock: Disconnect power before inspection, installation, or replacement.
• Risk of Fire: Keep away from combustible materials; use only in fixtures rated for this lamp.
• Pressurized Lamp: Unexpected rupture may cause injury, fire, or property damage; avoid direct contact with water, liquids, or metal; do not exceed 110% of rated voltage.

High-performance halogen projection lamp for critical optical, medical, and scientific applications—offers unmatched color fidelity and intensity. Due to short life and high heat, consider modern LED MR16/GX5.3 equivalents (150W-class) for 10,000+ hour life, cooler operation, lower energy use, and similar or better color performance in compatible systems.
