OSRAM 93638 EKE MR16 150 W 21 V GX5.3 - Halogen lamp with dichroic reflector for projection and fiber optics

The OSRAM 93638 EKE is a 150W , 21V MR16 halogen lamp with a GX5.3 base, designed for special lighting fixtures, microscopy , fiber optic illumination , and medical-scientific equipment. Its dichroic reflector optimizes heat management by deflecting some of the infrared radiation backward, resulting in a clean light beam over the work area. It offers a 44.5mm focal length (for precise alignment in optical systems), a 200-hour nominal lifespan, and a CRI of 100 with a nominal color temperature of 3300K (professional tungsten), maintaining natural and stable color rendering in demanding applications.

The MR16 geometry (Ø 51.0 mm) and overall length of 44.8 mm facilitate integration into compact printheads. The s90 burn positioning and recommended forced cooling ensure reliable and consistent operation. Standard identification: ANSI EKE .

Frequently Asked Questions

Is it compatible with 3200 K? Many devices refer to “3200 K” as the tungsten standard; the official OSRAM datasheet specifies a nominal 3300 K.

Can it be regulated? Yes, with transformers/regulators suitable for 21V halogen lamps and respecting forced ventilation.

What installation precautions are required? Align the lamp to the optical axis, avoid touching the glass with your hands, and ensure adequate cooling of the housing.
