The OSRAM ESX is a 20W MR16 halogen bulb engineered for precision spot lighting applications requiring a tightly controlled beam. Operating at 12V with a GX5.3 bi-pin base, this halogen lamp delivers a narrow 10-degree spot beam that concentrates light with intensity and accuracy, making it well suited for display lighting, accent lighting, retail merchandising, gallery illumination, and architectural highlighting.

Built around an axial filament construction within a dichroic reflector, this MR16 halogen bulb features a UV-filter cover glass that helps protect displayed objects and surfaces from ultraviolet radiation. The dichroic reflector directs heat rearward rather than forward, reducing the thermal load on illuminated subjects — a meaningful advantage in jewelry cases, museum displays, and retail showcases.

This halogen MR16 produces a warm 3000K color temperature with a color rendering index of 100, meaning colors appear with full natural accuracy under its light. Center beam candlepower is rated at 3000CP, delivering concentrated intensity within the 10-degree spot field. The lamp measures 1.75 inches in length and 2.00 inches in diameter, conforming to the standard MR16 form factor for compatibility with a wide range of low-voltage track, recessed, and display fixtures. Rated average life is 5000 hours. Sold individually.
