Frequently asked

Which part numbers are listed for the same lamp as the Ushio MHL 17?

In published replacement-lamp catalogues the same lamp (same overall length and spectrum) is listed under 9 part numbers: Ushio MHL 17, Beltron 28052, Kuehnast JGMHO 2200-0, Sylvania M036, Theimer TH 2510, Amba AM572X, Heraeus Q 2123 Z11, Philips HPM 17, Dr. Fischer HPM 17. Confirm the length, base and doping of the lamp in your unit before ordering.

Can you supply a replacement for the Ushio MHL 17?

Yes — send the part number on your old lamp, a photo of its label and ends, and your exposure unit model. We check overall length, base, doping and power against the original before we quote, and quote within 24 hours.

Why does the doping matter?

The metal added to the mercury fill (iron, gallium or none) sets which UV and violet wavelengths the lamp emits. Your dry film, solder mask, screen emulsion or printing plate is sensitised to particular wavelengths, so the replacement should carry the same doping as the original.

Safety: metal-halide exposure lamps contain mercury and emit strong UV. Never run one outside its housing, wear UV-blocking eye protection when servicing, handle with gloves, and return used lamps for mercury recycling.
