Frequently asked

Which part numbers are listed for the same lamp as the Ushio MHL-6027S?

In published replacement-lamp catalogues the same lamp (same overall length and spectrum) is listed under 9 part numbers: Ushio MHL-6027S, Ushio 5000132, Theimer TRS 6027, Theimer 822697, Beltron 28062, Cure UV 191173, Kuehnast 6020-7-S, Amba AM 559 XS, Theimer THS 6027. Confirm the length, base and doping of the lamp in your unit before ordering.

Can you supply a replacement for the Ushio MHL-6027S?

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.

Specifications and cross-references compiled from published lamp-maker data (Ushio, Alpha-Cure) and a US replacement-lamp distributor's catalogue. Where sources differ the values are shown side by side. Data is given for identification only — verify against your unit's manual.
