Frequently asked

Which part numbers are listed for the same lamp as the Theimer TRS 5027?

In published replacement-lamp catalogues the same lamp (same overall length and spectrum) is listed under 13 part numbers: Theimer TRS 5027, Theimer 822597, Theimer THS 5027, Heraeus 45006075, Heraeus RQ 6136 Z4 KC, Heraeus 45002214, Amba AM 617 X/S, BLV 25560441, Heraeus RQ 6139 Z4 KC, Starna 50207 S, Ushio 5000129, Sylvania MO 69.2, Kuehnast 5020-7S. Confirm the length, base and doping of the lamp in your unit before ordering.

Can you supply a replacement for the Theimer TRS 5027?

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.
