Frequently asked

Which part numbers are listed for the same lamp as the Theimer TR 5047?

In published replacement-lamp catalogues the same lamp (same overall length and spectrum) is listed under 10 part numbers: Theimer TR 5047, Theimer TH 5047, RST 1011219, Colight 1530, Heraeus 45006063, Heraeus Q 2133 Z4, Colight 3007100, Heraeus 56066463, Heraeus Q 2131 Z4, Kuehnast JGMH 2210-7. Confirm the length, base and doping of the lamp in your unit before ordering.

Can you supply a replacement for the Theimer TR 5047?

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. Lamps supplied by Kilowatt Lamps are compatible replacements and are not made by or affiliated with the brands named.
