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.
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.
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.
