Frequently asked

Which part numbers are listed for the same lamp as the Olec L1282?

In published replacement-lamp catalogues the same lamp (same overall length and spectrum) is listed under 11 part numbers: Olec L1282, Alpha Cure ACP-0878, Theimer TR 8222, Fabcon L1282, BLV MHL-282L, Ushio 5000093, Cure UV 191143, Ushio 25470641, Ushio MHL-282L, BLV 25470641, Theimer TH 8222. Confirm the length, base and doping of the lamp in your unit before ordering.

Can you supply a replacement for the Olec L1282?

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.
