Satco item S1940 · UPC 045923019401
This is Satco S1940, a ET18 / ET23-1/2 lamp on a Mogul screw (E39) base. If you are replacing a bulb, the Satco number on the old sleeve or the fixture label is the surest way to match it — order by S1940 and you get the same lamp.
ET-shape high-pressure sodium lamps: what ET18 / ET23-1/2 means
Tubular high-pressure sodium lamps with a mogul screw base, recognisable by their amber output. Match the wattage and the ANSI ballast code stamped on the fixture; HPS lamps are not interchangeable with metal halide without changing the ballast.

Buying more than one
Most Satco lamps are stocked in multiples and many are sold by the case. Bulbs in a shared fixture age together, so relamping the whole fixture at once keeps colour and brightness matched and saves a second trip up the ladder.
