What is a type s lightbulb?

Question

I have a small desk lamp that needs a light bulb, and it says that it needs a "40 Watt Type S or Smaller". I've looked everywhere and all I can find is type A. Can I just use type A, or where would I find a type S?

Answer 1

Incandescent light bulbs come in a range of shapes and sizes.  The letters represent the shape of the bulb. The names (letters)  of the shapes may be slightly different in some regions.

General (A), Mushroom

Pear-shaped (PS)

Spot types (SP)

Globe(G)

Etc

If the bulb looks the same and it fits - use it.

[How to read bulb shape codes. The letter designations for each incandescent bulb category indicate the industry code for bulb shape. For example a "BR" bulb indicates a "bulged reflector" shape. The number after the shape code indicates the maximum bulb width in 1/8". A "BR30" bulb has a maximum width of 30 x 1/8" or 3.75". ]

Answer 3

Type 'S' refers to bulb size.

An old Phillips lampm catalogue lists several 'S' lamps at different voltages with different wattages and base types.

Take the old lamp to an electrical supply house.

If type A of less than 40 W. will fit the socket, you're probably ok.

Answer 4

Maybe S stands for SMALL, which means, smaller bulbs than the ones usually used for chandeliers etc. Use type A, why not, I believe it won't do harm :S
