collecting peanut bulb

[martaW.W]

Hello, I'm new here so please forgive me if I make mistakes.
I?m traslating from English to Spanish a user's manual for a "Light head magnifying glass". It uses a 2.2V-0.25A collecting peanut bulb
I looked everywhere but I didn't find anything that cuol help to translate it to Spanish.
Could anyone help me, please? I thank you very much in advance!!

Bombilla/bombillo colector tipo o en forma de peanut (no me suena maní o algo por el estilo).

That was my try, wait for others to help further.
