SKU
2240
Note: All model 2240 eyepieces manufactured after January 2008 employ the model 509 as the light source. If you wish to upgrade an older version of the 2240 to accept the 509, you may do so by purchasing adapter number 15307. Replace the bulb housing on the older models with this adapter, and you'll be set to use the 509. Otherwise, the replacement bulb for 2240 eyepieces made before 2008 is the L3311-1 (GE157).
