Replacement bulb for TD-8554A Leslie's Cube

Replacement heat source for TD-8554A or TD-8554A-220

The heat source that is used for the Leslie's Cube is a 100 W frosted incandescent light bulb.  An LED replacement bulb that is rated for the light output of a 100 W incandescent bulb will not work as the experiment requires the full 100 W power output of the bulb. 

Our part number for this replacement bulb is 526-020 if you are using the 110V version of the apparatus.  This 100 W bulb is rated for 110 V power.

If you are using the TD-8554A-220 (in countries with 220 V mains power) the replacement part number is 526-028.  This is also a 100 W incandescent bulb, but this is rated for 220V.
