Millikan LED Light Source

Introduction

The AP-8212 Millikan LED Light Source is designed for use with the AP-8210 Millikan Oil Drop Apparatus.

You can use the AP-8212 Millikan LED (light emitting diode) Light Source to replace the Light Source Assem-

bly on the AP-8210. The Millikan LED Light Source is brighter than the original light source on the AP-8210,

and the brightness of the LED Light Source is adjustable. The very long expected life span of the LED means

that the LED Light Source should never need replacement. (NOTE: If the LED does fail, do not attempt to

replace it. Contact PASCO about returning it for repair.)

The Millikan LED Light Source includes the LED assembly and four screws for attaching the LED assembly to

the base of the AP-8210 Millikan Oil Drop Apparatus. The Millikan LED Light Source uses the same power sup-

ply (100 to 240 VAC, 10 VDC, 1 A) as the Light Source Assembly that it replaces. The LED brightness adjust-

ment knob is on the top of the LED Light Source. Turn the knob clockwise to increase brightness and

counterclockwise to decrease brightness. Note that when the LED brightness knob is turned fully counterclock-

wise, the LED may be completely dimmed or it may still be slightly illuminated.
