A 3 volt grain of Wheat bulb used in making deployment charges along with Centrifuge Vials.

Remove the end of the bulb to expose the filament (careful with the glass) and pack with Black Powder to produce a simple efficent deployment charge.

This bulb is rated at 3 volts and as such produces an extremely low current deployment charge. Please test carefully without black powder first to make sure that the electronic system that you are using can detect the bulb and not blow the filament with its continuity check. (This has been known to happen in the past)

Ideal for use with the uMAD Magnetic Apogee Detector System.

Sold in packs of 20.
