Here is the product description on Cabelas page. I also attached the link to the webpage for your review. To answer your question, though, it appears they will work for you.

The Lumenok X lights up instantly with shot inertia, and stays lit, so you can track your arrow to your target and find it easily after dark. It glows for up to 40 hours until switched off, and it only adds 22 grains to the weight of your arrow. It replaces the nock of the ST Axis, ST Axis Obsession, Black Max MFX, and MAX-4 MFX.
Available: Single pack, Three pack.
