"It is a little overkill but for the price per unit and the bundle, it's not a bad deal. This person might blow through a couple of them if he doesn't set up his thermal regulations and 10Amp sense circuit. He's going to be pushing alot of heat depending on if they want to be pulsing or have it continuously on. He is going to have to also consider that even though he is supplying 155VDC, needs to consider the voltage drop and accommodate for that accordingly. Did a quick spin search and found an alternative and cheaper mosfet if he wants to try which is IRF840.

I would say my top considerations with be thermal management and current spike ( which again. If not regulated will definitely blow up hahaha or at the very least they will watch the back of the mosfet literally melt)"
