Pentair Pool Light - Halogen Bulb Question

[jpmorgan12]

I need to replace the Halogen bulb in my Pentair Aqua Lumins II pool light. Are the 120V/250W halogen bulbs at Lowes or Home Depot any different than the $25-$35 120V/250W halogen bulbs that the pool stores and pool web sites sell? At 2 for $7, I am hoping that the Lowes or HD versions are acceptable.

Thank you
