Share 'bulb mix up?'

So I ordered through 1000bulbs last week and waited anxiously to replace my Giant Bulb, upon receiving the bulb I noticed an issue, these bulbs are 100 watt R20 bulbs, but they are 125 volt, not 120. I wondered if they might run too hot, however they also are slightly shorter than the previous bulb (maybe a cm or two) they are apparently for pool and spa use, but are still frosted, can I use them…
