Standard Relay vs SSR vs TRIAC for Switching CFLs
10 cycles per day isn't much. Simple math says 100000 / 10 / 365 gives a life of 27 years for your EMR. Even if we take the 100K as a mean and assume failure can occur at 50%, you're still over your 10 years.

If it were me, I'd just go with the mechanical relay.
