IEEE 802.3bt can deliver up to 71W at the destination: just pull Cat 5/6 everywhere.
In the commercial/industrial space this may be worth it: how long do these bulbs last? how much (per hour (equivalent)) do you pay your facilities folks? how much time does it take for employees or tenants to report an outage and for your folks to get a ladder (or scissor lift) to change the bulb?
