Change a Lightbulb, Save Electricity and Money!

The hall bulbs in my apartment (which I maintain) are old incandescent, and as they die I replace them with CFL bulbs to save power - a big difference since they're on 24/7.

You'll Need:
Safety Glasses
Something sturdy to stand on
Backup light - to see what you're doing.
Replacement bulb - match the original in 'wattage' to get similar lighting results.

Suggestions:
Turn off the power first. I can't access the switch/breaker for this bulb since it's locked in the boiler room.

Notes:
I had to recalibrate my camera for the new light bulbs so they looked their natural colour - warm white - hence why the light changes colour from start to finish!

It's really that easy! (No, REALLY, it is!)
