How to calculate the cost of LED lighting. Or... renting my apartment, LED lights, energy conservation and fiscal sense. Please help me!

Hi, I'd love some advice. I live in Tokyo in a rented apartment. The place comes with dimmer switches on most of the main lights in most of the rooms. Incandescent bulbs here cost about 360 yen and use 60 watts. I looked for fluorescent bulbs but none work with dimmers afaik. Panasonic is making an LED light bulb (Panasonic LDA8L-A1/D) that uses 7.6 watts, works with dimmers, puts out light equivalent to a 60 watt incandescent but costs 3300 yen. I bought one- it's very cool (both the technology as well as it's cool to the touch even when lit.)
As we all know, all of us in Tokyo and Northern Japan are in an energy-conservation mode post-March 11 quake, so there is that benefit as well (to going to LED.)
If I owned my own home, it would be simple- the cost of LEDs (even at 10X the price) benefits from almost a 10X lowering in usage of electricity.
But I rent. And there's no way I can imagine needing all of these LED dimmable bulbs at a future house.
I'm struggling with how to calculate whether I should continue to buy incandescent or start purchasing LED bulbs as the incandescent fail? My lease goes on for 2 more years.
Any advice would be appreciated!
