Incandescent bulbs:
Advantages:
-Cheap bulb prices
-Most commonly used, so more options
Disadvantages:
-Most energy is wasted by heat
-Expensive running cost
-Short bulb life length
-High wattage
Light-emitting Diodes:
Advantages:
-Very cheap running cost
-Very long bulb life length
-Produces a good light
-Low wattage
-Does not waste energy from heat
-Eco-friendly use of materials
Disadvantages:
-Cannot produce as much light when compared to conventional types
-Initial installation and bulb replacement more expensive
-Not very common, so less options
-Bulb type cannot replace an incandescent bulb
Compact Fluorescents:
Advantages:
-Low wattage
-Fairly low bulb price
-Low running cost
-Compatible with most fixtures
-Long life life
Disadvantages:
-Method of producing light can be harmful
-Harmful greenhouse gasses are used

Hey Mike,
I was checking out solar and led lighting combinations for my report and came on this link that combines the two in case you want to take it to the next level.
"Solution to enhance the acceptability of solar-powered LED lighting technology",
Renewable and Sustainable Energy Reviews, Volume 14, Issue 3, April 2010, Pages 1096-1103

Cheers,
Tony.
I was wondering when you can start to see the cost vs initial start up even out?
Thanks Tony,
I was actually wondering if the use of solar power would even be beneficial since LED's have such low energy requirements.
I haven't started any calculations yet graham, but for an entire house my guess would be around 5 years. I'll let you know when i get there.
