"More environmentally friendly" isn't easy to assess, but you could certainly work out whether it would be cheaper for you.
For example:
Replace a 100W incandescent with a 15W LED bulb that costs £1.45. You are saving 0.085kWh for every hour that it's turned on. If you pay 20p per kWh for your electricity, the bulb will pay for itself after 85 hours use. So definitely worthwhile for a bulb you use several hours a day; not so for a rarely-used one.
