    spectrum, they look more like the incandescents they are replacing and in my opinion, they are easier to read with.  You do, however need to be careful if you are using a dimmer circuit.  Make sure the LED's packaging says "Dimmable" because some dimmers can cause premature destruction of the LED's power supply or flickering light.  You should ask the manufacturer or lighting sales person who is truly knowledgable about the kind of dimmer that should be used.  LED lights generally perfer full voltage and some manufacturers recommend Pulse Width Modulation (PWM) dimmer circuits, with the advantage that they always come on at full voltage, but the switching action is so fast, it does not result in flicker, and it preserves the full life rating of the bulbs.

    I have transitioned about half of my lights to LED and have never liked or much used compact flourescents because I didn't want to use mercury with its recycling requirements, their poor (for me) life performance, their hard starting when installed in a cold place and poor light quality.  In my view, LED's are far superior for cost, life and reduced maintenance.  Their ability to run cold, a real plus for Christmas tree lights is also a benefit I like.
