Can low wattage energy saving bulb safely be used in place of lamp’s max incandescent equivalent?

If max wattage on lamp is 60 can I use an energy saver light of less wattage even though that light is brighter than the incandescent 60 watt bulb? Or will the heat from the brighter energy saver he higher and create any fire hazard?

    you are safe to use the CFLs bulbs. One of the good things about them is that they don’t give heat ( as a waste byproduct ). So go ahead and use them worry free.
    I have used them for years and my power bill is always lower than my neighbors even though we have a bigger house.

    If the wattage is less then the heat is less. The CFL’s equivalent light out put is higher that an incandescent, so actually if you choose a cfl with the same wattage rating, you will get a lot higher light output. However doing this will not save any energy and will not cost less to use.
    The other answer is absolutely WRONG, cfl’s do produce heat, just not as much. It all depends on the wattage rating. 100 watts will give off 100 watts worth of heat, no matter what kind of bulbs.

    the newer bulbs put out very little heat,
    the rating on a light fixture is for a incandescent bulb that puts out a lot of heat,
    so a 60 watt bulb will put out more heat than a 40 watt will
    you can put a 100 watt fluorescent bulb in a rated 60 watt fixture and still be safe,

    If the max wattage on a lamp is 60 watts, then that is your max watts no matter if it is an incandescent or compact florescent light (CFL). The confusion takes place in the comparison. For example, if you were to replace the 60 watt incandescent bulb with a 25 watt CFL, you are using 35 less watts, and will save that much on your power bill. This will not create any fire hazard.

    I know you did not ask the following, but it helps answer your question.

    Savings = watts saved times cost of kWh

    If you are paying $0.10 (ten cents) per kilowatt-hour, and if this bulb is used 5 hours per day, then 5 hrs x 35 watts saved = 175 watt-hours saved per day

    175 watt-hours x 30 days = 5,250 watt-hours saved per month

    5,250 watt-hours / 1000 = 5.25 kilowatt-hours saved per mo.

    Savings = 5.25 x $0.10
    Savings = $0.525 per month

    The result is less cost for brighter light that lasts 10 times longer.

    The great thing about this is, the 25 watt CFL will be about as bright as the 100 watt incandescent, and are cooler to the touch as well. And again, reducing watts in a lamp will not create a fire hazard!!!
