I have two lighting switches in the kitchen. One switches Three 240v halogen bulbs, the other six screw-in reflector or standard screw-in bulbs. None of the bulbs last for long. I thought that the halogen would last for a long time, but they don't, this usually results in the 5 amp lighting fuse blowing. Any answers Please?

The fuse will blow to protect the cable/circuit. this could be because of the fault on the lamp blowing (resulting in a fairly short surge of current) or because you are overloading the circuit(you have too much on it?)
add up the watts (that you are likely to have on at the same time)on the circuit, this should be less than 5A x 230V = 1150 Watts.
three 240 halogen bulbs? are these GU10 50W?(circular and conical in shape with a cylinder at the base? or are these outside lights 500W Halogen ?
Standard screw in reflectors R80?? what wattage??
could be due to loose connections any where back to your fuse board.
could be due to fluctuations in the incoming electrical supply.
could be due to faulty switch?
could be due to a faulty lamp holder (check for signs of heat an corrosion.
perhaps put a dimmer switch on the circuit, by reducing power to the lamp you can improve life.
many more ideas just ask.

The more lights you have on any one line causes more heat due to more current flowing thru it.If you have more than 1 or 2 lights on a line it will cause a draw on your breaker or fuse.Fuses are not the way to go with electricity.Breakers are more reliable and handle the load better.Having that much request for electricity at one time may be causing a lose of the correct amount of current in other parts of the house.You may trying to reduce the the size of your bulbs and or convert the bulbs to condescend.Gas bulbs are more reliable and cost efficient.

Not likely a short as this is not usually going to blow the bulb First I would check that you have the correct voltage bulb. I know that it sounds crazy but stranger things have happened and then if that is OK check the rate at which the bike is charging. If the charging voltage is just about 1 to 2 volts above battery voltage that is about OK but if it goes above say 3 or more above battery then the highest wattage bulbs will be the first to go Good luck

If the fitting for the light bulbs is such that just the last 1/2" or so of the bulb is showing then your bulbs will have a short lifespan due to excess heating.

Ah, a query of modern times - when there was no light at all - burning flames - all they wanted was the electric bulb - now we complain about them left and right.
Well, they are mass produced. They are not meant to last a long period of time, and it is a design flaw - don't blame the messenger.
Any spect of moisture, food, grease or foreign matter on the surface of the bulb is going to decrease its lifetime (as in a Kitchen, this is very likely).
Switch to florescents if you are really unhappy with the incondescent bulb - it has serious flaws, limited lifespan, and is very fragile.

Some cheap halogens have a short life. Try Phillips - they tend to last a long time though can be pricey.
Maybe it's just bad luck. I had a spate of bulbs go followed by a long time of no failures.

Check with Edison, he invented the light bulb. hehe
Buy Philips Light Bulb!

Check the breaker. Make sure that it is working properly. (You may need to have an electrician check this). It would appear by your description that the power to the bulbs is fluctuating or too high, thus blowing the bulbs too soon.
If the fuse is working properly, try a higher fuse rating.

It could be bad circuitry. You'll need an electrician to check it out. But before you do that just check to see on the instructions what amperage the Halogen bulbs are. If they are more than 5 Amps then you need higher amperage fuses. That's about it really.

halogen bulbs are much more reliable at a low voltage, see if you can convert your lamp to 12v with a transformer.
the screw in reflector bulbs may be overheating, do they have any ventilation? try a lower wattage.
