The wattage of bulb one uses in a bedroom lamp depends on several factors. If it is a lamp used for back ground lighting or a night lamp, one would use a very low wattage bulb. If it is for a bedroom reading lamp, one would want a stronger wattage. The biggest factor on deciding what wattage to use is the wattage suggested by the lamp manufacturer. All lamps are marked with recommend bulb wattage.

It depends on the size of the lava lamp

Incandesent round mini-bulb designed specifically to fit into lava lamp with appropriate wattage to heat the volume of the lamp to a temperature that melts the wax compound without overheating the liquid volume. Very precise so use only the manufacturer's recommended bulb.

You should not use a higher wattage bulb in a lamp that says 40 watts. The higher wattage could cause the lamp to catch fire due to the excess heat and could cause you serious electrical problems.

Yes, the reason for watt rating lamp fixtures is to prevent oversizing the lamp with a higher wattage bulb than the manufacturer recommends. Lower wattage bulbs are fine.

If the lamp is rated for the maximum bulb wattage, usually 150 watts, and there is a switch and base that accommodate the bulb you should be okay.

Yes, as long as the voltage is the same and the bulb has the same or less wattage. The fixture is rated at a certain wattage that can be found on a label somewhere on the fixture. Never use a larger wattage than what is stated on this label.

My Lava Lamp said to use an A 15 aplliance bulb. I went to Walmart and they didn't have them so I thought the A 19 replaced it. Worng. The A 19 does not fit. My lava lamp had a sticker iside of it saying what type of bulb to use, but, of course, I bought the wrong one. The A 19 is too tall, the bottle didn;t fit.

The light bulb that is in the lamp is what determines the wattage load. All lamps are rated for a maximum wattage and this rating should not be exceeded due to a possibly heat build up.

Check the label on the inside of the lamp shade. There it will tell you the maximum size wattage allowed for that specific fixture. If it isn't a lamp fixture but a porcelain lamp holder then yes you can.

No you can't. You can use a metal halide lamp of the exact wattage of the original mercury lamp. You cannot vary on wattage at all.

It is safe, you have to double turn the switch to make contact.

Depends on the power - the wattage of the lamp, and how long it is lit. You take the power - the wattage of the lamp, and multiply with how long it is lit. A 100 W bulb - 0.1 kW - will use 0.1 kWh in one hour. Or 1 kWh in 10 hours. Or 10 kWh in 100 hours.

If the socket threads of the lamp are the same then yes the bulbs can be interchanged. The 5 watt bulb will glow brighter than the 4 watt bulb. If by a 4 watt light you mean a 4 watt fixture, then it is not recommended to place a larger wattage lamp in a fixture that is rated by the manufacturer at a specific operating wattage

The label 60 watts bulb max is referring to each individual bulb, not the total in the light fixture.

No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all

To attach a bulb to a battery you have to use a lamp holder. Connect the lamp holder to the battery and then screw the bulb into the lamp holder.

You can use a lower wattage bulb on a higher wattage fixture provided the voltage rating is the same and the bulb base is the same.

The maximum amount of wattage that is allowed to be used in any lighting fixture is on the label of the fixture. The manufacturer is bound by rules that they have to state on each fixture what the maximum amount of watts that the fixture can take before damage is done to the fixture or any surrounding objects. The damage from a lamp is in the form of heat, the higher the wattage of a lamp results in a higher heat from the lamp. Fixtures are allowed any wattage up to that recommended nameplate label wattage.

No. You must stick with proper lamp style and wattage for that fixture

No you have to use a heat lamp which looks like the kind you use outdors but distance to bottom and wattage are critical and found in most care guides.

Obviously not. It would blow the bulb by 600W! <<>> Yes you can use a 60 watt light bulb in a lampholder that is rated a 660 watts. The rating given to these lamp holders is the maximum amount of wattage that can be applied to them safely.

If I am correct you are referring to the note on lamps that says use max 60 watt bulb. Unless you have a special lamp such as a heat lamp. You shouldn't use a higher wattage bulb than recommended as the lamp shade could melt or become to hot and possibly catch fire. Think what could happen if the lamp shade touched the bulb, incandescent bulbs emit alot of heat. Also the wiring in the lamp may only be able to supply enough voltage to power a 60 watt or below bulb. I personally recommend you just use a cfl (you know the small spiral type) instead.

Incandescent bulbs are rated by wattage. If you look on the top of the bulb it tells you the wattage it uses. If the bulb is a 50watt bulb then 50watts, if a 75watt the 75watts and so on.

The fixture recommended wattage is a maximum limit. Using a smaller wattage bulb is fine.
