If you dont mind splodey light bulb.
Technically speaking a bulb and a lamp are the same thing. You can use a 60 watt bulb in a fixture calling for a 40 watt bulb but I wouldn't. The lighting fixture may get to hot, melt and start a fire.
Yes, you can use a 10 watt 12 volt bulb instead of a 5 watt bulb as long as the fixture can handle the higher wattage. Just be aware that the 10 watt bulb will be brighter and may generate more heat, so ensure there is proper ventilation and that the fixture can handle the increased power load.
you can always less less wattage. for safety, never use more wattage recommended due to fire hazard.
No, it is not recommended to run a 50 watt halide bulb on a 100 watt halide ballast. The ballast should match the wattage of the bulb to ensure proper operation and to avoid potential damage to the bulb and ballast. It is best to use a ballast that is rated for the wattage of the bulb being used.
What may happen is the 7W bulb may burn out quickly because of the dryer heat. I suppose worse case might be an exploding 7W bulb that would ignite lint and cause a dryer fire. You should always use what is recommended by the manufacturer.
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
A 75 bulb will use more electricity.
Yes.
It is not recommended to use a 67 watt bulb in place of a 60 watt bulb as the higher wattage could potentially cause overheating issues. It is best to stick with the recommended wattage for the fixture to ensure safety and proper functionality.
No, you can not use a 150 watt high pressure sodium bulb with a 70 watt ballast.
The highest watt headlight bulb you can use in a 2000 Mazda 323 is 65 watts. Most vehicles use a 55 watt bulb.
Usually the 60-watt limit is used to prevent the lampshade overheating, so a 75-watt bulb should not be used. But if more brightness is required, try a low-energy bulb because a 15-watt one gives the same light as a 75-watt incandescent (old-style) bulb. Or a 20-watt would be even brighter.
