Yes, you can put a 100W metal halide bulb in a 150W metal halide fixture, as long as the fixture is compatible with the bulb's base type and voltage requirements. However, the bulb will operate at a lower output than the fixture's maximum rating, which may affect performance and light quality. Always check the manufacturer's specifications to ensure safe and proper usage.
Christmas bulbs usually last for a very long time. Especially LED bulbs. The LED bulbs usually last around 75,000 hours. But conventional Christmas lights will only last 1,000 to 2,000 hours.
Amaryllis bulbs can last for several years before they need to be replaced.
It depends on the design of the bulb. Typical incandescent bulbs last between 750 and 1000 hours of operation.
Iron filaments are not used in light bulbs because they have a relatively high melting point and poor conductivity compared to tungsten, the metal commonly used in filament bulbs. Iron would not produce as much light or last as long as tungsten in a filament bulb.
Garlic bulbs can last for about 3 to 5 months before they go bad, depending on how they are stored.
Tulip bulbs typically last about 2 to 3 years in the ground before needing to be replanted.
Lily bulbs can last for several years before needing to be replaced, typically around 3 to 5 years.
Many of Edison's first bulbs lasted less than 40 hours.
Hydrogen gas plus metal halide (depends in the anion in the acid). It's going to be a single replacement reaction, so long as it's a strong acid.
there are a few types of flourescent lights, also leds, high pressure sodiums, and metal halides. flourescents are the best bang for your buck as they are cheaper and more energy efficient. high pressure sodiums and metal halides put out more lumens per wattage, but also use more energy and put out more heat. led lights are fairly new as grow lights, and all i know about them is that they last a really long time. it also depends on what your growing and how much.
Fluorescent bulbs typically last around 10,000 to 15,000 hours. Factors that can affect their lifespan include frequency of use, temperature fluctuations, and the quality of the bulb.
