Unless the brand manufacturer has its own factory, it may get bulbs from several different sources. Also, tiny unavoidable variations in the materials and components of bulbs can cause them to fail at different times, even with similar application and use.
Not every bulb is exactly the same.
No, not all light bulbs produce polarized light. The polarization of light depends on the source of light and its characteristics. LED and fluorescent light bulbs can produce polarized light, while incandescent bulbs generally do not produce polarized light.
The cost of a LED light bulb can vary depending on the brand, brightness, and design. On average, a basic LED light bulb can cost between $2 to $10. Specialty LED bulbs with advanced features may cost more.
Yes, in general, higher wattage bulbs produce more light than lower wattage bulbs. However, the brightness of the light also depends on other factors such as the type of bulb (incandescent, LED, etc.) and the design of the fixture.
It most certainly does. For one, there is the matter of aesthetics. Different shapes are used for different decorative applications. Round ("G" for globular) are often used in light fixtures in baths and dressing rooms as opposed to the most common "PS" or "pear shaped" light bulbs. Some light fixtures and portable lamps will only accept "T" (tubular) light bulbs such as picture and piano lamps. Certain shapes are determined by the electrical characteristics of the light bulb. Fluorescent light bulbs are tubular as a result although the tube may be wrapped or formed into different overall shapes, it is still a tube. Compact fluorescent light bulbs are simply fluorescent tubes that have been folded or wrapped into a compact shape. Light bulbs using reflectors have to be of a certain shape in order to properly reflect light in a certain direction and pattern.
Not every bulb is exactly the same.
The best UV light bulbs are made by Sylvania and Philips. The downside of the story is that UV light bulbs of those brands are among the most expensive on the market.
There are many different places one might go to purchase car light bulbs. In addition to an official brand website, one might also try the local car dealership.
Incandescent light bulbs work by passing electricity through a filament, which heats up and produces light. They are different from other types of light bulbs because they rely on this heating process to produce light, whereas other types, like LED or fluorescent bulbs, use different mechanisms to generate light.
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
No one needs to be smart as this!
The different shapes of light bulbs available in the market include A-shape, globe, candle, reflector, and tube.
Dimmable light bulbs allow you to adjust the brightness of the light they emit, giving you control over the ambiance in a room. They differ from regular light bulbs in that they can be adjusted to different levels of brightness, whereas regular light bulbs have a fixed brightness level.
The difference between the two bulbs is that energy saving bulbs have murcuary in them which lowers the amount of electricity they require and consume.
There are a huge variety of different bulbs powers offered at Light Bulbs Direct. They have lightbulbs designed for nearly every kind of wattage desirable.
The different sizes available for recessed light bulbs are typically 4 inches, 5 inches, and 6 inches in diameter.
Fluorescent light bulbs are available in various sizes, including T5, T8, and T12.
