    Why Conversion Matters

    When you switch from traditional bulbs to LEDs, you want to keep your rooms bright and comfortable. LED Watt Conversion helps you choose the right bulb for your needs. You might notice that LED bulbs use much less energy than incandescent bulbs. This does not mean they are dimmer. LEDs produce more light with less power.

    Manufacturers use lumens to measure brightness. In the past, people used wattage to guess how bright a bulb would be. This method does not work well with LEDs. LEDs can produce 70-100 lumens per watt. Incandescent bulbs need much more power to reach the same brightness. You can see the difference in the table below:

    You save energy and money when you use LED Watt Conversion to pick your bulbs. For example, a 60-watt incandescent bulb can be replaced by a 7-9 watt LED bulb. You get the same brightness but use much less electricity.

    Common Myths

    Some people think that wattage shows how bright a bulb is. This is not true. Wattage only tells you how much energy the bulb uses. Brightness comes from lumens. You should look for lumens when you buy new bulbs.

    You might hear that all LED bulbs are the same. This is not correct. The quality of the bulb affects how well it works. Some LEDs last longer and shine brighter than others. Color temperature also matters. Bulbs with a higher Kelvin rating look cooler and whiter. Bulbs with a lower Kelvin rating look warmer and more yellow. These factors change how you see the light in your room.

    Tip: Always check the lumens and color temperature on the package before you buy an LED bulb. This helps you match the light to your space.

    Manufacturers use LED Watt Conversion to help you find the right bulb. They focus on lumens, not wattage. LEDs give you more light for less energy. The efficiency ratio is about 7:1. This means a 10-watt LED can replace a 70-watt incandescent bulb.

    You also save money every month. The table below shows how much you can save:

    When you use LED Watt Conversion, you make smart choices. You get the right brightness, save energy, and spend less money. You also help the environment by using less electricity.

    Lumens vs. Watts

    What Are Lumens?

    You may see the word "lumens" on every light bulb package today. Lumens measure the total amount of visible light a bulb gives off. This unit helps you compare brightness across different types of bulbs. A lumen shows how much light you get from a source, not how much energy it uses. For example, a 100-watt incandescent bulb produces about 1600 lumens. If you want a bright room, you need a bulb with a higher lumen count.

    Lumens provide a clear way to choose the right bulb for your space. The higher the lumens, the brighter the light. This measurement is important for tasks that need strong lighting, like reading or cooking. You can use lumens to match the brightness you want, no matter which technology you choose.

    Note: Lumens focus on the light output, while watts only show energy use. Always check lumens first when you shop for bulbs.

    Lumens for LED Selection

    When you pick an LED bulb, look for the lumens listed on the package. This number tells you how bright the bulb will be. You can use LED Watt Conversion to help match the brightness of your old bulbs. Most packages also show the equivalent wattage for incandescent bulbs, making it easier to choose.

    Here is a simple table to help you compare:
