LED Bulbis currently proving to be very popular because of their very long lifespan and durability. The popular colors available for LED bulb are “warm white” or “soft white “and” bright white.” Warm white and soft white will produce a yellow hue, close to incandescent, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores.
If you want to get technical, light color (color temperature) is measured in kelvins. The lower the number, the warmer (yellower) the light. So, your typical incandescent is somewhere between 2,700 and 3,500K. If that’s the color you’re going for, look for this range while shopping for LED bulb. Eventually, the LED bulb will pay off, and in the meantime, you’ll enjoy less heat production, longer Lamp life.
Bottom line: unless you’re replacing many incandescent bulbs with LED lamps in a large house, you won’t see significant savings in your electricity bill.
