3057K - Design AMPS: 2.1, Rated Life: 2,000 4057K - Design AMPS:2.23, Rated Life: 4,000
The kx bulb has an extra pair of wire contacts (4 instead of 2) per side. This decreases the amount of current each contact has to handle and decreases the amount of heat build up on the socket. The regular 3057 or 3057K bulb can be used, but it will probably burn out a bit faster and can damage the socket over time.
The "K" in 4057K bulb stands for Kelvin, which is a unit of measure for color temperature. It indicates the color appearance of the light emitted by the bulb, with higher Kelvin values corresponding to cooler (bluish-white) light and lower Kelvin values corresponding to warmer (yellowish-white) light.
Yes, one is just a little bright than the other. Done it no problem.
You can unscrew a light bulb.
it is difference between wet bulb temperature and dry bulb temperature.
Sylvania 4057k Some stores will have them listed as 4057LL... but it's the same I've seen the Sylvania 3157LL bulb work as well. Here's a visual step-by-step of the process:
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
The difference between wet-bulb and dry-bulb temperature is called the Wet-Bulb Depression. It is a measure of air humidity, with a larger depression indicating higher humidity levels.
To calculate the difference between a dry bulb and a wet bulb temperature, you measure both temperatures using a thermometer. The dry bulb temperature is the ambient air temperature, while the wet bulb temperature is measured with a thermometer that has its bulb moistened with water. The difference between these two temperatures indicates the level of humidity in the air; a larger difference suggests lower humidity, while a smaller difference indicates higher humidity. This calculation is often used in meteorology and HVAC applications.
