Are you in the market for a reliable light-dependent resistor? Look no further than the exciting new GL4516 LDR! This powerful light-dependent resistor is ideal for any hobbyist looking to build out a unique lighting project. With its high-end specs, including a max voltage of 150VDC and maximum power dissipation of 50mW, you can create the bright and vibrant lighting displays of your dreams! 

LDRs (light-dependent resistors) are used to detect light levels, eg in automatic security lights. Their resistance decreases as the light intensity increases. In the dark and at low light levels, the resistance of an LDR is high, and little current can flow through it.

Photoresistors also referred to as light-dependent resistors (LDR), are light-sensitive devices most commonly used to indicate the presence or lack of light or measure the intensity of light. In the dark, their resistance is very high, sometimes upwards, but when the LDR sensor is exposed to light, the resistance drops dramatically depending on the light intensity, even on some ohms. LDRs have a sensitivity that varies with the wavelength of the light applied and are non-linear devices.

LDRs are very sensitive to changes in light intensity. This means that they can detect even small changes in the amount of light that is present. This makes them ideal for use in applications where precise light sensing is required, such as in automatic lighting systems or in photography equipment. 

Another advantage of LDRs is that they are highly reliable. They are designed to be durable and to operate reliably over long periods of time. This means that they can be used in applications where continuous operation is required, such as in outdoor lighting systems or in security systems.

Which resistor to use with LDR?
 
To get it to work optimally the LDR value and resistor value are chosen to balance current draw, ADC input impedance, and light response. Easy answer is pick a resistor that's equal or less than the LDR and you'll get a usable output. For example, for a 10K LDR use a 1K to 10K resistor.
