Light energy W= qV=hf , then light frequency or color depends on energy qV here V is volts.
Thus, f = qV/h = (240Thz/volt) V indicating infrared frequency/volt.
If a light bulb is rated at 60 Watts, the voltage will depend on the specific type of bulb. For a typical incandescent bulb, the voltage would be around 120 volts. However, for an LED or CFL bulb, the voltage could be different, such as 120 volts or 240 volts.
The color of your poi may depend on the type of fabric or material used, the lighting conditions, and the color of the LED light inside. Try changing the LED light color or using a different fabric to achieve a purple color.
LED light does not separate into colors after passing through a prism because LED light is typically composed of a single color or narrow range of wavelengths. Unlike white light, which contains a broad spectrum of colors that can be split by a prism, the emission spectrum of LED light is limited, resulting in no observable separation.
The LED light spectrum is important in determining the quality of light emitted by LED lights because it affects the color rendering, brightness, and energy efficiency of the light. Different LED light spectrums can produce different colors of light, affect how well colors appear under the light, and impact the overall visual experience. By understanding and controlling the LED light spectrum, manufacturers can create LED lights that meet specific lighting needs and preferences.
It depends on the color of the led you have. Normally it changes between 1.5 V and 2.5 V. But if you need to use white or purple leds those leds need more power like 4-5Volts. Im gonna calculate for a standart red led, a red led needs 20 mA and 2 volts to light up. So we know the formula that we can calculate how many watts does the led need, P = U * I P = 2 * 0.02 = 0.04 W. I used the average values. I hope I didnt make any mistake :)

A normal incandescent or fluorescent lamps can not change colors. Even an LED can not change color. But an LED can be designed to have a certain color. Color changing LED is actually a combination of of three LEDs encapsulated in one casing. By turning the LED on or off a combination of colors can be achieved.
That depends on the current. The formula P=IV (where P is power in watts, I is current in amps and V is voltage in volts) is how you calculate the power. So if the current is 2 and the voltage is 3 then P=2x3=6Watts. Use an ammeter to determine the current.
The color of LED light most effective in promoting sleepiness is red.
To control a LED light with a remote, you can use a remote-controlled LED light kit. This kit typically includes a remote control and a receiver that connects to the LED light. By pressing buttons on the remote, you can turn the LED light on or off, adjust its brightness, and sometimes change its color. Simply follow the instructions provided with the kit to set it up and start using the remote to control the LED light.

A: The voltage for LEDS varies from 1.8v to even 5 volts. These voltages also varies from color to color. A 5 volt LED usually has a tiny resistor in series so the led can be tied across a 5v buss as a unit. Some manufactures actually has two LEDS in series to provide more brightness
It depends on the wattage and how much light the LED emits. 3000K refers to the color temperature of the light and has no relationship to brightness.
The most calming LED light color for relaxation and stress relief is blue. Blue light has been shown to promote relaxation and reduce stress levels.
You can control a remote LED light from a distance by using a wireless technology like Wi-Fi or Bluetooth. Connect the LED light to a smart device or a remote control that communicates with the light through the wireless technology. This allows you to turn the light on or off, adjust its brightness, and even change its color from a distance using the smart device or remote control.
A: LED NEEDS at least 1.8v to light and a current of at least 10ma. Try 2 AAA battery in series and a 70 resistor if it doesn't light it means the voltage must be greater the 1.8v it could 5v volts.
