How many times a day does a digital clock display digits whose sum total equals the number of led's used to display them?
A 24 hour clock displays digits whose sum total equals the number of led's used to display them 94 times a day. A 12 hour clock displays them 108 times a day.

Why do you use ignitor for HID Lamps?
HID or high intensity DISCHARGE lamps are lamps without filaments. They work as a gas discharge system which means that they work similar to a flourescent tube, in that they have a ballast system which provides a start-up voltage and then settles down to a running voltage once the lamp is ignited.. The lamp itself usually consists of a quartz shell, filled with some type of gas such as argon, zenon, etc. As a result, they are capable of putting out some serious lumens. The big drawback is that they usually don't last as long as regular incandescent lamps or LED's, and are more expensive to replace.
How many watts of led equals 40 watts of fluorescent?
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
How many lumens is 3w LED?
it depends, lumens measures light and watts measure power. check out this article; http://wiki.renderplus.com/?title=Lumens_vs_Watts
How bright is 950 lumens?
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
How do the types of light bulbs compare?
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
How many lumens does a laser produce?
The brightness of a laser is typically measured in milliwatts (mW) rather than lumens, as lumens are used to measure the total light output of a light source such as a bulb or LED. The brightness of a laser is usually described in terms of its power output in milliwatts.
What is the LED equivalent of a 35 Watt halogen bulb?
An LED bulb equivalent to a 35 Watt halogen bulb would typically be around 4-6 Watts. LED bulbs are much more energy-efficient than halogen bulbs, so they require less power to produce a similar level of brightness.
How many lumens does a flashlight with a 1 watt LED have?
A 1 watt LED flashlight typically produces around 60-100 lumens, depending on the efficiency of the LED and the quality of the optics.
How bright is an led bulb marked 100 lumen?
Brightness is measured in lumens so the bulb has a brightness of 100 lumens. The electrical power the bulb uses is measured in watts. The efficiency of a bulb is expressed in the number of lumens produced per watt of electric power.
How many lumens in led strip lights?
About 80 lumens per watt of electric power is normal for LEDs.
How many lumens does a good projector have?
A good projector will have 2000 or more lumens, but an LED projector will have much less.
How many watts on led strip lights?
LED strip lights typically range from 4.8 to 7.2 watts per foot, so the total wattage will depend on the length of the strip you are using. It is important to check the specifications of the specific LED strip light you are using to determine the exact wattage.
Need to know the equivalent of watts against lumens?
The conversion between watts and lumens depends on the type of light source. For incandescent bulbs, a 60-watt bulb typically produces around 800 lumens, while a 100-watt bulb produces around 1600 lumens. However, with LED bulbs, a 10-watt LED bulb can also produce 800 lumens, showing that lumens per watt can vary depending on the technology.
