LED needs comparatively less current to glow.
Answers
Answer:
The LED current must be less than the maximum permitted for your LED. For standard 5mm diameter LEDs the maximum current is usually 20mA, so 10mA or 15mA are suitable values for many circuits. The current must be in amps (A) for the calculation, to convert from mA to A divide the current in mA by 1000.

Are lights increasing your electricity bill?

Here's how to choose efficient bulbs
How often does your electricity bill shock you? Do you wonder how your bill is so high even when you don’t use high-consumption appliances much? Ever given a thought to light bulbs and fixtures? No? Well, you should, because these can form as much as 25-30% of your monthly electricity bill. Reason enough to pay close attention to the type of light bulbs you use, and whether it’s time to change them.
When you do the math, it’s difficult to calculate both the cost efficiency and energy of light bulbs. Mint Money takes a look at different types of bulbs used and their efficiency.
Here are two terms we must understand before we move any further: wattage and lumens. Wattage measures the amount of electrical power a light bulb consumes. Watt is a measure of power or energy. Lumen is a measure of brightness, i.e. the amount of light the bulb will provide. Keep both in mind when purchasing a light bulb. A higher wattage doesn’t mean higher lumens; but higher the lumens per watt, the brighter is the bulb.
