Why are light bulbs way more bright than flashlights?
In: 1
theyre not.
but for those that are, flashlights are designed to use less power because they have their power source with them. and long-lasting lightweight power is valued over maximizing brightness.
new technology has changed this a bit. more lumens (brightness) per watt (power) with newer technology.
my nightcore headlamp is rated at 190 lumens for 17hr (more like 2-3 hr sadly) on 1800mah*3.7v? = 6watt-hours. your average household bulb is 1000-1600lumens and you can expect 70-100lumens/watt from LEDs. so figure 10-15watts to run such a bulb.
you can get a flashlight that will pump out 1000 lumens or more. it just will need a 10-20wh battery to run for an hour.
