Led A Battery Drain?

[VapinCT]

What is the purpose of the LED? I'd much rather just have a light that blinked when the battery was low. How much of a drain is the LED on the battery?

I asked this question too and was told that the LED usage would make no (or very very little) difference if it wasn't there. I asked because the Spade has the option to put the battery in backwards so the LED's won't light. I believe it was Chris who told me this.

The drain of a LED is so much less than the atomizer that it really doesn't matter at all. I'd have to sit down and do the math but my guess is the LED maybe takes away one drag of power for duration of an entire charge. Not sure that was very clear, but seriously LEDs take very little power to operate, the heating element in the atomizer draws much, much more power.

Makes total sense and that is what I was wondering.

The purpose of the LED is 1. To look cool 2. Mostly, to let you know the unit is working.

It also helps us trouble shoot issue should they arrive. Removing the LED will not help the battery life especially because there is only one. It takes VERY little power to operate

I have an LED light bulb that I use as my desk light. Inside it there are 20 LEDs. The light bulb uses only 1.5 watts but puts out the light close to a 40 watt incandescent light bulb and puts off no heat. If you want an energy efficient light bulb then a LED is the way to go. I wouldn't even worry about how much energy is being drained in an e-cig's LED. Also, The Spade doesn't have as many LEDs as it does light holes. I can't really tell how many are in there but I'm guessing one. If we assume it is using the same energy as one of the LEDs in my desk light then it is using .075 watts. 1.5 watts/ 20 LEDs = .075 watts. Doesn't sound like much to me and it is probably less than that.

Hi Schizophretard,

You guessed it perfectly!

The LED draws (20 ma) so 3.7 volts X 0.02 = 0.074 watts

The Spade (510 atomizer) draws about 1.1 amps @ 3.7 volts with a fresh battery when you turn it on.

So a LED uses less than 2% of the power available

I hope this helped

I have a maglite that uses 2 AA batteries that will make 3volts. It has a 3 watt LED. It's super bright. I used it one morning during work and I forgot it on and put it in it's holster. When I got home 8 hrs later, It was still going strong and I used it for another 2 weeks.

I thought this might give you an example of how much juice LEDs use or don't use.
