Electrical wattage savings with LEDs
Well since there hasn't been much info on the subject since the 07's, I figured I'd give my information on what I know and have observed.
The only one I cam across was this: http://www.ninjette.org/forums/showthread.php?t=31087 I find it to be pretty accurate, however I have converted quite a bit of my stuff to LEDs (everything but the turn signals and head lights). I have installed an ammeter and have some input on the stock draw of our electrical system. Below is the data from the new service manual. As you can see, the 08-10 years came with a 12V 6A battery, while the 11-12 years came with the 12V 8A battery. Also the 08-09 stator puts out 19A while the 10-12 puts out 20A. This may or may not be related to the battery change. So assuming the regulator can also put that kind of power out, we have about 20 amps available to us. This is rated at 5k rpm and 14V, which gives us ~280 watts of power. When riding the bike with a charged battery, no matter if I was idling or at high rpm, the bike was drawing 5A-6A just running. This is with nothing on but the stock stuff and my aftermarket computer system, which draws about 0.5A, so the bike probably draws about 5A stock. With a turn signal on, it was more around 6A-7A. With the high beam on, it was closer to 8-9A. With a turn signal on and high beams, it is more around 9-10A. These readings are an average. When I had instant data, while idling, I got current draws as low as 2A to as high as 10A, so I had to average, but I did take a short period of time to average (3 seconds). So realistically, it seems we have a solid 10A available to use when having all LEDs except for turn signals and head lights. This may be important to know for high draw applications, such as heated clothing. So for 10A at 14V, that is 140 watts extra to use. The other post showed around 88 watts available to use with the stock bulbs. Just goes to show that by converting all the bulbs except the turn signals and head lights to LEDs can actually save you a lot of power (possibly 40+ watts). LED specs: Looking at the paper specs, each of my meter LEDs draws about 1.4W, so that is 4.2W for the three. Each indicator LED draws 0.5W so that is 2.5W for the five. Brake light at full brightness is 6W. License plate light is about 0.5W. If all were on, that is a total of a 13.2W, as much as it takes to light all of the meters lights and one indicator light on the stock system!

There are some calculations in this thread:
http://www.ninjette.org/forums/showthread.php?t=31087 that is linked from our main DIY sticky in the 2008+ tech section. They came up with quite a bit less available power, at least for the '08-'09 bikes.

I'll change the original post to reflect this. It does show that converting everything but the turn signals and headlights to LEDs can save you a pretty hefty amount of power (~36 watts). I just noticed that he wasn't able to get the Igniter draw. Would be interesting to see how much the igniter needs to keep the bike running. |
