About a year ago I replaced a couple of my green LED's on my keyboard with blue ones. I only replaced the cap lock and the number lock due to the cost of the LED's(over $5 each at the time) I left the scroll lock alone because I never use it.
My question now is, I was looking at swapping these blue LED's with some UV purple LED's. As a test I just placed the leads of the UV LED's to the bottom of the blue ones where they are soldered to the board. I found that the UV leds would barely light up on the number lock and not at all on the scroll lock.I just recently got a voltmeter so I pulled it out and measured the voltage of eack of the LED's. I was somewhat surprised by the differance in voltages.
My numberlock voltage was 2.85v, the caplock was at 3.49v, and the scroll lock measured a lowly 2.0v. Now like I said the scroll lock has the orginal green LED in it. The other 2 locks have the blue LED's that I installed, both blue LED's light up well and are extremly bright.
Has anyone else noticed this kind of variation in the voltages on their keyboards? My keyboard is a Logitech Delux Access Keyboard model#Y-SG13
