I got a hold of some of these to use for signalling. They are 12V and from testing run at upto 350ma depending on the color.
The only issue is they are to bright and i need to dim them down a bit.
I’ve considered a few dimming options. The best one is most likely PWM. But i need to keep this as simple as possible as i will be installing 90 of these lights.
Adding a resistor in series could have a dimming effect but obliviously there will be a voltage drop and i’m unsure if it will just cut out if the leds are designed to run at 12 volts.
I found this resource on the subject.
It shows the use of a 555 timer to achieve this.
Can anyone recommend what they would consider the best approach to this?
Is there a simpler way of using a 555 timer other than whats show in the link?
Is it just wishful thinking that i could solve this by just reducing current with one resistor?
Since i need to install allot of these the less parts and circuit complexity the better. Even if that means using something other than PWM.
