Here is a quick look at some of the parameters of for the LED. This one is rated at 90 Lumens and comes with an aluminum PCB as a heat sink. Let us start with a simple 1 W SMD LED like the one available from Adafruit. This means that for a 5-degree spot the source needs to increase by a factor of 8 to seem twice as bright and a point source, needs to increase by a factor of 4 to seem twice as bright. For a 5 degree spot the exponent is about 0.33 but for a point source, it is about 0.5. Perception of light intensity follows Stevens’ Power Law with an exponent that depends upon the amount of your field of view occupied by the light. In reality, human eyes are logarithmically sensitive to intensity change which means that doubling the intensity will be perceived as a small change. So how is brightness perceived? Logically speaking, when you have two LEDs lamps of 100 lumens each, the result should be double the brightness. On the contrary, a disco light will require fluctuating intensities of various colored LEDs. A lighting application such as a work bench light will seldom require a romantic mood light control. In any case, it is essential to have a clear understanding of the end application. A little further down the line, it comes down to brightness control and then mixing of colors to produce any shade from the color picker. Most newbies will be interested in making an LED glow without blowing it up. Let’s take a look at the problem and then discuss the solutions.

An efficient driver can make all the difference if you plan to deploy them for the long-haul. The idea is to be able to effectively control the brightness of the LED and prolong their life while doing it. There is no “one size fits all” but I will try and generalize as much as possible. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods.
