First, you need know what's relevant parameters you want test such as Lumen, CCT, CRI, distribution intensity curve, IES file, EMC/EMI test and so on

Second, you should find suitable instruments to match your LED light, that can test these parameters

Third, you should know some relevant internation standards, such as CIE, IEC, IESNA, LM-79 Clause and LM-80 Clause.

If you interested in that, you can reference: http://blog.lisungroup.com

How does an led light bulb work?

LED's (Light Emitting Diodes) work on DC current, not AC, so the AC needs to be stepped down to an appropriate voltage via a transformer (probably only a few volts), converted to DC via a rectifier and filter (to smooth out the ripple current). there are a constant driver in side the 120V AC led light bulb , this driver transfer the AC to DC, so the led could work with DC.

How does a light emitting diode work to produce light?

A light emitting diode (LED) works by converting electrical energy into light through a process called electroluminescence. When an electric current passes through the semiconductor material in the LED, it causes the electrons to release energy in the form of photons, which are the particles of light. This process creates the visible light that we see when an LED is turned on.
