Q How do LEDs produce light?
A In the middle of the LED SMD there is an N-type and a P-type semiconductor. The N-type has electrons and the P-type has holes. The holes and electrons rapidly cross the gap and then merge together. As they combine, it produces photons which in turn produces particles of light.
-
Q What sort of beam angle is produced by Ledodm's led strip lights?
A All of Ledodm's LED strip lights have a beam angle of 120°. You can use an aluminum channel with a special lens to change the beam angle is required.
-
Q Can Ledodm LED strips be cut?
A Yes, they can be cut to desired lengths.
-
Q Have all of Ledodm's strip lights been independently certified and tested for safety?
A Yes! Almost all of our strip lights are CE, RoHS certified, and ETL Listed.
-
Q Can Ledodm LED strips be soldered?
A Yes, they can be soldered. This is the ideal method to install led strip lights.
-
Q Do Ledodm LED strips have an adhesive on the backs of the strips?
A LEDs strip lights have a 3M brand adhesive that allows for a very easy and secure installation. For heavier outdoor-rated strips, we recommend using the silicone-mounting brackets for a more long-term mount.

Q What is LM-80?
A The LM-80 is one such standard. LM-80 refers to a method for measuring the lumen depreciation of solid-state lighting sources, such as LED packages, modules and arrays. LM-80 was created by members of IES including Philips Lumileds.

Q Functional Test: Electrical performance, Light efficiency performance, Color performance
A Function test used for cob led strip lights as below.
Electrical performance>>>Use Electronic Load or Multimeter to connect cob led strip to the power supply and adjust the voltage to the rated voltage, after the product working is stable, record the current and power data.
Light efficiency performance>>>Put cob led light strip into the integraing sphere and input with rated voltage, start the test and record the test data.
Color performance>>>Put cob led tape light into the integraing sphere and input with rated voltage, start the test and record the test data.
