About the landlord's concern about "can halogen lamps be replaced by led lamps for annual inspection?" The following is my personal opinion:

It is acceptable to replace halogen lamps with led lamps for annual inspection:

1, LED is the abbreviation of English lightemittingdiode;

2. Its basic structure is an electroluminescent semiconductor chip, which is solidified on the bracket with silver glue or white glue, then the chip and the circuit board are connected with silver wire or gold wire, and then the periphery is sealed with epoxy resin;

3. It plays the role of protecting the internal core wire, and finally the shell is installed, so the LED lamp has good seismic performance.
