Masterful Instructions
Begin the lighting audit by accessing the attic or crawlspace entry point during a period of low ambient light to determine if the primary path of travel is safely illuminated for emergency or maintenance personnel; use a high-lumen flashlight to identify the switched light source required by building code to be located near the attic equipment or mechanical systems; verify that a permanent light fixture is installed within 20 feet of the HVAC air handler, water heater, or secondary electrical panels to provide a minimum of 30 foot-candles of direct task lighting; look specifically for exposed bulbs or temporary drop-lights that lack a protective wire cage or shatter-proof globe, which poses a significant fire hazard if broken in the presence of combustible insulation; examine the pull-chain or toggle switch at the attic entrance to ensure it is mechanically sound and not arcing or seizing due to extreme temperature fluctuations; check the mounting of all junction boxes and armored cable (BX) or Romex runs to confirm they are secured to the framing and not dangling where they can be tripped over in the dark; inspect the bulb wattage to ensure it does not exceed the fixture's rated capacity, which can cause the internal wiring to overheat in the confined, high-heat attic environment; finalize the audit by verifying that a convenience outlet is located on the same circuit near the equipment to allow for the use of power tools or diagnostic sensors without the need for extension cords trailing through the hatch.
Swap your old incandescent bulbs for High-Lumen LED Corn Bulbs; they provide five times the light at a fraction of the heat, which is a Gold Standard safety move because a 100-watt glass bulb can reach 400°F and instantly ignite cellulose insulation if the fixture is knocked over.
