Low NOx burner
A low NOx burner (LNB) is a combustion burner that reduces nitrogen oxide emissions by staging the mixing of fuel and air within the burner itself.
Low-emissivity coating
A low-emissivity (low-E) coating is a microscopically thin transparent coating on glass or plastic that reflects infrared heat while transmitting visible light, reducing heat transfer through windows.
Low-emissivity glass
Low-emissivity glass, or low-e glass, is window glass carrying a microscopically thin, virtually invisible metal coating that reflects infrared heat while transmitting visible light, reducing heat transfer through windows.
Low-enriched uranium

Low-iron solar glass
Low-iron solar glass, also called ultra-clear or photovoltaic glass, is soda-lime glass with reduced iron content, the front cover of photovoltaic modules that lets more sunlight reach the cells.
Low-level waste
Low-level waste (LLW) is a category of radioactive waste that accounts for about 90 percent of radioactive waste volume worldwide but only about 1 percent of its radioactivity.
Low-level waste disposal
Low-level waste disposal is the permanent emplacement of low-level radioactive waste in licensed near-surface facilities, using engineered and natural barriers while radioactive decay reduces the hazard.
