1910.107(b)(10): Lighting Spray Areas Through Glass Panels
When spray areas are lit through glass or other transparent panels, only fixed lighting units may be used. Panels must isolate the spray area from the light, be noncombustible and resistant to breakage, and be arranged so normal residue buildup on the panel will not reach a dangerous temperature from the light.

Official text
(10) Illumination. When spraying areas are illuminated through glass panels or other transparent materials, only fixed lighting units shall be used as a source of illumination. Panels shall effectively isolate the spraying area from the area in which the lighting unit is located, and shall be of a noncombustible material of such a nature or so protected that breakage will be unlikely. Panels shall be so arranged that normal accumulations of residue on the exposed surface of the panel will not be raised to a dangerous temperature by radiation or conduction from the source of illumination. 19 citations

Frequently asked questions
Can portable lights shine through spray booth panels?
No. Only fixed lighting units may be used when lighting through glass panels or other transparent materials.
What must the panels be made of?
Noncombustible material that is unlikely to break, or protected so breakage is unlikely.
Why does residue matter?
Panels must be arranged so normal residue buildup is not heated to a dangerous temperature by the light.
