The parabolic side reflector focuses the light of the Petromax lamp in one direction. The curved shape of the reflector thereby creates a spotlight-like beam. At the same time, the parabolic side reflector also acts as a glare shield in the other direction. The reflector is attached to the lamp via two bracket arms next to the knurled nuts. The parabolic side reflector cannot be attached to the lamp together with the Petromax Top reflector.
