LED PAR-Spots are special spots that feature a normal E27 socket. Therefore, replacing the bulb is very simple. PAR stands for "Parabolic Aluminized Reflector" and the reflector is available in different beam angles that suit your application. PAR lamps are mainly used for projectors in high ceiling buildings, such as theaters and showrooms. Halogen PAR bulbs have high wattage, so switching to LED is very interesting.
