As there is no Parabolic Aluminised Reflector in an LED 'PAR', they would be more accurately referred to as 'LED flood lights'.
They can also be used as 'audience blinders' (lights pointed directly at the audience from a low angle).
LED instruments should have a long service life relative to other options, without the expense of colour gel or replacement lamps.
LED instruments are increasingly used for live music events, most notably festivals where they are more visible than conventional lighting under daylight.
[4] LED instruments cannot be used to create a hard-edged beam, which is needed for gobos and other effects which require the use of an ellipsoidal reflector spotlight,[3] though LED fixtures are now made that through the use of a small number of high-output diodes now allow the beam to be focused to a "hard edge", allowing full use of gobo/beam effects.
