PAR64 LED and PAR38 LED shoot-out with 6" Fresnel; guess who wins?

LED Comparisons


Having recently purchased, for my own use, a “generic” Asian-manufactured PAR64 LED ($119 from Solaris: http://www.solarisnetwork.com/led_par.php) and a Chauvet COLORsplash Jr. ($49.99 from Centerstage: http://www.centerstagelighting.com), I thought a comparison between them and an “old skool” six-inch Fresnel might be interesting.

What follow is, as always, a non-scientific study of fixtures in my home’s garage.  My 10’ “pipe” of Unistrut is getting crowded!  Eventually, I’ll do a VectorWorks plot.  The Westlite 8”FS may have to be struck, as it’s missing its innards; but everything else is fully functioning.

Here are the foot-candle readings at fifteen feet:

 

 

 

 

 

Unfortunately, I didn’t have any R26 or R90 color media to put into the Fresnel.

A bunch of pictures follow, most are self-explanatory, but I’ll caption anyway.

500W, 6”Fresnel, No Color, spot focus.






PAR64, RGB @ FL, camera set to “Auto white balance.”






PAR38, RGB @ FL, camera set to “Tungsten.”  Color fringing on the edges AND in the center of the beam.  Could not be used without some sort of frost, and no provision for a color holder.





Next, and sometimes more important, is how the fixtures look from the front.  LEDs @ 10%.  Here is the Solaris model.








Chauvet COLORsplash Jr.; LEDs at 10%.  Note that the RED has it’s own row, and the GRN and BLU share rows, yet the RED was the least even color.








PAR64 purchased from ebay last October, for $151 delivered.  Came with absolutely no documentation whatsoever.  Has an LED display for setting address and modes, but I don’t know what any of the modes are.  All LEDs are visibly lit even when sending zero on all DMX channels.  I suspect this is to smooth the dimmer curve and eliminate some of the “steppy-ness” for which LEDs are known at low levels.  This unit has a significantly narrower beam than the other PAR64 can, as well.  It's a shame I can never be sure of buying another like it, as it would make a great truss warmer.








I hope someone finds this article helpful.  Derek.
