Strange Rosco Axiom and Cool Light LED600 comparison

[Bill Davis]

Many years ago, when LUX first started being bandied about as a measurement of light output, it was primarily a marketing term that meant different things in different contexts.

(kinda like “watts” in audio – where a “1000 watt audio system” could mean anything from 1000 watts of “instantaneous peak power” to the more engineering reliable 1000 watts RMS ( measured as root mean square over the full audio spectrum).

LUX in the early days was similarly “fuzzy” as a useful measurement because it allowed for way too much Fudge Factor – even when used by honest manufacturers who had fine products but were forced to try and pick among varying “standards, for publication.

Both companies you mention publish “photo metric” data for their products – which show brightness measured in standard lumens over distance at various color temperatures?

Thatt data is a MUCH better picture of what a light fixture produces.

FWIW.

Hi,

The two products mentioned are completely different so its kind of apples and oranges. The Cool Lights product has 600 LEDs (just like miniature spotlights) trained outwards to form a large flat spotlight. The Axiom is an edge lit panel where the leds are trained into a diffused acrylic panel to produce a soft output similar to a softbox. Two completely different products for different uses and yes the spotlight will have more throw and power at a given distance than a diffused soft light will. Hope this helps.

Sorry to delay getting back to this. I did purchase 2 Cool Lights and so far have been happy. I say “so far” only because I haven’t used them too much. I was able to do a side by side comparison with a Lite Panels 12×12 and, for shear output, the Cool Light absolutely blew the Lite Panel away. And, to my eye, there was absolutely no different in the quality of the light or the color (both were daylight). It left the 12×12 owner a little wistful when we compared what we each paid for our kits.
