Do you prefer RGB, RGBW, RGBA, RGBAW or maybe even RGBAW-UV?

Of course you have to consider the cost of more LEDs in the fixture as well....

This would be for an uplight application.....
 
When we bought our earlier this year, we went with RGBAW. We didn't feel the extra $100 per fixture for UV was worth it. Also, be sure that whatever you buy are all in one leds instead of individual diodes (the light-brite style).

With the UV added LED chips I have seen, it is really NOT the UV spectrum, but a close facsimile....and the power output is not very good, unless used within 10' or so of the object to "glow"

LED's are not quite capable of reproducing the UV spectrum, at all. I can see it being useful for some very specific saturations of color in a mix, but not by itself at the current time (but things may change in the next week or so).

For anyone else who wants to let me know their opinion, do you think having UL or ETL approvals are required for your use? (MET is another testing lab, and actually the oldest and first to fight the monopoly held by UL.....)
 
There are UV capable LEDs (ideally around 365nm wavelength) .. the issue is they aren't as efficient as most current LEDs, so of course, cost is higher and output not so. Most of the "UV" LEDs sold run in the 400nm+ range, which is at the tail end of the visible violet range, so they make white clothing shine, but you don't get the "pop" of a true UV. Current state-of-the-art 1.2W true-UV LEDs go for almost $85 in quantity. Since most fixtures use multiple 7-30w LEDs (some higher), adding true UV would cost thousands.

I have a ADJ UV Bar 16 ... it's neat at Halloween and I use it at bar events, but it's just barely in the UV spectrum (390-410nm).

I like for my stuff to be UL listed. It tells me that the manufacturer has decided to spend the effort to make sure that their gear meets a set standard of quality and safety.
 
I've seen some things, man, and some stuff.

Yeah, Steve149, does have it nailed...but the purple is useable in mixing saturations for very persnickety LDs who want more saturation in Reds, and even in some pastels it can be useable...thanks for the replies, I appreciate it.

I just noticed today that the yellow/green LEDs get fairly hot/hotter than the blue (and red, I guess), which don't give off heat at all...
