Ok, so I got my NovaTac 120P modded with one of the new Nichia NVSL 219 (CRI of 92) LEDs with a color temp. of 4500k. I actually liked the original SSC P4 LED, but thought it was important to compare a state of the art HiCRI LED with some filtered lights that have tints that make me very happy.
I used my filtered Fenix LD01 and filtered Jetbeam BK135a to compare with my unfiltered, newly modded HiCRI NovaTac. Both the Fenix and Jetbeam were at full power, while I tried to match the NovaTac to their power level and output, so around 65-80 lumens. My Canon G10 was locked in manual mode with DAYLIGHT white balance:
So, they look pretty close to my eye, with the Nichia 219 HiCRI LED being just a bit warmer.
It's important to note that the Nichia 219 becomes whiter as I apply more power. This seems to be common with current controlled lights like the NovaTac. It's also one of the reasons I have recommended in this thread for folks to check their filters at lower levels before settling on a particular filter. For instance, I tend to use my lights on the lower levels more than the higher levels, so I always pick my filters while on those levels.
So, what did I learn from this exercise? Well, this new Nichia 219 is a
very fine LED, and I think most folks will find it to be an excellent performer, however, it's still a bit warm for my taste (I'm exceedingly picky), so I've already added a -3/8 green filter.
Bottom line........
tint is a highly personal and subjective thing, and for those of us who have not only found that we like a particular tint, but also enjoy the convenience of using filters to quickly and easily achieve that result in any new light we get, I still think the Lee Filter Swatch Book is the least expensive, easiest, and best way to get that tint.
