I experimented with mixing Warm white and standard white leds in one flashlight. The resutls were quite interesting.
Findings:
I found surprizingly better depth perception and just ability to "notice" some subtle details. I compared my "mixed led" flashlight with a 0.5W Advancedmart standard white flashlight and there was a considerable difference. Some book cover details consisting of small variations of light brown color are only noticeable with the "mixed" led flashlight. I also opened the kitchen cabinet where we hold the spices and was surprized to notice more detail in the jars with the "mixed" led light. Funny, because the 0.5 W standard white light is actually a little brighter.
I can not explain well the "ability to notice details". It just happens :thinking:.
Maybe I am imagining things . Has anybody tried something like that?
Initially I experimented with Warm white LEDs only and found that they were dimmer and at least some of them did not provide good color rendition.

Implementation detail:
This was a low tech real easy mod.
I just added two warm white leds to a flashlight that had three standard white LEDs.
I used two 50 degree Warm white 5mm LEDs from the Led Supply.
The flashlight was a modified bonfire blaze. It has three standard white LEDs - one of the original LEDs and two more wide angle ones from Radio Shack. The Radio Shack leds were good at widening the beam.
I used a Bonfire Blaze, because it is extremely easy to replace the leds (remove cap and desolder/solder).
The leds seem to have similar Vf, because adding the Warm white leds did not change the brightness of the standard white ones. The warm white leds are not as bright and probably contribute about 1/4 of the overal light.
The Black tape on the outside of the cap is to prevent the LEDs from blinding me. The lower end of the cap is left open to light up the ground. The yellow tape on the inside warms up tint by reflecting yellow towards the ground.
The single dark LED is the "Low" setting one.
Question 1:
Ayone knows of a one or two AA battery flashlight with easy to replace 5mm LEDs?
I would like to experiment more. The bonfire blaze is quite clumsy light and not that cheap.
Question 2:
I am surprized that noone has offered (mass produced) a mixed led flashlight. What would be the reason? Peak Led solutions for example could probably easily offer it as an options. It would be ideal for doctors.
Last but not least - I can't help but notice: These are really nice forums. Always friendly, always helpful. Big difference from the photography forum I frequent. People there could easily turn from passionate to plain nasty. How do you guys manage keep the trolls away?
