Lighting flicker meter
<< < (3/4) > >>
NiHaoMike:
I remember about incandescent bulbs that had built in diodes or something to drop the voltage in order to allow the use of a shorter but thicker filament, but they didn't achieve popularity before CFLs took over.

Hen Hao!, nee na? (OK, bad pinyin spelling...)
How did I end up here??

Oh, Ian, how about adding a color meter into the device? "two in one stone" stuff?

I was thinking of the latter. You can buy color meters that give corrections in Wratten filter CC (CC10, CC20, CC40)

But how about 3 digital readouts in in RGB respectively and an overall Kelvin readout display.
The flicker rate should be easy a simplified Scope...again, one of those minddso iPhone like units

If you proceed with the project please let me know!

Most lighting sucks for rooms. What I recommend is LED strip lights put behind molding to make aircraft style lighting that reflects off the ceiling, ran with either solid DC or like 500+ Hz PWM.

I did this to a room and you can't tell where the lighting is coming from and its real nice compared to having some overly bright object in your field of view like a lamp. I feel like a primitive when I have a single bright light in the room. Or if I can see anything emitting light.

Halogens are good too though if you have them as directional lighting in shrouds aiming at stuff like tables and kitchen counter tops.

It feels like actual daylight if its distributed and recessed.

This is a very crude smartphone app: VISO Flicker tester

Some manufacturers have spectrophotometers which also measure flicker, but not very accurately: Gossen Mavospec
