what is the wavelength/frequency or other such comparison measure?

I'm afraid I do not know, but I can tell you that I sent this back because it never put out any heat. It was utterly worthless for me.

I'm not sure on the exact freq spectrum but owning one of these I can tell you it does not hit anywhere near as low as 60hz

Not that I've been able to find so far. It has a different tone and light for the beginning of the measure.

This device should be able to measure anything in the human hearing range. Note that some ultra- and sub-sonic frequencies can affect humans, but are not directly "audible".

Wavelength seems to be in the (most common) near-IR range of 850nm. Personally, I like the 950nm ones better, but they are harder to find and more expensive. I do find this model to be very bright (when viewing through camera) though I can't say for certain what its range is as I only use it out to 25ft.

do a 'google search: "LED light spectrum" for a wealth of info. not sure the purpose of the question.

It means N a radio-frequency band or radio frequency lying between 3 and 30 megahertz

This does not distinguish parts of the solar spectrum (infrared, visible, uva, uvb, etc) so probably not. I use it to check the overall solar irradiation level as measured in Watts per Meter^2 (which is generally from 0 W/m2 to 1300 W/mw on ground level).

This mini sound level meters comes with 31.5Hz ~ 8KHz frequencey range and 40~130dB, and A frequency Weighting. Hope this information is helpful to you.

Right and I believe that what he meant by that is that radio frequency is the far red area of the EM light spectrum. (600-800 nm) Radio freqency is often refered to as red and/or far red.

wow, I am not 100% sure if they use the same frequency, as I only have the one. sorry

The parameters are adjustable.l think mine came set at 1.2 max at the moment.There is also a graph showing a broader spectrum.Readings here are normally from .07 to .14,although l have detected some pasta products with slightly higher readings.There is a clicker which can be turned off,a reliability bar,color screen etc.A very nice instrument

I have no idea. You can probably research what FREQ they both use. Sorry, don't know.

There would be very little difference in operation. Only instrumentation would be able to indicate the difference. Hope that helps

Cannot answer your question exactly but suggest you look at the following link - https://www.youtube.com/watch?v=ZoeUgMFLyAw.It will give you a GOOD insight. For my use the meter is adequate.

Marc, why did you answer a question about frequency range by stating where you bought lights? No one has answered the original question and it is very basic information.
