Is the ANSI standard used to measure the light specifications? (I'm comparing the Supernova 300 with the Rayovac Sportsman)

I am not sure. However, the light appears to put out that much light. It is very bright. So far, the output seems to be appropriate for the claimed amount. My reason is that it compares favorably with a hand held flashlight that puts out 300 lumens. I have several with various outputs. This light is very effective for camping and for emergency lighting.

I'm not sure what you are asking. I am not an expert. However, I have purchased the Supernova and the Rayovac and like them both. I think they are very similar. The Supernova came in a box with instructions, while the Rayovac did not. The Supernova was a little easier to change the batteries, than the Rayovac. I haven't really used them, beyond testing. I purchased them for emergency purposes in case the power were to go out. I like both brands. hope this is helpful.

I have both. They appear to be the same lantern with different name labels. The Rayovac Sportsman 240 puts out 20% more lumens than the Supernova 300. I switched batteries and got the same results. I don't know why. The Rayovac is much cheaper.

I don't know, but my hunting light isms 150 lumens and this light is about the same. It does a good job on dark roads. The plastic holder could be better but for the price it is a good value.

I agree no light level determination. Something that could work that is also wireless WIFI and has an Internet app is the Spark Photon since it has something like 8 analog inputs. Would take some additional circuitry with a photocell but would seem to be very inexpensive for a hobbyist to do.

I've never tried the 21061, so cannot say how big the difference is. But with more than 1.6x the light gathering power of 21061, 21063 should be able to see more dark sky objects, like nebulae and galaxies. For terrestrial viewing and bright planets, there should be no big difference.

I can't explain how to measure the light and how it works in this small place, you can google it. The value reading on this measure is LUX, you don't need to use any conversions, you can read Lux value directly on the screen, but I have to tell you that the value is not accurate compare to the good one.Mine have problem after 1st week using it.

I bought mine for astronomy also. The red brightness is good for city astronomy and a bit bright for really dark skies. Too bad streamlight didn't allow the red LED to be dimmed like the white LEDs. It's still excellent for astronomy.

I have the Model LX1330B. The specifications in the instruction manual reflect the following:Light-measuring level from .1Lux to 200,000LuxAccuracy +- (3%rdg+10dgt) <=20,000Lux/2,000FC+- (5%rdg+10dgt) >= 20,000Lux/2,000FCRepeatability +-2%Photo detector lead length ~150cmSpectral Sensitivity- curve shows mostly betweeen 500nm and 650nmThe specifications page does not directly relate to foot candles, but hope this helps.

This should give you all the specs you need: http://www.menards.com/main/store/20090519001/items/media/Electrical/AmericanFluorescent/Prod_Tech_Spec/prod_YL108-YL108G.pdf

The bulbs specs. are on the bulb. The luminosity factor is on the bulb and on the specs. of the listingj

My ATN has no magnification. In perfect conditions (full moon) I'm comfortable taking shots at stationary targets at 50 yards. Using a 980nm IR illuminator works well. Source is invisible to the human eye but the scope sees it well.

Either standard or whatever you decide to use aftermarket. Unless you speak of the led's inside the unit, then I don't know

I am not really familiar with the procedure for testing aquarium lights, so this is hard to answer. The bottom line is that this meter will measure for comparison light readings, based upon differences in the source of the light. I hope this response is useful.

Paul, thank you. From the specs alone, I agree, but I think there must be some significant difference between the two sets. The only thing I can see from the specs is something about the eyepiece adjustment.

No it's not the same lantern but the body does resemble the Rayovac 3D lantern on the outside.The electronics inside however, that control the LED modes and the LED's themselves are different from what is used on the Rayovac lanterns.In other words the guts inside are completely different from the Supernova and they are really what run the light.

I don't know but the one the I had worked great in day light or when you could still see with your eye, but in starlight it was junk. Sent it back.
