Can you explain how it works, The units, Do I just place near the light source? Does it display exact reading in lux or requires some conversions and

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.

What do you think when you use the voltmeter to measure the voltage of the outlet in your house and the meter keep showing the voltage value changing all the time for example 100V then 110V then 90V then 120V (I know for sure 120V at the outlet by measuring with a good Voltmeter)????

Sorry, but I don't know the answer to that. The Heath/Zenith unit that I bought failed right out of the box. The clamp that secured the light socket would not tighten down. It failed because it was made of cheap plastic. When I called customer service, they hung up on me. Needless to say, I returned the unit for a refund. I went to an electrical supply store and got a better unit there for only a few dollars more. Well worth it! I recommend you stay away from Heath/Zenith.

John - Sorry I can't tell you the lux output. It was advertised as full spectrum light and puts out approx 1400 lumins. Hope that helps.

When you use it with the little white globe thing, you hold it up against your subject and read the light from there. That's really what this is for. You can also slide the globe out of the way and use it to measure reflected light, but that's going to be fairly inaccurate (since it is hard to point a meter like this with any degree of precision). But still, you point it at your subject, press the button, then look at the reading.

Sorry for responding late, but I did not have the lamp at immediate reach. Now, I verified it, and you are right. Mine is not working, either. I refer to center LED labeled #58, with the tag 730, which does not turn at all when all the rest do. Somebody could say that 730 (nm, I suppose) is beyond the range of human visión, but I guess that at least a dim red light glow should be emitted. Regards. Alvaro.

This meter only measure lux which can be converted to footcandles. It does not measure total lumens.

Sorry I can not answer that question at this time - last week I sent both units back for an exchange because both have failed. They should be here sometime next week and I will let you know when I look at the light's information at that time.

I don't know about lumens exactly, but I measured the output with a light meter and it registers about 15k to 20k lux (1 lux is equal to 1 lumen per square meter, I think). They say 20k lux is legit for growing plants. I ordered 4 different types of grow lights, and this actually has the highest output (including a 60 dollar T5 setup), it just doesn't cover a whole lot of area, although definitely covers more than the other under $20 LED lights. I may buy quite a few of these.

I was not impressed. If you ever need bright lighting (i.e. for reading, etc.), then you may want to go with a higher-wattage version. The light is nice, but if you can 'see' the bulbs, they do have some glare to them as they are clear, not frosted. If you are just looking for something that will give nice ambient lighting, you should be fine with them, though. I ended up using these in open, recessed can fixtures above our downstairs bar and they are fine there - but I don't need a bright light in that location. Also - these are NOT dimmable, so if the lamp has a 3-way switch, you may want to look at other options. Hope that helps! I was not impressed.

Sure did. All of the clicking drive me nuts. I thing I have mine set at 5% tolerance and it fixed it. Going to have to find your own mix that works for your environment. It will pick up even the slightest light from like oven clocks to neighbors lights outside. It sees it all. My buddy had to leave his ir off and just use an external ir light. Good luck.

I buy a luxmeter of this brand and capacity, and has the ability to measure light from 0.1 lux to 200,000 lux, divided into 4 types of measurement ranges.

this interested me so i grabbed my meter on my lights goes from max of 800 ma full on to 10ma lowest setting but im not running a whole roll of leds. so far I'm real happy with this thing.I'm running accent lighting with it controller is rf so do not need line of sight to module.

I used this light in one event and for the second event few days later it still showed FULL and I knew it is not FULL. At some point in showed half and then empty and it died !! it seems to me the meter adds the life of each battery and give you the "total" as empty , half or full !! Test with one battery and I think you will get a better representation of what is left on that battery. On the color temperature I can not make a comment since I never measured it ( honestly I never paid attention). like majority of Chinese products it lacks the true quality, so I wont be surprised if I measure the color temp on mine and it is off by 900 or 800 degree.

Yes you can. The hardware first calibrates the light in your office or computer room. You can do this two ways. 1) if you have work lights turn them on and calibrate or 2) cover the eye of the hardware and calibrate to total darkness for an alternative consistency. I have two monitors my Mac and my Dell. The ColorMunki recognized both monitors and asked me to choose which one I wanted to start with. Brilliant! There are two settings Easy set up or Advance. I did it both ways and preferred the easy set up for less human error. Then it does it's thing. There is a great little visual guide book that comes with the hardware to walk you through how to open it. I can't stress how simple this is. And makes a huge difference. Finally, Calibrating is not a one time thing, you will be repeating these steps often. I've set my reminder for every two weeks. Most monitors are also intuitive and will shift according to the lighting changes in the room, a lovely feature but also just another reason you will continually calibrate. Good luck!

John - I can't give you the specific lumen values . . . from an 'application' standpoint, the light is adequate for reading or workspace lighting (in close proximity). It is not sufficient for general room illumination or outdoor lighting

Lumen measurements for any flashlight/light source are meaningless unless you have the raw data.This flash light with the "zoom" at max spread, from a distance of one foot, with a coverage area of 1.5 feet, using quality 3.7V 18650 Li-Ion bats:High Mode:*Initial lux 4800~4900 (450 lum sq/ft)Med Mode:*Initial lux 2600~2750 (250 lum sq/ft)Low Mode:*initial lux 680~720 (65 lum sq/ft)Multiply these results buy 1.5 to get a more accurate lum sq/ft number.Focused to a point at 1 foot, well over 90,000 lux (bright as the sun), but that's what makes it great.

For our application at the church that i pastor we chose to go with the myDMX software package and adapter which we got at Amazon as well. Reason being it appeared to be far more expandable than a traditional lighting board. It was very simple to get them up and running with a couple of basic scenes. I just chose a light profile (I used a generic one. They didn't have these in the list but I emailed support and they are creating a profile) dragged it over to the lighting scene setup which btw, told me each light address so i could set the corresponding light and then I just moved each slider to the color that i wanted. The generic profile only gave me 3 channels but I really didn't need strobing or anything fancy yet til i get the profile from support. Are you using software or a physical light board? I hope this helps. If I can help more please let me know.
