just set the prongs under your light and the needle will move. most people know how much light they have. i dont use this feature because i dont need it.

Well that's a bit of a problem as the sensor is on the same side as the indicator and it is also very directional...but to get a consistent reading hold horizontally by the spikes rather than vertically as per measuring water/PH that way the sensor and indicator will be face up and place it in the general area where the plants will be...I'm not sure what the numbers mean light wise..they seem to roughly equate to watts when measuring a known source at 1 meter...

The adjustments are on the bottom of the "ball" at the bottom of the fixture. They are very easy to see once you look underneath the white detection screen. One adjusts the timer and the other how dark it must be for the sensor to function.

The face of the meter has a diagram of what the various lighting scenarios mean. If the left light is out and the right one is lit you have correct polarity. If the left light is lit and the right one is out you have reverse polarity. If both lights are lit the connection is open neutral and if no lights are lit the connection is open ground.

I grow orchids and use the light meter to monitor how much light they are getting. I do not have any experience as a photographer or in using this meter in that manner. Sorry. Dana

It reads both but the 2 I received did not work. One only read f4 regardless of how much flash was used and the replacement they sent me did not work at all. I will keep looking for an affordable light meter but will not trust this product. Hope this helps.

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.

It is only a reading of the current amount of light at the time the reading is taken. To gain insight into overall exposure you will need to take readings at 4 or so times during the day to get a sense of the exposure in terms of the measured area being one of partial shade, etc.

Look up the candle power to lumen ratios, an halogen bulbs are measured in candle power and LEDs in lumens

We bought a light to look at it....so I'm not sure if you could check it without the light or not. Sorry I'm not much help.

Probably nothing. If you can try looking at it from a different angle. The one I had, had a poor display that was hard to read unless you laid on the floor and shined a strong light on it. If it is new, I would return it.

Look at the directions that came with the light. It is all spelled out there. I recall it is pin. If you can't find, go to the companies website and ask them via "contact".

I'm assuming you are mixing two languages here, so I have no idea what your asking. It's a lux meter, if you are measuring light outputs, then yes you can use this. If not, you have no need for a lux meter.

Are you using a light meter and setting your camera to the values the meter provides? If not, that would be an awesome place to start....

From what I have read these meters do not accurately measure LEDs. I have LED lights and the meter reads 4500 to 7000 lumens but as you say that is a focused spectrum. My plants spend part of the day in natural light and the readings are much higher in the greenhouse.

It has a PC port while you can use to trigger a flash. However this meter has a mode that will let you flash your strobes within 30secs and it will take a meter reading for you. You simply activate the meter, hit the trigger for your strobes/monolights/flash whatever. Then it gives you the meter reading your looking for..

Their is not a meter per say. the only indication is when it is low the right led blinks.
