     SCA light meter readings

    The seneye light meter is located in the round window on the back of the seneye device. The light levels will change depending on the position of the sensor relative to the light source.

    The seneye connect application (SCA) gives you a live read out from your light meter, a seneye reef device.

    This powerful tool can be used to help you understand the light levels in your aquarium giving you an output of PAR, LUX, Kelvin and a Calculation of PUR.

    To access your light meter output click on the output light tiles like below:

    This will open the detailed page for the light meter output which is shown below:

    The values for PAR, LUX, Kelvin and PUR are shown along the top of the screen. If you are not getting a Kelvin reading and want to know why click here.

    The graph on the left gives you an indication of the spectral output from your lighting.

    The graph on the right shows the Kelvin output of the lighting. A Kelvin is any point on the black line. If the colour is not a Kelvin, then the point is not shown.

    If you click on the 'Top', 'Middle', 'Bottom' or 'Free' button then the device will count down from 5 and then take a reading which will appear on


    If you have selected 'Free' you would have been prompted to name the readind and it will appear under 'PAR custom Readings' like below:

    Please bear in mind the seneye is intended for continual use. If you are only using the seneye to read light levels every now and again, please ensure you take the following care precautions:

    1. Ensure the device is connected to the SCA once every 30 days even when not in use for AT LEAST 8 consecutive hours.

    2. Keep the seneye stored in a clean and dry place when not in use

     Move the seneye device around the aquarium to read different light levels

    The seneye light meter sensor is located on the back of the seneye device in the round window. To read the light levels in your aquarium this will need to be positioned at the point where you want to take the reading. The reading on the SCA will update in real-time so you can get an idea of the different light levels in your aquarium and see how position and depth affect the output. A guide to the output can be found here for freshwater & here for marine.
