Does my Coral need strong light or weak light?  At what depth should they be placed?  The stronger, the better?  Or, the weaker, the greater?
This device "Answers" the question of all Coral Reef Hobbyists!  Where in the tank should I put my coral.  Seems like we all lose coral from simplying not placing our coral in the right area based on lighting and when it comes to lighting, just a couple inches off makes the difference. 

In reference the question, Neither of the above questions are the right answer! In fact, PROPRIETY is far more important than you can imagine ! For instance, the intensity of the lighting system affects the final outcome in most fields such as reading the lux levels of light at any given depth of an aquarium and will tell us as lights become weak and need to be replaced.  Appropriate illuminance will surely bring you the positive and satisfactory results!!

Here being viewed is a Brand New Digital LCD Light Meter ranging up to 200,000 Lux. or 20,000 FC - Far above natural sunlight measurement needed for coral lighting needs (see our chart on the definition of lux readings and how they compare related to the suns natural output) quite an essential tool to be used in many applications such as photography, science experiments, manufacturing, agriculture and artistry. Also, it is to measure the illuminance in any environment such as office, school, hospital, factory, hotel and store, etc. Do not submerse underwater unless you have a clear waterproof bag to keep all moisture out away from the cord and meter probe.  Measurements are typically taken in tank not filled with water or just measure along the outside of the tank itself as the light penetrates the water.  A 9V battery is also included so that it can be operated right upon arrival !!
