Our light comes standard with all of the features that you would pay more for on competitive lights. Features such as a photocell which automatically turns the light off when the surrounding light conditions make the light ineffective... Sunny daylight hours are an excellent example of this. This feature greatly extends the life of the batteries as the light only operates when it can be seen. Increased battery life not only saves you money on batteries, but on the labor required to service the light as well. Another key feature is our 3-Way Switch. This switch allows a single light to serve two purposes. Each of our lights operates in either flashing or steady-burn modes. It only takes a simple turn of the switch to change the personality of our lights. Another cost- saving feature is that our light will accept batteries in any orientation as long as the springs are pointing up. There is no need to wonder if the battery is positioned properly, there will be no more batteries thrown out because it was thought that they were bad, when the real problem was the battery turned in the wrong direction. Compare our light to the competition and you will see that we out-shine them every time. Battery not included.

Cobalt chloride crystals are commonly used in classrooms for chemistry experiments and demonstrations, primarily to study chemical properties and investigate reactions involving moisture and hydration. The most notable uses include:
-
Indicator for Humidity and Hydration: Cobalt chloride is a popular indicator for moisture because it changes color based on its hydration state. In its anhydrous form, cobalt chloride is blue, and it turns pink when it absorbs water. This property makes it ideal for demonstrating reversible chemical changes and teaching about hydration and dehydration reactions.
-
Le Chatelier’s Principle Demonstrations: Cobalt chloride can be used to illustrate Le Chatelier's Principle. By adding water or applying heat to the crystal, students can observe the reversible color change, demonstrating shifts in equilibrium due to changes in temperature or the presence of a reactant.
-
Testing for Water Presence: Cobalt chloride paper, which is made using the crystals, is used in chemistry and environmental science labs to detect water vapor in various gases or liquids.
Due to its potential toxicity and the fact that it can cause skin irritation, cobalt chloride should be handled with proper safety measures, including wearing gloves and protective eyewear.
