Using this LED is easy. First, make sure you connect it to the appropriate voltage. If you're using a heat sink, the working voltage is 9V - 11V. Without a heat sink, use 7.5V - 8.5V. When you turn it on, it'll give you a super - bright light that's great for your robot projects. Remember, if you use it at full power, it will get very hot. So, always use a heat sink to keep it cool. To maintain it, just keep it in a place where the temperature is between - 20°C and 60°C. When not in use, store it in the same temperature range. And that's all you need to know to get the most out of this LED!
