Hot news: staying cool is important
You’ve probably heard us talk about cool and warm lighting before, but that has to do with the colour temperature of the lighting. The cool part we’re talking about today is something very different. Did you know that every light produces heat? It doesn’t matter if it’s a halogen, incandescent or LED light, though LED produces much less heat than the other two. In short: it’s going to get hot and that heat needs to be off-set by a cooling element.
We’re sure you already know incandescent and halogen lights can get very hot. There’s a reason you don’t just grab one of those light bulbs with your bare hands. You can’t. And if you can, please don’t. The heat is produced when electricity is being converted to light. The conversion for these ‘old’ techniques is not very efficient: 95 percent of the electricity is lost and converts to heat instead of light. The energy efficiency of LED-lighting is much higher, but still about 50 percent is converted to heat, not light. LED-lights don’t get as hot though, because the heat doesn’t really go towards the light itself.
The biggest enemy of electronics
The heat can’t be avoided though, and that poses a big challenge. The biggest enemy of all electronics is temperature, be it very hot or very cold. If the temperature within a lighting fixture reaches 70 °C or higher, the functionality of the light has a high risk of failing. If not now then definitely somewhere in the future, way before the supposed end of the product lifecycle. The light will malfunction or even stop working completely.
The solution is relatively easy: just add a cooling element to off-set the heat as much as necessary, so that the temperature stays below a certain amount. You’d think that every lighting manufacturer would at least guarantee that, but the reality is not that simple. A lot of manufacturers want to keep the price of their products low. They use a smaller cooling element or one made from cheaper materials.
Quality over price
Though these products may seem very similar at first, you will see the difference after a few years. Or rather, you won’t see anything at all because the lights have probably stopped working. Without proper cooling, the components and materials inside of the fixture will start to deteriorate because the temperature gets too hot. And that can take years off the desired lifecycle. You’ve probably guessed already where we are going with this: our advice is to pick quality over price, if you have the option of course. It will last you a lot longer.
That’s not just a promise, it’s our guarantee. That’s why we provide a 5 or even 7 year warranty for our products. More about that in our next blog.Next blog
