Understanding Lumens

Historically if you wanted a certain amount of light you would buy bulbs based on their wattage rating. Wattage is a measure of energy. If you wanted bright lighting you might choose a 100 watt bulb because you knew they generated a lot of light. The measure of wattage was a simple way to quantify light when there weren’t many choices in bulb technology. When everything was the standard incandescent bulb, using watts was a great “rule of thumb” for comparison.

Cool running LEDs

Light-emitting diodes (LEDs) don’t like heat. Heat shortens their lifetimes. It also damages brightness, ruins efficiency and diminishes color. “Heat is death to an LED,” says Joe DeNicholas, Lighting Business Unit director for National Semiconductor. “There’s widely published data suggesting that if you keep the junction temperature of an LED at about 100 degrees Celsius, it will last for 80,000 hours. But if you let it go to, say, 135 degrees Celsius, the lifetime drops down to about 20,000 hours. That’s why we have to keep them cool.”

If you want your customers to see you as a partner, rather than a mere vendor, "let's build this together" is a superior proposition to "buy this from me." And who doesn't want to be viewed as a partner? So it's not surprising that joint research and development projects between customers and suppliers are on the rise. In its simplest form, joint R&D means that customers provide ideas and feedback while a product is being developed. They may also share costs and co-own the resulting intellectual property.
