Can the light output be made brighter by replacing the LED with an incandescent bulb?

0

An incandescent bulb, as implemented in most conventional flashlights, is highly inefficient (<15 lm/W; <5-10% power efficiency) and requires much more power than an LED. An incandescent bulb has a lifetime of only 300-600 hours. It illuminates mostly infrared. Its glass envelope and filament are extremely fragile. Quite frequently, a bulb will break before it burns out. It also easily raises fire hazard, burnt-fingers, and maintenance problems. By comparison, the LED used in our products will last tens of thousands of hours and is nearly unbreakable for more than 11 years of continuous operation. On the other hand, rapid advancements in the development of AlGaInP, AlGaInN, and InGaN material systems over the last decade have paved the way for visible-spectrum LEDs to compete directly with conventional lighting technologies in many applications. The efficiencies of the HB LEDs implemented in our products have now exceeded those of incandescent, halogen and fluorescent bulbs.
