WebAug 25, 2024 · Essentially, you need 1/683W of power to create 1 lumen luminous flux (1/4π = 0,08 candela to all 1 steradian angles). Using above figure you need 900 times 1/683W = 1,32W to produce 900 lumen … Webpower it uses, the bulb gives out 14.3 lm/W. Each single watt of power used by the new prototype TLED produces 200 lumens. This means it would need less than 5 watts of energy to produce the same amount of light as the traditional 60W bulb. Why this innovation matters The 200 lm/W lamp compared to the most efficient lamp currently on the market.
