What is the flux of the general led daylight light
See how many wattage, generally 16 w LED fluorescent lamp at present is 1400 lm, luminous flux or new 40 w fluorescent lamp luminous flux highs, but according to the high degree is the LED fluorescent lamp, fluorescent lamp, 360 °, reflective part by stent, the light loss is very big, the LED fluorescent lamp light Angle generally around 170 °.
My own production of LED fluorescent lamp, single lamp 130 lm/W, if the light bead is 16.5 W, the total luminous flux can reach 2145 lm, efficient use of power supply in 90%, total power is around 18 W lights lit, overlapping there will be a loss, the loss and the printing ink of aluminum plate used reflective effect has much to do, usually in about 10% of the loss, add cover outside, usually the light transmittance of transparent cover is 94%, milky white cover transmittance is 75% to 75%, so in a transparent bubble of 18 W LED fluorescent lamp, for example, using the highest light LED, the total luminous flux can reach 130 * 16.5 * 94% * 90% = 1800 lm, the whole lighting effect of about 100 lm/W, quite obvious energy saving effect or hi
This depends on the quality of the LED fluorescent lamp, better leds luminous efficiency > 80 lm/w, that is to say, the 18 w LED fluorescent lamp luminous flux should be around 1500 lumens, 14 w flux should have over 1100 lm, 9 w flux to more than 780 lm. The poor quality is less than this flux, and there are tools that can be measured, very simple tools. There are also some quality LED fluorescent lamps that can reach this flux, and for a period of time the light is very bad, and there are a lot of poor luminescence angles that don't have the Angle of 180 degrees. LED918 has an article about how to buy LED fluorescent lights.
And you can do that, and you're going to have 7, 5lm per watt. If it's a 10W light, you're 75 * 10 = 750LM.And you can do that, and you're going to have 7, 5lm per watt. If it's a 10W light, you're 75 * 10 = 750LM.
