M2-Plus H7 Motorcycle LED Headlight High/Low Beam Bulb Kit
 
Why does M2-Plus led bulbs have a lower luminous flux than others on eBay but actually glows better?
Please confirm the authenticity of the luminous flux and wattage of these products.
At present, most seller claims that their products have a luminous flux of 1W=200LM or above, but the current technology is up to 1W=140LM.
What's more, the luminous efficiency will decrease more or less for most led lights after a period of using, or very bright at the moment of lighting, and then the brightness will decrease after a few minutes of working, but for M2-Plus led bulbs, you can hardly feel the brightness drops at short or long term of using.
