Q:We have to develope LED outdoor  Luminaires with maximun 1%  of blue radiance. That is   betwen 300 to 379nm, must be less than 1% of the spectral radiance between 380 and 780 nm.

) `( ^' ]1 g! T/ Q7 YWe tried 2200°K led luminaires  and we obtain between 5 and 7 % instead of 1%. This luminaire could be possible to be used on middle distance to Observatories. But for short distance to Observatories , MUST BE LESS THAN ONE %.

So, we are looking that kind of led luminaires, and we think on   FILTERED LEDS to get less than one % of the blue spectral radiance.

What do you think, how to get that goal?

Please do your best to help us on this subject, is China manufacturing these kind of filters? 群里有人能帮我解释解释这说明意思啊，以前上的是政治专业，英语勉强及格
