When a cat with CSD scratches or bites you, the bacteria is transferred to your bloodstream, causing cat scratch fever. You can also contract cat scratch fever by allowing a cat to lick your eyes or an open wound. Cat scratch disease symptoms include rash, fever, headache and sore throat.
LUX is an abbreviation for Lumens per square meter. Foot-candles equal the amount of Lumens per square feet of area. So, that one candlepower equivalent equals 12.57 lumens. And for you figuring out LED equivalents, first you must know how many lumens your LED's each produce. Then divide that value by 12.57 and you have candlepower of the LED. You don't have foot-candles, remember foot-candles are illuminance.
A more realistic value may be nearer to 30 foot candles of ambient light. In this case, if we still use our. example of a 144 sq. ft. of screen area, then weâll multiply 144 by the new 150 (30 foot candles times. our factor of 5) lumens per sq. ft. number to get 21,600 lumens. 2,880 lumens in a pitch dark room compared to 21,600 lumens on the same size screen in the same. room with some lights on or windows shining light.
