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.
400w HPS = 50000 lumens = 125 lumens/watt. 600w HPS = 90000 lumens = 150 lumens/watt. So you can see that HPS is more efficient than CFL...and as you get into bigger HPS bulbs, it becomes a lot more efficient. There's also fewer hassles with multiple cords and saved money on your energy bill. PAR watt directly indicates how much light energy is available for plants to use in photosynthesis. The output of a 400 watt incandescent bulb is about 25 watts of light, a 400 watt metal halide bulb emits about 140 watts of light.
