my daughters bedroom light fitting takes philips master bulbs, the number on the bulbs is PL-C 13W/827/4P i know 13W is the wattage and 4P is 4 pin, but what does the 827 stand for? im asking because these bulbs are so hard to find, and ive seen some that are higher wattage pl-c 4p's, but the number is different. does that mean they wouldnt fit?
