THIS FIXTURE MAY BE INSTALLED HORIZONTALLY OR VERTICALLY. note....having installed many of these porcelain lampholders (fixtures) to replace melted or damaged plastic fixtures, rest assured, this porcelain base fixture is superior. extra care must be excercised during the install of any porcelain fixture to avoid cracking (just like a commode, don't overtighten). once your porcelain fixture is installed, be confident this fixture will not not melt or compromise due to heat. with a 660 watt maximum you may confidently use a high wattage bulb, up to 660 watts. i have preferred a big ge cfl, 55 watt, curly bulb that delivers 200 watts equivalent lighting (ge 78965). this monster cfl bulbs lights up the room, avoids any possibility of overheating the fixture and saves money too. since i sell everything i use, you can see the ge cfl bulb mpn 78965 go to my store and search keyword CFL BULB BID AND BUY HERE IN IN ABSOLUTE CONFIDENCE SINCE I HAVE THOUSANDS OF POSITIVE FEEDBACK.
