chipmaker Posted July 24, 2005 Share Posted July 24, 2005 When its stated its a 2x18, and it has 4 pins, is that two seperate bulbs each rated at 18 watts or both bulbs rated 18 together......I thought I had this lighting stuff figured out, but the more I read and look at it the more confused I get......... I notice some bulbs are 2 pin others are 4 pin....SOme have a artinic / daylight all in one assemby, so do both these come on together or are they individually switched? Link to comment
Daemonfly Posted July 25, 2005 Share Posted July 25, 2005 Nope, one bulb. In common configurations with electronic ballasts, the 2 left pins are just wired together as well as the 2 right pins. It basically goes in 2 pins, thru bulb, then out the other 2 pins. The smaller 2-pin bulbs have some parts inside the bulb base itself (starter I beleive), so they're wired with just 2 wires with a small mag ballast. Link to comment
