I was at a customers yesterday and she was complaining that the Chinese 100w BC lamps she was buying didn't last long. So I suggested one of the new range of TH clear lamps arriving on the market.
That got me thinking that I've already had customers fitting the 40w ones into enclosed fittings with a maximum lamp size of 40w - only to find the interior charred. How do the T2 lampholders cope as I know 150w lamps can cause difficulties. ------------------------- Norman |

There's a link with how much ventilation the shade provides.
But to be honest, even with no shade, and 60W and 100W lamps, I find that today's T2 fittings may last only 5 years or so before the shade ring, and with some cheaper types, the bayonet socket itself, begins to go brittle. At home, we've moved a lot of lamps over to CFL, so I'm waiting to see what UV might do to the plastic ! Guess they don't make 'em like they used to ! ------------------------- Eur Ing Graham Kenyon CEng MIET |
