I replaced another one last week. Had very little use, still worked, but was so dim as to be useless :-( Replacement was lower wattage (15W Vs 20W) but FAR brighter!
BTW is anybody using the Embertec AV switch the government was conned into supplying to reduce GHG emmisions? Got one a few weeks ago, and it wants to turn the TV off every time you switch channels, after flashing for only a few seconds. Swapped it for another one, and it does exactly the same so obviously a design fault. Now if I paid for it I could demand my money back, but since my taxes paid for it the company gets to keep the money for faulty products. Designed in Australia, I guess that's what happens now we have almost no electronics industry, what's left is the dregs. A typical marketing company with no technical capability :-(
