I'm not sure what happened with my order, or Philips, or their distribution network, but the bulb I received was definitely not like any Philips CMH bulb I've used before. ESPECIALLY THE SOUND..According to all the available specs, the quartz ceramic capsule inside should be the exact same one I've been using for years in the T-12 150W/942 version, and this appears to be a genuine Philips product. Only thing is that of my Ceramic Halide bulbs from GE or Sylvania and Philips have never once been stamped "Made in China" right on the bulb. Its definitely new and unused, but goes through all the warm up stages that to me mean EOL is coming up. And it's hard to describe, but the color just doesn't feel like a 90+ CRI.The absolute worst aspect of this bulb though is the sound. I've never once had a $50 light bulb built so cheaply that you have to tap the fixture to quiet down the bulb. Now I read about others' having a similar experience with this bulb producing a high pitched "buzzing sound" when fully warmed up, and it was always blamed on the ballast. In hindsight though, these bulbs are generally very durable in my experience, and if you get one of these and tap it gently with your linger and hear a vibration... Return it asap! You can sometimes quiet them down (like I did by accident from the start) and stop the sound temporarily by adjusting the position/orientation if feasible. But after needing a very concentrated source of "daylight" on a lathe, swapping in this bulb/ballast/reflector... and, honestly, with nothing else running the sound becomes unbearable after an hour or two. Sorry Philips and whoever the seller was, but you permanently lost a solid customer.
