Nice response. You get more clever all the time.As usual, you're full of shit. Low frequency ballasts will strike and run CDM/CMH/LEC lamps just fine, otherwise why would my MAGNETIC ballasts work?
Low frequency ballasts are cheap to make, square wave units are more expensive. Any electronics tech will confirm this.
The cheap knockoff makers are counting on people making assumptions like you just did.
Be certain you get a square wave ballast to ensure best performance with these lamps. I've personally seen knockoffs that aren't.
I have no idea what incorrectly used ballast can strike which bulb.
The new 315 cmh with the new base not the old mogul base like the 400 and 860 are designed to operate only with a square wave low frequency ballast.
And it is also designed to be used in an open vertical mount reflector for max usable light.
There are quite a few brands that are not Phillips that run this particular bulb that this thread is about and they all run the new bulbs just fine.
The bulbs have vastly different performance like bulbs always have.
And the only reason the 315 watt bulb can compete with a higher wattage one and have enough gas pressure and heat to supply the better spectrum is the square wave ballast as opposed to the pulsing and peaks of an old style even electronic ballast.
But I am glad you are warning everyone. I asked to see an example.
If we are talking about a hundred bucks compared to 400 buyer beware.
