Phoenix 14k aren't made anymore. If you have one, it's the holy grail of double ended halide bulbs. Very similar in appearance to an overdriven 20k Radium. Ballast will also play a part in the spectrum (slightly whiter or bluer). You don't have options these days in the double ended bulb market. If you have this bulb, consider yourself lucky.
Double-ended halide lights with this feature are like the holy grail. Looking a lot like a 20k Radium that has been overdriven. Ballast will also change the range, making it slightly whiter or bluer. Nowadays, there aren't many choices when it comes to double-ended bulbs. Congrats if you have this bulb. io games
