I have a K2 Viper 150w HQI clamp on light fixture for sale. Asking $125 plus shipping. I have two bulbs for it, the one that's in it now is a 14k Phoenix of undetermined age but it still is pretty bright so I'd say you'd get a few more months out of it, the other is a 20k Radium which has about 10 months of use on it and you may be able to squeeze another month but in all honesty I'd just use this bulb as a stopgap between bulbs. I will try and get some pics up as soon as possible but in the meantime if you want pics email me at: [email protected].
