8" Secondary Cathode - Blue
The bulb here can be used as a secondary attachment to the cathode that you have now. This cathode comes with no inverter, just a bulb. You simply plug this light into your inverter and you are good to go. The best part about these bulbs is that when they are used with a sound activated kit they are sound activated, and when they are used with a normal kit they are normal. This cathode cannot be used alone, you must have a dual inverter. All of our cathode kits come with dual inverters.
