Well I want to try and place this new 4,000 watt HMI I'm putting together into the 36 inch Gorilla and other searchlights like my new "World's Biggest, Brightest single bulb searchlight.
I may be putting this four thousand watt HMI 380,000 lumen powerhouse bulb into the Monster if things fit correctly. Slowly I'm getting this together. Four thousand watt HMI ignited for the first time with my homemade Tesla coil ignitor. May use a spark gap to connect to the ballast.:thumbsup:
I apologize, but one of my photo hosts has unreliable and unstable links, (Facebook based), and this caused a large amount of my photos to vanish over he last few days. Apologize, but with all the photos I posted I'm not able to update all them do to a variety reasons, mostly time.
(Sneak Preview) Here is a quick look at the Searchlight when half finished, using only a 100watt HID bulb. Eventually I did Upgrade to a 1200 watt HMI with the help of the IgnITEor.

First time ignition of the 4000 watt H.M.I. hi tech light bulb arc chamber. Now I just have to hook up the ballast with this home made Tesla coil.
One of my homemade Tesla coils with PVC and 1/4" bolt adjustable spark gap, 915 turns of bell wire on PVC 'tower' and high voltage 2 liter/ foil capacitor with bleeder safety resistors instead of $200 'bank capacitor' or equivalent.

Using a 12 volt NAPA parts relay as an 'interrupter' to "pulse" the steady dc current to act like the points of an old school car ignition allow the ignition coil to power the homemade high voltage capacitor, spark gap and Tesla coil tower. I also purchased the coil at NAPA.
Don't have to actually hook a wire to get the arc chamber to ionize...just having the Tesla coil in the vicinity ignites any discharge bulb in vicinity such as CFL, fluorescent, metal halides, sodium vapor and of course HMI.

First time ignition with homemade Tesla coil as the ignitor. This will be used in conjunction with a real magnetic ballast to regulate, ignite and operate the four thousand watt HMI bulb.
One of my three Tesla Coils. I have better designs but cost have kept me with this smaller one as the main working unit. The bell wire of the proper gauge and the wider PVC tube, makes the ideal coil very expensive. I also need to get an old school magnetic 10,000 volt ignition transformer or an old school neon sign transformer at 10 kvac output to power the Tesla coil more reliably than the 12 VDC car ignition coil used here.
Homemade Tesla coil cost far less than when I was trying to build one in the 1970's... Today internet demonstrates how to make high voltage parts like capacitor out of foil and 2 liter soda bottle and coil tower from plastic pipe and bell wire, for pennies that would otherwise cost hundreds of dollars if purchased. Estimated voltage, determined by length of spark, is around 250,000 volts
Five hundred dollars to build a Tesla coil back in the 1970's, and no guarantee of operating, I abandoned "Tesla" until a few years ago, thanks to the abundant information found on the internet.
The Gorilla will be literally 4 times brighter than most of the shots seen before when I had the 100,000 lumen 1,200 watt HMI in it. Arc tube on the 4000 watt HMI isn't even one inch, it's about the same as the carbon arc area of the 60 inch WWII light and almost as many lumen. One of my searchlights, either the 36 inch Gorilla, 50 inch Monster and/or the 72 inch World's biggest searchlight will have a beam very similar to the 60 inch WWII carbon arc searchlight! If I try the four thousand watt HMI in some of the other searchlights, the beam will be a little wider as the arc distance is 20mm.
