My 400W metal halide Thor modification is now ready. This is a seriously fun toy even if it's a backpack system. Here are some pics.
But first the main specs.
- 10MCP Thor serves as the host
- 400W PAR64 metal halide (short arc) lamp, about 30000 lumens and 6000K by chinese manufacturer, 700 hours life
- 400W electronic 110 VDC input ballast from china, has also dimmer function with potentiometer something like 50-100% power, didn't take advantage of this yet, but it works...
- Battery pack is made of 15 x 7.2V 3000mAh Nimh Sub-C RC batteries, 120 volts when charged
- Runtime limited to about 20 minutes so not to kill any of the 90 Nimh cells in the pack, once tested full 30 minutes, and batteries were not empty still
- I charge two RC-packs in series and with two chargers thats 4 of the 15 packs charging simultaneusly
- There is a volt meter, on/off with one of Thors stock swiches, connected to 12 RC packs, I use the ground wire in the 3-pole power cable to get this signal from the batteries
- 80mm fan cools the lamp, can be swiched on/off with a button, blue led indicates if fan is on
- 2 x 40mm fans in the ballast
I quess that's it. :devil:
Or did I forget something...
Battery weights about 5kg. No problem with a backpack.
The 400W electronic ballast has been bolted under Thor's belly. Thor is actually sitting on it.
I opened the ballast and drilled three holes to the aluminum top plate to allow sturdy fastening with screws and nuts under Thors belly. Also the ballast internals can be seen in the background.
The 400W metal halide bulb, about 30k lumens and 7mm arc lenght.
There is some fire proof fiberglass fabric installed between the PAR64 lamp and the plastic parts to allow about 20 minutes runtime without anything melting .
80mm fan is used to cool the par64 lamp. Air is pushed in from the rear and warm air exits from the stock ventilation holes around the bulb.
Quick shootout between Larryk14 and 400W HID Thor. 200 meters to the target tree. Camera settings are 6" F5.6.
The HID thor gives much higher spot brightness but actually the LK14 might have better flood. This is what I wanted, more spot intensity and throw compared to the LK14 but still with monster lumens.
The white balance of camera was not locked. Maybe the warmer color temperature of the halogen gives it some advantage. The metal halide is about 6000K. HID beam appears more intense. Overall the good old Larryk14 is a suprisingly tough competitor but the HID delivers quite scorching hot spot.
I think next I will do something like 1000 meters shoot out, looks like the HID Thor 400W is more a thrower.
