10wHID is the equivalent of 50w halogen. BUT you can use smaller batteries and get twice the burn time. Everyone knows this.
So if you used an equivalent light and had better results, how'd ya do it? What type of reflector do you have or use?
I'm just talking bulbs/reflector right now... The rest of the light just compliments what comes out of the bulb/reflector....
Well, wattage is all relative, it's Lumens that truely mater... take for example the U/K Light Canon... 10Watt HID, YET U/K themselves states it is equivilent to 25Watt, it also is a 6degree beam... my 24 or 27 (I forget the angle on my light) 50Watt halogen walks ALL over the top of my friends light canon... his is seen farther away because of the narrow spot, but he can be about 5-7 feet away from a rock, shinning his light on it, and I can be about 10-12feet away from the same rock, and my light will make his vanish (totally walks all over it)
Typically a small bulb doesn't put out much light... also halcyon states themselves that a 10watt HID is almost as bright as a 55watt halogen, at "~500lumens" now, the bulb I have in my Halogen light... about 800lumens... the tighter spot halogens are around 850lumens, and the wide angles around 750lumens...
That said, a used halogen canister can usually be picked up around $150+/- that's how I got mine.
HID actually produces around 600Kelvin colored light... daylight is well 5500kelvin (it varies by time of day, but 5500k is what daylight film is balanced for)
Now you can actually get a filtered MR16 bulb that is daylight balanced... or you can get 4700kelvin MR16's basically the difference between halogen and HID on video is not either way going to be per say better, it is dependent... if you wanted to warm the scene Halogen would be an easy way to do it... also it is very easy to filter halogen to 5500kelvin, where as I don't recall seeing a 6000k to 5500k filter, and 500k can make a difference look at how photos taken in the morning compare to noon or evening, the color shift is noticable with minimal change in light color...
Just my 2 cents, you can take or leave it. It's very possible I don't have a clue what I'm talking about... feel free to correct me if I truely made a mistake or typo.
