Due to your profession you probably understand light and the use of it more then most other people Mike Also how people percieve different light conditions/scenes(Apologies to MuddyM if we are getting to far offtopic )
One real question is what do people actually need from spotlights or additional driving lights? If it is just to look cool/how many lights can I fit on the front of their Defender, buy the cheapest ones going. (They can save themselves money by not even wiring them up! We have additional lights on our Land Rovers but we do take them over very varied terrain. For additional driving lights i.e. long range use we use Lightforce 170s at bumper/a bar level. being mounted there switching them on does not give any glare to the eyes. Care has to be taken when using these not to blind oncoming traffic. The lights at roof level are wired separately from main light circuit so ILLEGAL for road use, but does give a completely separate light circuit if anything goes with main circuit These lights are wired as a middle pair and an outer pair. When travelling middle pair is normally aimed at road about 50 metresi in front of vehicle so can read the road better for potholes etc. Outer pair will be aimed so that I have better light spread to the side. Good for spotting sheep/roos etc which might dash in front of vehicle. Dependent on terrain/road conditions and weather conditions depends on what lights I use. Sometimes I 'experiment' with what lights give me best result for driving by. Remember you have to adjust your speed to keep safely within your lights. OK if you are comping in big desert areas at high speed at night yes you probably do need Lightforce 240 HID lights at something like £500 each. Not really needed for most UK road conditions Must admit Mike you have given me some ideas on experimenting with different lights Brendan |

Not sure what "raw" and "effective" lumens are Ken. Do you mean "initial" and "mean"?

Hi Mike, have a read here here
Basically max light output and max less all losses. Brendan |

Hm, not sure about that. LEDs typically lose 20-25% of effectiveness after the first 800-1000 hours of use. Probably not an issue with most recreational vehicle users though, but the "mean" output is the actual after the burn in period and that's the true figure (for what its worth, which is really not that useful either way).
The bottom line is that good lights aren't cheap, and cheap lights aren't good. The VisionX lights are really good quality, but for driving in this country, I can't ever see a reason (excepting work use under certain applications) to have auxilliary lights of that calibre. Then again (can of worms) I don't really understand the desire to have more lights anyway, the stock lamps on a puma are good with uprated bulbs like Osram or Philips anyway. And the old chesnut "I want a light bar so I can see when wading in deep water at night", well, WTF are you doing wading in deep water at night anyway? |

Great points. I wanted roof mounted spots to give a wide, deep spread of light when driving on small country lanes at night (I live in Snowdonia). I also do alot of loading, unloading and working around the vehicle after sunset. For this I have hella work lights on the side of the rack and to the rear. The product information for work light applications is generally very good.
For the roof rack I initially wanted 4 spots, wired separately, but operating together for the night driving applications. Like Mike I believe that for general driving the Puma headlights with uprated bulbs are more than effective. Who wants to be putting high beam on and off constantly so as not to blind oncoming traffic? I have cocked up with the roof mounts, they give a great spread of light but are too large and for this reason I will be swapping to some smaller Hellas with a suitable beam pattern when funds allow. I shall also be looking at Warn lights. I don't think you need to spend a fortune for UK applications, how many tractors / forestry machines have top dollar lights on them? They, however, are out in all weathers. I think there could be some serious mileage in a retailer doing so side by side testing and I for one would be very interested in the results. |
