140s V 170s Lightforce

I sell both and yes the 240 Blitz are big. The 170 Striker's will do the job for 90 % of the road users. Go for the 240's if you are off road 90 % of the time.

When I bought mine 3 years back I had the bounus of driving past the factory each day - dropped in for some good oil (they don't retail but). At that time, turned out the smaller ones had the very same 100W globe as the larger 240's - the 240's had a higher candlepower rating but the same energy consumption, meaning I suppose that the larger ones are more efficient at sending the light out there. I chose the 170's, due to bullbar design. Have been very good to date - they truly make the headlights on the Jackaroo (even with upmarket globes in them) appear as the proverbial glow-worms in a pickle jar ! Maths being what it is, we should be mindful of a small increase in diameter having a steep rise in the surface area of the lamps - the biggies would stop a lot of extra air flow.... but that may not matter. The ability to vary the focus, and to use clip on lens options are great overall.

Do yourself a favour & research other makes as well, especially from makes of long world standing who publish factual technical information and performance figures that are obtained from laboratory testing. Sure read all the sales blurb and wordy stuff that we all love to hear but don't make the lights perform any better and regarding comparative testing done by so called reputable 4x4 magazines treat it very warily. Re quality I am very dissatisfied with the globe performance on my 240's (they regularly get black "smokey" stains inside the glass which affects performance & beam shape) and yes, "they are operating on the correct voltage". Re robustness, that is debatable. For normal use they are probably fine but hit a roo or an emu and they just "explode", just ask any professional truckie. Since there are only really two parts that make up the entire lamp or at least are serviced as spare parts, you are up for at least half a new lamp every time. We have a couple of sets of Rallye 4000's operating on other vehicles in the family and I would use them every time for my money. Re using the excising wiring you need to run whatever lamps you get through a good relay and as large diameter wiring for the power supply and earth leads as is sensible say 5 or 6mm direct from the battery with an in-line fuse. That way you get maximum voltage to the lamps which is critical for good performance. Oh yeah and don't operate the lamps off a separate switch alone, always via the high beam so they ALWAYS dip when you dip your lamps in case you or someone else forgets to turn off the lamps when you face an oncoming vehicle. That way you can still turn the lamps off via a separate switch and have the vehicles high beam operating but whenever you dip the vehicle h/lamps the driving lamps will go out if the separate switch is on.

Yeah apparently the compact series have the same performance as the Rallye 4000's
Good Luck
