HID are quite difficult to get right as even tightening the mount up after adjustment can add or reduce penetration by several hundred metres. As well the mounts have to be really robust with a nice flat base and easy X&Y adjustment. If you go too cold then they are terrible in fog and dust and really don't perform terribly well at all. Actually not that relevant with HID it is the performance of the reflector and lens that is the key along with the colour temperature of the light. Sales people will talk about bigger being better and by that I mean power output. I have been running a set of Britax XRay vision HID for evaluation and they are pretty good for the price and have performed quite well so far but I am putting a new set of Predators on to do some back to back comparisonsĪ few traps with HID. We have been using Hella Predators for around ten years now and whilst at the top of the heap you get what you pay for. Check out several of the 4WD magazines who have done reviews over the last year or so. Sunday, at 16:52You will have plenty of choice in the price range for sure. Also, at 220mm diameter, I felt that they were obstructing air flow to the radiator. They provided no light to the road verges.I had reason to drive the Fraser Island beach one night and could only guess where the water's edge was. Their mass caused them to vibrate making the beam "dance" and reflective road signs became blinding. Incidentally, these lamps replaced my Cibie Super Oscars which were pencil beam.
In fact I am pleased at the non-slip feature of the mount. There was no reference in the documents to compensating for any incremental error in adjustment. I figured that if it was a problem then it could be overcome by inserting a shim under the front or rear of the mount, or fitting a rubber pad between the toothed faces. I notice that this mounting method is used on at least a couple of other lamps I have looked at. It may be a problem with a pencil beam but not here where the spread is greater. When I saw these I was concerned that my desired position may fall between the incremental teeth positions however this was not the case. The teeth prevent the lamp from slipping from the set position. The mounting base incorporates matching curved toothed surfaces for tilt adjustment. Sunday, at 12:03Hi Paul, I cannot find the review you refer tp but can guess about it.
