Ok, these 700FFs are identical to reflector design of the 500FF but much larger in diameter. How large are they? A full 7.5" in diameter. I have owned the 500FFs in the past and I am very familiar with the light pattern and distance the 500FF throws. Now that I have driven with these 700FFs with the same type and wattage of bulbs I have to say I like the 700FF over the 500FFs (IF YOU HAVE THE ROOM). If not, then go with the 500FFs.My experience with Hellas is very simple, I've used them on my cars and Landcruisers exclusively since 1985. They make damn good driving lights both on and off-road. I say that the 700FFs in stock form do a nice job in the city. However, if you do any off-roading AND these are the only auxiliary lights you have, then I would recommend upgrading the bulbs to a 100W or 130W. Don't buy knock-off bulbs, only use Hella branded bulbs. Why, because I have personal experience with the cheaper offerings and they DO NOT last as long nor are they as bright. Of course the modification to the higher wattage bulbs will make them unusable in city driving. But why would anyone need or use them in city driving anyways where the ambient street lights are more powerful than the wattage of the vehicles headlights?This version of the 700FFs are the Fun Cubed reflector design with plain glass front. Personally I have adopted these as fog lights with crystal ion fog bulbs from PIAA. The PIAA crystal-ion bulbs and Hella 700FFs are a perfect match and work great in snow and dense fog.I know some of you are thinking why didn't I just buy the fog light version of the 700s? I can tell you most ALL "fog" reflector designed aftermarket lights perform poorly in heavy dense fog or heavy white-out condition snowfall. For some reason they all emit light above the height of the hood of the vehicle. In fog, this causes glare, in heavy snow it's even worse!This is especially bad in heavy snow conditions where the visual effects are so impairing one feels as if one is on the Starship Enterprise and is going through a bad warp drive initialization with stars floating in front of you and towards you in a streaking fashion. I have never experience this effect using the 500s or the 700s with the PIAA Crystal-Ion bulbs as fog lights. The combination is simply awesome.I think my opinions are valid because I drove in blizzard conditions for 6-years in the winter months where they get 250" to 305" of snow per year! That is no joke.ADDITIONAL INFO: I have a FJ Cruiser with a grill guard where these puppies are mounted on the lower crossmember close to the ground. This is the best place for FOG LIGHTS. However, a pair of 700s are not enough to illuminate the back roads of the Upper Peninsula of Michigan where I drive at night. If you want to get excellent illumination I HIGHLY recommend the Hella Rallye 4000s with the Hella 130W optional bulbs. I have these mounted above the 500s on the top crossmember of the brush guard (same height as the factory headlights - optimum mounted height) . When you turn the 4000s on at night I will guarantee you that you will see EVERYTHING in front of the vehicle to 1/2 mile!

Great lights, I wish I could have found a flood beam, but these show further than the fog lenses do. I mainly wanted something that just lit up the night, but these work well enough when aimed right. The housings are tough, they stay adjusted and don't move. The covers are durable, look great when in place and remove easily, replace with a tad more difficulty, but won't come off unless you want them to. Since the lenses are glass, it's important to use the covers when not using the lights, to prevent pitting from sand and chipping/breaking from rocks, to get the most life from them. Mine are wired independently of the headlights; the instructions show how to wire the spot beams (like these) so they come on with high beams (plus they have a switch so they stay off); the fog beams are wired to come on with low beams. With the beams aimed so the centers touch the road surface at 50-75 yards in front of you, they do a fantastic job of augmenting the high beams, or can be used without headlights at all to see at a distance. the pencil beams just don't do very well at illuminating the ditches close-up, unless you specifically aim them that way, but then they don't help with distance. Great lights, and I don't see how the LED racks can do the job like these do.

Most impressed with these lamps. Well made and sturdy. Come complete with everything you need to fit them, including a relay and full instructions. The light output, even with the 55w bulbs supplied, is quite startling. I was worried that the beam would be a 'pencil' beam, but this isn't the case. The light, although stronger in the centre, spreads to the sides, lighting up the verges very well. I intend to upgrade them with 100w for offroad use. My only comment is I would have liked security bolts to be supplied with them or some means of making them difficult to remove. I'm sorting that out myself, but it would have been good to have had them supplied. Some manufacturers do this. A minor complaint, perhaps but it's costing me about £35 more and few hours of fiddling and drilling to fit security bolts.

I think I've purchased four sets of these lights for different projects or because I broke them. The most recent purchase was shipped in the display box that wasn't even taped shut. It looked like it rolled all the way to my house. Fortunately nothing was damaged and the lights are fine. As a side note, the 55 watt bulbs are easily swapped to 100 watt bulbs for even more power. Also, the clear polycarbonate covers for the Hella Black Magic lights will fit the FF700's.

First of all, look at the price and consider "value for money"These lights definitely improve on stock high beams giving you more reaction time when there is wildlife or debris on the road. They are cheaply made, hence the price, but they do a great job.Housing is plastic, covers are not easy to snap on/off and they are overall very lightweight.Comes with a complete wiring kit making installation a quick affair.These do their intended job very well at an excellent price point. I tried many LED driving lights on various price ranges and none of them come close to the usable light output of old school halogens.

One of the bust purchase for my car. Driving in night is bliss now it compliments headlamps very nice shows whole road upto 25ft. Speedbreakers are not a problem any more

I I couldn't have bought these lights and fixed them at a better time. I just did back to back long road travels one of which was at night on a 'potholed' national highway with vehicles zipping away with shearing headlamps etc. I was worried that I will have a tremendous amount of fatigue due to the night drive especially on my Duster which has ridiculously poor throw and angle of the headlamps. However, these Hellas ensured the visibility was perfect, and provided me with a comfortable view of the road ahead. The eye didn't feel the strain at all after the long drive. Thank you folks! If you ever come up with a 700FF White Light (12V 55W) variant please notify me.. :)

Installation was a breeze, find yourself a great wiring diagram and it shouldn't take long at all. Lights are sufficiently bright (read, street legal) when tied into your high beams and provide that extra little bit of security when driving down the road. The supplied wiring harness used 12g wire, and by some reports shouldn't have a problem handling 100w bulb drop ins. Brackets are nice and stable, and are not a problem to tighten up once you get the lights aimed where you want them (use locktite) Rock covers are kind of a pain to get on and off, especially if your lights aren't tightened completely down, but do provide protection against chips and the like. for $100 I wouldn't ever hesitate to purchase another set for a vehicle. The beam pattern wasn't quite as pristine as it could be, there's some hot spots, but not enough to make me not want to use these lights.
