We need a BLF lightbar!!!!!!!!!!!!!!!!!!!!!!!!!! for 4wds/4x4

Ok, so this is a bit of a sideways step from a torch (aka flashlight). Although the underlying tech really isn’t all that different.

At present LED lightbars or spotlights seem to fall into two main categories:

-Cheap and completely rubbish
-Hugely expensive but generally still with poor light quality.

Nearly all the lightbars at any price seem to have 6000-6500k poor tint & low CRI LEDs. Which frankly makes them a bit crap.

Is there anyone on BLF who could help make a BLF lightbar?

Of course there is potential for an entire range of lights. But let’s start off with just a middish sized lightbar. Say 20”, as it would be small enough to fit to a UTV/ATV or pretty much any 4×4. And you could always run a pair of them if you need more light for a bigger vehicle.

Must Haves:

  • 4000-5000k
  • 90CRI+
  • Good water proofing
  • Good mounting
  • No stupid blinky modes, just on/off
  • BLF pricing point

No sure on exact specs, I think that would be open for debate/discussion. Also would be housing dependant. But conceptually a 20” bar would give enough room for ten C8 heads or reflectors. If each housed a moderately driven SST-40 or XHP50.2 it should perform very well.

I don’t have the know how or contacts to even start a project off like this. So, I’m hoping there is someone on here who maybe has such a contact. Or would it be conceivable that someone like Manker/Lumpintop/Astrolux etc would be interested? Surely vehicle lighting is only one step away from flashlights. And I bet a lot of people would be very glad to buy a genuine good quality vehicle lightbar with good tint!

Here in the US, Mtn Electronics makes made some pretty good lightbars already… http://www.mtnlitebar.com/

Looks like they’re not taking any new orders, so it seems like your post is aimed in the right direction.

That kind of light would work on any car. I just hate those +6000k lights on vehicles. They just look so cheap, no matter what the other specs are. Wrong tint led lights should be illegal in vehicles, they are already crime against my eyes. LOL

Thanks. Didn’t know about those. Although they don’t seem to ship to the UK, so not an option. They also seem a little “premium” priced.

I like the idea of using multiple C8 reflectors, each with it’s own 16mm or 20mm MCPCB… so both the reflectors and LEDs can be easily swapped out.

Yeah, I was interested in theirs but they are pricy and they don’t seem to be doing them anymore. I would love to be able to buy a good BLF lightbar, I’ve held off on getting one for a while because none of the good manufacturers really make what I want. Your specs are pretty much identical to what I would want- 4k-5k (as warm as we can go without taking an output penalty) , high CRI, weatherproof, on-off only. A good mix of throw/ flood would also be a necessity for me.

A whole lineup would probably be possible. I would be interested in a ~12”, a ~50”, and a couple of cube lights depending on price.

Make sure it has lots of low frequency PWM too !!!

Maybe make every other one a speaker so it can be a light and sound bar .

Yes ridell tried making some and they didnt sell well. Everybody was hung up on price.

Seems people would rather spend big bucks on a flashlight, and run cheap chinese crap on their vehicles. I find that strange.

Thats the issue with a large light bar. By the time you get the custom parts and the labor of making one off lights the price is gonna be sky high. Most people aint gonna want to spend it.

Another issue is aiming for middel of the road stats or price point. The cheep guys will say you are price gouging and there lights aRe Gude’Nuff. The high end guys will just trash your product for being over priced imported crap made at the same factory and just charging more.

It is a no win situation for the manufactures. Even I would like a few light bars, I just don’t like the mounting options for my daily commuter rig.

If price will surely be an issue in a 20” light bar (with C8 reflectors/XHP50.2), I suggest just a shorter one that can house let’s say 4 reflectors per modular, EXPANDABLE housing, as nowadays a single C8 is already quite impressive compared to a pair of car OEM headlights.

I understand that to actually sell a light bar it would have to have at least the appearance of having a ton of emitters even if they weren't needed .  What about a mixture of high power and interlaced with B.S. cheaper  annoying colored emitters and a supersonic stupid mode which dazzled and hypnotized the less led literate .Maybe a moon mode of High Cri  5MM leds for map reading  Silly

This guy had what looked to be a great light bar going, but just fell off the map a year ago. Maybe got beamed up by aliens, who knows.

I’m keen. Need to measure if 20” would fit on a ‘standard’ nudge bar as well as a full on bull bar to keep the market open. I will do some measurements and come back.

I guess as a first attempt a 12” bar would work fine.

But looking on banggood, they seem to offer a selection all under $140
https://www.banggood.com/search/led-lightbar/3886-0-0-1-1-60-0-price-0-0...

Now don’t get me wrong. I know that those ones are likely dreadful.

But we all know that a good tint LED doesn’t really cost anything more than poor tint ones.

Just as we have with flashlights (Kronos X6, BLF A6, etc). I’m sure an existing housing could simply be utilised with different emitters and electronics. I was thinking for a 20” bar to be in the $120-300 price range depending on exact size.

I know this is all fantasy. But I can see it being feasible. And should places like Banggood want to stock and sell such an item (maybe with involvement from someone like Lumintop/Manker etc). Then I see such an item being potentially a good seller too.

I thought about this a few times. If I were to make it, it would be just to do it. There isn’t a way to make them cost effectively for the non-bulk manufacturer. Materials just cost too much.

You got me interested again though. I haven’t made a light in a while. I might put this on my TO DO List.

I have been thinking about an offroad lighting setup that uses fewer, higher intensity leds, and bigger reflectors, mainly to keep costs down but also to keep blinding stray light (spill) to a minimum.

My thoughts keep going to the SBT90.2 in about 2.5” reflectors… im guessing youd get around 400kcd, which would be pretty awesome. I wouldnt know how to power it in a 12 volt system tho.

Does anybody make a 25ish amp buck driver for 12-14 volts?

It would be much easier to just hook (probably 4) them up in series and direct drive. The drawback is that the light bar would have a multiple of 4 LEDs on it. Not really a big deal.

A bigger deal is the current draw. 18 amps x 4 is a lot for small alternators.

I like the idea of a BLF light bar. I don’t know a lot about the market though. I wonder if making a “light bar host” would be a viable option. Develop it so that people can finish it with standard light parts, e.g. c8 reflectors, carclo triple set ups, 20mm mcpcbs, etc. People can select their own optic/reflectors and led set up and then purchase those separately. That would help keep the price down. I think a really nice host with excellent heat sinking and maybe a few driver options would cover the parts that are hard to find or make. Not sure how feasible or desirable this is though.

Good idea.
Amp draw shouldnt be a problem- it would only be about 18 amps 12 volts. Even less 13.5.

A person would have to start with pretty small wire so as to not supply too many amps untill you figure out how many amps it will pull. Would suck to burn up 4 $35 emitters.

prbly would be easier to get a cheap one with a good heatsink, rip out crappy leds\drivers\optics, and build everything on that heatsink from scratch, but it wont be easy, it is nothing like building a flashlight, those things are exposed to elements, vibrations, temp fluctuations, much more than flashlights. there is a good reason why we almost never seen one,

I have already looked into trying to use an existing lighr bar quite a bit. The problem with the way they are made, is they have the led on the same board as the driver, and no room to have driver separate from the led board. So you’re forced to make something completely custom instead of using something cheap and off the shelf. Maybe I’ll build a prototype to try out a few ideas. Ive got the metal work down, but I’m not well versed in electronics.

I like the idea of using optics if possible, simply for the reason of not having the spill bouncing off of trees, fence posts, or the ground right in front of you and blinding you. But whatever i use, it has to have a wide beam but short from top to bottom. Most of the intensity needs to focus straight forward and gradually get less intense the further from the center you get.

That’s why TIR lenses are common among better lightbars.

Elliptical (“striped”) TIRs do exactly that.

Traditional reflectors are not a good idea if you are trying to reduce stray light. Larger TIR optics that are optimized to whatever type LED (eg 3535 vs 7070 vs COB) would be what you want.

Also consider a remote driver. This could solve a lot of packaging issues IMO, especially if its a multi-mode driver with in cab control. Only have LEDs and optics in the housing and plug into a regulated harness..

As for a B-as-in-budget ‘BLF lightbar’, I think the way it has to start is from people first modding what’s out there, developing drivers, figuring out optic/emitter combinations, etc. Then after two or three years maybe an open/crowd sourced design could be drafted and mass produced. If anyone designs something faster than that and of high quality, it ain’t gonna be cheap.

So, most of the shit light bars have a single thin as shit allu mpcb with all the circuitry and all the leds on it to save on mfg costs.

For this to get off the ground, we need
1. a mfg willing to do this.
2. a good starting point with the design, the simpler the better. if we can find a semi shit light bar, get a hold of the oem and say, “can we get x many of (base light bar) but with y exact changes” that makes things much easier and more likely to happen.
3. ?????
4. proffit

this is basically what happened with the eagle eye x6 GB way back in the day.

Looking at the Vf of a lot of emitters, it appears a good portion like the Samsung 351D, all the XHPs and rainbow Cree’s, White flats, sst/sbt, and FC-40 could work near their sweet-spot direct drive. Old Cree and Nichia don’t match up so well. A simple 12V linear driver could work with very low losses and therefore be able to probably be in a potted die cast aluminum enclosure.
