New lights from MRT

Nice!

Just remember, with these cannons, you can have any pattern you wish with all the different covers. Takes less than a minute to swap em out. THATS one thing I REALLY love about these lights. Some of the diffused don't work too great. Such as the amber diffused. But I think the clear colored covers would work best. I'll be looking into the clear amber covers first. For a spot beam in amber. The clear covers (non colored) in different beam patterns would work great too, such as the Euro or Elliptical. Might get those too!

 

hmmm will definely be something to look into. cant you change out the rigid ones as well?

i think you can unscrew em and throw a diffused cover in

 

I have the srq ambers with diffused on my hood. But idk if you can swap the lenses out. Even if so that's kind of a pain. But nice they added that option if so anyways

For sure these little srq's dont put out hardly any light at all though. I use them as dtrl's. But they aren't comparable to the duallies. Think those are much brighter. But, on a bad note, I just recently had some condensation buildup in one of the rigids! So I'm not expecting them to last through many more more rain storms before they peter out
Good news is I've had all my other China bars just as long and not one issue with those! And the cannons were installed during the last rainy day we had as well which was when the rigids were affected, and no ill effects.

Not trying to talk crap though, just stating a fact that i was kinda let down with rigid

 

my roof bar gets a ton of condensation so im getting a replacement with new OSRAM chips or something with 4d optics.

depending on the performance of the new bar i may be selling the bar as its not functional for my offroading habits. im always in high dust areas.

 

yes its very bad out here in the desert

 

Yeah I know I wish there was a way to really test them myself. I imagine my numbers are actually lower. For one, my evo primes clones are rated the same as the actual evo prime from vision x. Obviously that's not gonna be true when it's got different circuitry management and crees instead of luminus. The optics though on the other hand are the same exact vision x uses, as well as the housing. Two, vision x lists both raw lumens as well as theoretical lumens. I'm wondering if they, or anyone for that matter, can actually test the actual output. Perhaps that's why they all list them as 'raw' lumens? I'm not very knowledgeable on how they test them. I read up a little on lumen spheres. And I think they're only so big so you can't fit a full size bar in there. And Idk how those lux meters work but those don't measure lumens do they? Plus from what little I browsed online, those things are pricey!

Anyways.. yeah I do keep that in mind. But I just decided to list it like everyone else does. I basically consider it , as well as other ratings I see, as a base rating on the performance. because for the most part, even though they're probly inaccurate, it's a good starting point to judge the brightness when comparing to other bars. And I certainly agree there's lots of exaggerations on China bars. In their lumens ratings as well as over exposed pictures to make them appear brighter than they really are.

Do you know if there is in fact a way to test my lumens output? Either of each bar or total output? Maybe a shop or someone that has a way of testing it? Because that's something I would like to learn about and be able to test in the future. If all that's available is one of those lux meters, then I may be willing to invest in one. Although most light bars don't really specify lux ratings. I'll have to look into lux and learn how it all works and how it's compared to lumens ratings.. I see cheap ones as well as nice expensive ones.. Any input on the options for those too by chance?

Thanks

 

Hmm. Lux does sound like a better way to test for sure then. Because lumens seem like just a basis on how much light total is being put out, but the actual usable light will certainly be less. But one thing I'm curious on, is how you could measure that usable light... Seems to me with a lux meter, intensity will vary throught the light spectrum at different angles, as well as distances. But I assume that you'd be looking for peak intensity? Because you could have a spot bar, such as the light cannons that have a peak intensity straight out, and be comparable to peak intensity of a light bar. But with a full size light bar, you're gonna have much more usable light with a bigger spread. Seems like you wouldn't be able to test something like that, except of course the peak intensity. Maybe testing it at different angles? Like a lux rating for in front of the truck, and a few ratings at different angles out to the sides?

 

Great info. Thanks. I'll definitely have to get a lux meter then. At some point.. maybe I'll try one of the cheaper ones first. But will be hard to say how accurate readings will be compared to the higher end ones. Let me know what your friend says!

Because as you can see in that last pic I posted, I've got a pretty damned good spread of light imo. Of course that's all lights combined. But even the roof bar alone, is pretty spectacular, and has a pretty wide spread and lots of usable light. So when I got these cannons from chas, I was pretty impressed with the spill they gave off too. I was expecting a pencil beam alone... I had considered getting one of those 4d bars with osrams leds, but after seeing that even with a combo pattern, I was not impressed that it was still basically a spot bar. I had high hopes because they CLAIM to have 40k lumens. But the usable light isn't really much. It's a great spot bar and probly shoots down range good, but I like to have a combination of that as well as a nice flood spread with no hot spots. I think I accomplished that pretty well with my setup. without even trying I might add. ha. So these cannons certainly helped and gave me a bit more light down range. Even though it's hard to tell with all my other lights on at the same time. But after wiring them up temporarily with the switch and no other lights on, I was really impressed..

 

Cool. I'm really curious what kind of readings I'll get with my setup. The only question though, is finding someone with a setup that I can compare to. And I don't even have any buddies out here I suppose I could get a thread started when the time comes to call out people with lux meters to post some readings

 

Sweetness. Thanks man!

 

Bumpin for some sweet lights..

 

How do these compare to a 20" double row bar or a pair of the "Kragen" 4" HIDs?

I'm trying to decide what to run on the front of the buggy. 20" bar is the max width I can fit up front. Also what was on previously, so that is my main comparison. No previous complaints, but I'd rather not run one all the way across in front of the radiator.

Either of the ~4" round lights can be off to the sides and not blocking a bunch of the core. Similar ballpark price wise for a pair of rounds or a double row 20.
