I think that sounds like an good way to look for lights on Ebay, you could buy an light meter to test the lumen, but than it's all about what distance they measured there lumen from. After buying some leds over the years I think the one I test from 2015 48w that is 39w is one of the best ones, it gives an awsome amount of light and are cheap. and I do love the 12w ones.

You can not test lumen with just a lightmeter. You are thinking about testing lux from a distance, but lux just tells you about how strong the light is in one point, no the total amount of light (lumen). For that you need to collect all the light in a sphere. The test you did with the camera is a good example how you could measure total amount of light if you have a lightmeter in the camera, or if you put a luxmeter instead of the camera and measure the reflected light from the wall. But you have to turn the garagelight of when you measure the light, or it will add to the result. You also have to remove the black banner on the wall because it wil absorb a lot of light in the focuspoint witch will reduce the amount of reflected light a lot from well focused lights. Thanks for a nice video. It's intresting to se witch products are worth buying. Would be great if you could put links to the lights yous tested. At least your favorites.

@@Larsema1 Good idea will put up some links for my favorites :) I'll stick with the watt test easy and with the photos from the camera you get an idea of the different amount of light. It's fun too see what the seller promise and what we get. I'm really curious to see what I get when the seller of the "400W" lights send me some new ones.

@@MiniMachines1 Thank you! I've also measured some of my working lights just like you. The wattage says a lot when comparing the cheaper range of lights, with the same kind of diodes/efficiensy. More expensive lights, like with real Cree diodes, is a little different. I'm thinking about building a box with white walls for measuring the amount of lux reflected from different lights. Not for an exact value of lumen, but to compare the lights with each other. Your wall and camera works too! Thanks for interesting videos! Excited to see a new video with the new 400W light later. And maby some new lights? ;)

@@Larsema1 yes will be some more testing are more lights on the way in the mail 👍 just need to install some also 😅 the valmet has got some new lights but still need more

The 12w and the big 48w are my favorites but check the size so you don't get the small ones trying to be 48w looks similar on the pictures

Mini Machines I found the 12w for 55 sek, think it’s the small ones.

@@NilsKall the 12w I think it's only one type and the price is right, but the 48w it's 2 sizes

@@MiniMachines1 Can I get the link for 12w and 48w ones please? Thank you

You're welcome!

Looked like you got a good amount of light from those small 12w lights. They are awsome since they are so easy to place and pull little power you can have a lot of them, light in all corners.

Mini Machines yes I really liked them, thanks for the tip!

Thanks

24V isn't likely to make them any brighter/increase wattage. The LEDS don't use anywhere near even 12V. There's a driver circuit inside them that has an input voltage of between 10-32V but has a constant say 6V output. Obviously increasing voltage will reduce the input current but the wattage shouldn't really change.

@@deezelfairy got ya thanks

That's awsome 😀

I will for sure make some fun videos with the ranch truck (old pajero) this winter, and maybe the new one to 😁 kzfaq.info/get/bejne/obqGhZaQ2uCqmIU.html

Also, I noticed you locking the exposure with camera 👍

Yes else it would be a useless picture😀

@@MiniMachines1 👍

@@MiniMachines1 many other reviews make in in AE and the camera adjusts settings, and eventually 4" bar and 50" bar look the same 😳😂

@@MiniMachines1 I know that you know that 🤔😂

Yes sadly that's how it is for most lamps, I ordered some nice nano leds that was suppose to be 9w measured them to 3w, thats a big different in light output.

Not that I know of, the cheap ones give a lot of light but it's more close to the car not where you would like it with an high beam far from the car. You get so much light in close to the car with them so it's hard to se the light that is far from the car. But I've only tested a few so might be some cheap that works. Best so far is xenon extra lights, but some cheap that's for halogen and install a xenon kit in them that gives you great high beam lights, but dosen't look good at all cars...

They're all basically the same wattage. Get whatever is cheapest.

Errmm... Use a 24V power source? 😂 It's not going to make them brighter though, the LEDs use less than 12V anyway, there's a driver circuit built into them to reduce the voltage internally to the voltage required. The 32V limit is just the driver circuits maximum input voltage.

Same ones that I installed on the bobcat?

No, Arbetsbelysning nr 38-788. 24w Gen 11. 👍

Good idea thanks 😀

If the wattage is near true it's 45amps than the cable is way too small, but likely it's not that many watts

@@MiniMachines1 I will measure current first. Then decide about wireing. Better this way.

@@MiniMachines1 it showed 10 amps lol, I have to verify with another device coz I am shocked xD

So about 130 watts than you can safely use your 2,5 wire if it's not too long😊

Oh that is so many years ago that I have no idea 😕 I think I bought it from ebay

@@MiniMachines1 i want to buy that which is on 09:45 in your video 🥺.. i saw on ali express & in amozon they have fake 48W led bar lights which is in real only 11 to 12W with plastich heat shrink.. If its possible can you please search that led i want to buy i am from Saudi Arabia 🇸🇦

Thanks 😊 links for the lights I use and like the most are in the description 👍

@@MiniMachines1 I can't see them.

are they gone? check the comments section

Never seen ledbars for 220v but you need a big inverter than and you get a new source for error.

I just got in 10 lamps from china (Alibaba) they where suppose to be 36w measured them to 2watt, I made my complain but as long as you could se light from them it was no money back☹

@@MiniMachines1 sorry to hear that. I usually buy from Aliexpress, which is (or was) quite good with disputes. FYI

@@MiniMachines1 sorry to hear that 😡 that doubt is always on my mind and prevents me buying these lights

@@MiniMachines1 also, precious LED bulb replacements "failed" very quickly on my Defender. So, I eventually I turned to "classic" bulbs, which seem to last better 🙄

@@overnighter I also thought it was a safe system since the seller dosent get there money before I've received the product, but here alibaba woted with the seller since it was light from the led's🙄

Hei og takk for det, Danmark er nok mitt favoritt land å feriere i trives veldig godt der. Ja er klar over at watt ikke er rette måten å måle lysstyrke på, men det var beste måten å sjekke om det selger påstår i annonsen sin stemmer, å sjekke om selger oppgir rett lumen er vanskeligere for da må man vite litt mer om hvordan dem måler lumen som dem oppgir i annonsen. Mens watt er enkelt å måle :)

That's true, but I measured the watt against the watt the seller said it would have, so it's apples against apples 😉

Measuring Lumen is cumbersome and expensive to do. One test that is a bit easier is to measure lux at a specific distance. LED bars often have at least two numbers 1 lux distance, and 0,25 Lux distance. Of course, that doesn't measure the amount of light, just only the intensity at one spot but it is still a pretty easy comparable thing. Most proper manufacturers nowadays write theoretical Lumens and actual Lumens where the theoretical is just the LED bead stated Lumen times the number of beads used in light. Measuring Lux at distance straight from the light AND measuring Lux at fixed angles (30, 60, 90 perhaps) and distances would be a good way to get a comparison of the amount of light one actually can use from a LED light since it depends on what purpose the light has, a working light should give most light on a wide angle but not necessarily very far away, etc.

Do you think you'rs are closer to 400w seeing the other ones that have over 100w in the video?

@@MiniMachines1 they are def closer too 100w bought them off ebay they were like nao 7 inch led baror something

IMO it's really hard to say "same ones" with certainty since manufacturers in this category copy/steal from each other wildly. A LED bar that looks identical to another can have different LED beads and/or LED driver electronics. Even bad soldering can influence light output so not only components but also the manufacturing process can make a big difference, especially when we go to the high-power ones. Even the exact same Ebay-listing can contain a new batch of lights that can be better or worse than earlier batches. It's a lottery, I have won and lost thru the years buying Ebay/Amazon/Ali Express lights. My next light for the car will probably be an X-Vision D MAXX from a genuine Swedish seller (I live in the dark Värmland forests 😁) @Mini Machines: great video 👍 I would love to see a new video with some Lux measurements, it doesn't have to be an expensive, perfectly calibrated Lux meter as long as you use the same one for all tests, the relative numbers are the important ones in my book.

Yes but at only 5w I guess it don't need much heat displacement 😅

That's true, I always sort by price with shipping lowest, as you say same product different prices
