How does it like highway speeds?

This is the only vid I've found that goes straight to the info/specs on these lights. Thank you very much!

i dont understand the point of the middle grommit styling. they dont flush mount, the stick out a bit because of that extra grommit lip. what is that for exactly? i got mine today from ebay and love them but im confused as to why theyre not flush

Thanx for the dirty laundry. Modern ones are claiming 9 watts. That is 750 milliamps of current at 12 volts for each LED. That is insane.

Thanks for the video!! I was wondering the same thing. I ordered a (9w)10pc on eBay, but they don’t look like 9w. 1w a pc looks more appropriate

Agreed.

Have you compare COB with SMD one?

I personally love these but, they are crap. Ive fitted them to my car and they last about 3 weeks before the lenses fall out or the water gets in the so called waterproof lights and corrodes the light chip. All of the ones i bought were from ebay as i dont seem to be able to find a decent branded source. Ive had the plain ones and the switchback type and trust me, if you want them to last longer than a month or so, dont bother because the build quality is trash for automotive use. Unless you live in a desert, these wont last very long..

What external AC to DC transformer would you recommend to power 3 of these 23mm LEDs?

These lights are cheap as fuck what did you think you will get

Welcome to china. Not news

3w chip ,with a resistor in the shaft

Yup, every lightbar ive bought ive torn apart just to confirm this nightmarish counterfit party.

I bought some to put in as my plate light im planing on using four two to replace in regular bulb. so will that last on one set of outlet connectors. I feel like they might burn out since the wires are really thin, or would two be fine fron on plate light outlet

if you but anything on ebay, never expeect more than 1/3 of that the seller is promising. btw, for the price, most of the led bars are worth it compared to other "BRAND" lights. baught 2 7" bars for 20$ that were almost as bright as a"brand" light that cost 150$ in a local shop. have now used them for 1 year with no issues yet :)

3030 it's basically just what LED manufactuers use to describe the LED package (dimensions of the LED 30mm x 30mm) not the model of the LEDs. What's really going on with cheap ebay light bars and LED products from china in general, is that 90% of the sellers use counterfeits or authentic but rejected Cree or Phillips LEDs on their products and inflated their specs 2-3 times, in fact many of these Light Bars have poor performance and reliability compared to higher price ones. My way of choosing a decent quality light bar would be looking at its price, optics and electronics, a decent quality 20" 3W Cree Light Bar would cost somewhere between $60-$120 to make (LEDs - $0.9 - $1.8 + $30-$50 housing), so the retail price would be $120-$240 (profits, overhead costs). Matching Optics are very important also, Light bar with custom optics that are optimised for a specific brand and model of LED has way better penetration and spread compare to those use generic off-the-shelf optics, dont get fooled by the fancy 4D 5D optics, most of them have bad beam pattern and the light scattered uncontrollably, causing dazzle and fatique.

i just got a 432 watt cree light bar off ebay what bs i got the same 3030 chips total garbage my 120 watt cree light bar out does the 432 watt tri row crap

I was always sceptical about 9W leds. thanks for saying the truth. It is very similar with sound system wattage. they claim 50, 100 or 200 W, but the true power is most probably 10 x less. 50% of consumed electricity becomes sound, and these boxes do not consume much electricity at all. All these sellers have to lie, because otherwise they could not sell. average users don't know how to check the power.

That's what you get for ordering a no name brand light bar

Just because an LED is rated for 3w doesn't mean running them cooler is a wrong thing to do.

Thank you for this quick video, I knew that the wattage claims were false but I needed proof. Now when I shop for them I'll disregard the power claims and pick up a set of the smaller 18mm.

are they water proof?

well you cand put themnin series because they are swamped for 12 volts 3 chips and a resistor in one package eachnine pulls about 0.1 amps so you can string a lot if then in a single bus wire, i recommend running multi core wire like that use on irrigation to feed differnt colors or sections that can be switched separately also use or 1 or 2 wire cores to carry ground so you dint have to mess with making that connection when mounting the studs

Can you run all of them in a continuous line off the battery and a switch or do you need any adaptors to drop the voltage, etc?

thanks! good unbiased review

I almost bought a "560 watt" 42" curved led light bar with "7w Cree chips" . Glad I watched your video. This was the same seller!

how long are the wires on the lights and it looks like they are wired in pairs

looks like the seller watched this video and disliked it. lol

wow ... while your ohms law was correct on amps to watts , but you really , REALLY failed on the output of the light bar ... anyone who knows about this , knows the light bar is drawing said 8.75 amps at 12 volts or 105 watts at 12 volts , that means how much power it is using , not the light output , light output is measured in Lumens ..... please educate yourself before regurgitating wrong info ... here ends the lesson for today

I bought a 300 watt 30" light bar item number 111855025653 from (arrowthea) shipped from California I believe the contact is from china due to only responding at 10 pm or just after (pacific time) after watching your video I dismantled mine to find out it has 3 watt chips not 5 watt chips as the add says, now they want me to send it back for refund, they probably figure the odd time they get caught and have to pay return shipping is less than the profit they make off everyone that doesn't notice, ebay should shut down their accounts for fraudulent practices, buyer beware if u bought one from here dismantle it and look at the circuit board mine had 12 leds and said 36w do the math and its 3 watt per led

False advertisement you can definitely Sue them for that!

just found this and thought i should weigh in. First, Philips as a company doesn't and has never directly developed or produced SMD LED's. BUT they did in 1999 begin a joint venture with Agilent Technologies which they called Lumileds. Now this company (a subsidiary of Philips) makes a wide range of high performance and consumer grade LED's, one of which is the 'Luxeon 3030 2D'. At this point i want to add i found all this information after about 15 minutes of looking into "philips LED bars". So yes it may not be using the advertised power but i would happily say that that light bar does in fact have a Lumiled SMD package used. A source of problem is more likey to be found in the constant current drivers required by the LED's and are most probably built to a price and in fact under power the LED's hence your lower observed value. Please please do some simple research next time before possibly ruining someone else's business.

I just bought a led light bar from ebay. It claimed to have 5w osram LEDs from Germany in it. But for $140 AUD, I didn't expect it to be real. I received it today, and immediately opened up the whole thing. I found "cree" printed all over the the board where the led chips are. The seller also claimed to give a 2 year warranty on the product, but there's absolutely no form or number with which to lodge a complaint. Only paper that came with it is working instructions. Ill see how it goes. It's a 22 inch bar. I don't hold high hopes. You get what you pay for on the internet.

vast amount of people never even measure the wattage. LED = Lies Every Day, Losers Except Details ... 1/3rd is common, many LED lights light bulbs etc . data from Cree XM-L2 cool white T6 280lm U2 300lm 1052lm max 1198lm fries Never use Aliexpress, alibaba, everbuying, gearbuy, gearbest, focalprice ... all huge criminal networks

what i have heard is that these arent very waterproof. And that its a matter of when, and not if they will go out :/.

Really? I don't think so, Actually my company just bought some leds from this shop "teammadegroup2011", but the quality seems is very good, no any problem till now. & the customer service is good, so I think that just a isolated case. anyway, thanks for your information.

I wished I saw this 2 weeks ago, got the same led bar from Ebay member Fulcat and already installed on my truck, it is extremely bright tho, but I will have to take it appart to see if its a 3030 chips. I will have to compare with a few guys with 30inches cree light bar before I make a decision... but the seller and ebay will know for sure if it's 3030 leds

Don't buy on eBay

I bought mine at Aliexpress from seller Ccarworld and it was just the same scrap of total 96 watt. It´s not even waterproof because there is no seal anywhere! I opened a dispute thru Aliexpress and after a week with bad excuses and lots and lots of mails back and forth, I finally got a full refund and I don´t even have to return it. Now I just have to look for something better that really works. It seems like all light bars with 5watt LED:s (Philips or Osram) are fake so I think I´m going for a light bar with 3watt LED:s (Cree), they seem to be more realistic.

would it be an issue to get your ebay username. I am having the same issue you had from the same seller. I would like to use your username as extra backing for when i claim this with ebay. if this isnt asking to much. Thank you for anyhelp you can provide. And thanks for the video, it was a great help.

ya I figured it was about time someone took one of these apart and aired the dirty laundry share this video around and it should result in a more honest product...

nice review man, just the info I was looking for. thanks for posting this.
