cree XHP70 H4 60w 8000L bulbs: real deal or false advertising

Hi guys

I am looking to upgrade my toyota land cruiser 90 series headlights from halogen to leds. I dont want to use HID as they take long to warm up and usually have issues with ballasts

So, i crossed with this bulbs and they claim to use real xhp70 chips (2 chips per bulb) which i have seen in some flashlights. I have a zebrealight sc63 and uses xhp50 chip and man, that little fella lights up big time! so, if those bulbs uses xhp70 they must do a pretty good job

here is the link:
http://www.ebay.com/itm/112156204396

they claim:
Working Power:60W (32W per chip x 2 chips per bulb)
Light Source: CREE XHP70 CHIPS
Operating Voltage: 12-24V DC
Color Temperature: 6000K
Lumen: 8044Lm per bulb (4022Lm x 2 chips per bulb)
Lumen/W: 150Lm/W

What do you think? for that price can they be real xhp70 chips or this is false advertising

Thanks for your help

I don’t see why they couldn’t produce that amount of light. An xhp-70 is rated for 4k lumens at around 4A so it stands to reason they could get that on these units. My only concern is how are they planning on cooling that? That’s a lot of light and a lot of heat!

aparently they use some copper to dissipate heat. I have seen a lot of led bulbs with this heat disipation system and seems to do the job. Other bulbs use little fans.

My biggest concern is the chips not being authentic cree leds. But if they do, those bulbs must be something to consider

Sure looks like XHP70 in the pictures, I would believe the emitter claim. The lumens are more suspect, because 4022 is exactly the number pulled from Cree’s spec sheet. That tells me they probably didn’t actually measure it, just stating what Cree claims. It’s possible that they are still making 8000 lumens, the XHP70 is capable of it, but there’s no way to know for sure. An XHP70 costs about $10-12 individually, way less in bulk. I don’t think the price tells us either way. Those things will get smoking hot though. I don’t think there’s enough there to deal with the heat very well, but headlights are made to be hot anyways.

6000k sounds absolutely awful for headlights though, and illegal in many states. Not sure about international laws.

Even if the headlight housing can take the heat, the emitter may not last long in those conditions.

Also, I’ve heard that LED replacement bulbs are a bad idea for car headlights because the headlight reflector is designed around a specific light source and changing the bulb could screw up the beam throw. I’m not sure if perhaps these bulbs take that into account, but I thought it worth bringing up.

Yes, good points. I have also heard that LED retrofits don’t throw as far or have irregular beam patterns.

Now knowing the price of xhp70 chips it may be real as they buy them by bulk for sure.

Now i have the heat concern in mind

Here in my country (Venezuela) we don´t have regulations on that (as in many other important issues, for our bad luck)

Good point. But this must happen with HID too right? i mean, is another source of light different than halogens. But yes, i also had read about irregularity on the beam pattern. but recently a friend put some led bulbs on a toyota hilux and they shoot a very intense and crisp white very similar to a 35w hid 6000k

But, as a good big mouth guy that i am Big Smile the bigger the better, i dont want those bulbs, instead i want the xhp70 that sure are brighter Evil

Yes, it happens with HID too. HID in a original reflector will blind oncoming drivers, and an LED could do the same. YOu may need to adjust your headlights to point down more if you use these.

The beam pattern depends on each reflector. In some cars LEDs will look awful, in some cars they will look great. just depends.

Yes, and we actually did that. We set up the truck in front of a wall and directed the lights a bit lower. than i tried standing in front of the truck and did not get blind (not too much)

I put LED headlights (H4) in my bike (Kawi c14) and they are amazing! far brighter than my old ones. was worried about the light pattern but they are fine and have not had any problem blinding oncoming traffic.

Actually here is a video of a guy who put not one but TWO h4 xhp70 on his bike. The light pattern look great. I would love to understand what he says but i dont

They look good, the Kawasaki is a dual headlight, just really impressed with them!

He never shows the light pattern. You need a wall or something to see the beam shape. It may be totally screwed up.

Here is what LED bulbs look like in my bike that came with H4 bulbs. Notice the sharp cutoff line. That’s what you want.
