I decided to upgrade car and I bought this Magic Crystal H7 Low beam LED “bulb”.

It is declared as 100W and 25000 lumens 6500k cold white light. 300% Brightness comparing to Halogen bulb!

Diagram looks like this:



Testing subject is VW Passat B8(2015.) with reflector headlights:
Car lowest headlight settings:

Middle settings:

Highest low beam settings:

Tint Test: Left real cold white tinted On The Road Zoomie light

How it looks on my car:

What I can say? This is certainly not 6500k cold white tinted light as declared. It is probably 5000- K light natural white. It is green tinted(but in reality it does not look that green as on these pictures taken with phone auto settings).

Is it brighter than halogen? Yes! I see much better with this lights than with Philips White Vision H7 Halogen!
How much brighter? Well Phillips White Vision is probably the best H7 Halogen light bulb in a world and it is brighter than it! How much? Well it is certainly not 300% brighter. I would say it is maybe 20-40% brighter (really hard to tell) .
Does it have dark spots: NO! This bulb does not create any dark spots in reflector headlight beam. It produce nice and even beam as you can see on pictures!
Does it have declared values? No way of course LOL… This is probably 50W- 10000- lumen light bulb but nevertheless it is nice upgrade over Halogen H7.

Does it blinds other car drivers? After driving this for 1000km in night conditions I did not got even single blink from anyone. And I am driving in highest possible light position.

I did some redneck tests:
- First test was with IR thermal meter and this bulb tested on the table conditions. In such conditions bulb temperature will go from 80-90°C after 10-15minutes
- Second thermal test was done when I installed this bulbs into car reflector headlight and in such conditions temperature of bulb drastically drops(better heat sinking I guess when installed in reflector) so it goes from 45-65°C in about 30min test, steady non moving car.

What is good with this design?:
- Large 25mm DTP MCPCB on aluminum heatsink with active cooling
- This is basically like larger Flashlight Pill!

I will report how it goes or if anything gets broken. Because if everything will be ok be i plan to take H9 High beam bulbs also. So far so good…

P.S.
As you can see by bulb diagram this thing has modding potential! I don’t know which type of LED is used on this bulb but I am just wondering what if we swapp it with highest surface brightness emitter on market? Would that increase brightness of that Magic Crystal? I have opinion that high lumen LED in this setup is not giving full potential to this bulb.

Looks pretty good. In the low, middle, high low beam pictures, are you adjusting the headlight housing angle? I would say the highest setting looks too high, like it would be right in the eyes of motorists. The lack of people flashing you is not really a good measure of headlight angle.

Regarding upgrading the LED, the light emitting surface is determined by the frosted part of the glass tube, so a higher luminance LED will not necessarily help. You would want the highest output LED. But it’s also dependent on how well the light from the LED is collected into the tube (light collection efficiency).

Yes… Car has internal adjustment knob for adjusting light height… So you can see how it looks in position 1,2&3… I prefer highest settings on dry weather, and lowest one when it is raining or foggy weather.

I have 2 cars and we actually tried weather highest settings disturb… They really do not disturb of course. This is newer type of a car with modern reflector headlight. I would have to install the same light into my other car VW Golf MK4 which has old type of reflector headlight but I don’t have nerves for that currently… I just enjoy driving this one.

But as you can see this is not angry cool/cold white light either… Neither it is super strong LED light. Just about 20-40% better than Phillips WhiteVision bulb (which is the best H7 bulb in a world and about 40% brighter than regular halogen) but with much nicer tint than PWV which really does not have tint as suggested by Phillips WhiteVision name (it is somewhere at 4000k maybe even lower). So only thing what I can do now is time test for reliability of this LED bulb.

“higher luminance LED will not necessarily help”… Hmmm… Someone got to modd that and report Smile

We could actually use this as DiY reflector or aspherical flashlight host with active cooling by just removing Magic crystal above that and internal electronics if needed Wink

I have been using these for over two years with no issues on a Mazda CX-9.

Guys if you will order any type of car LED bulbs you got to have on your mind that you’ll probably need a rubber dust cover if you don’t want to mod your original one. So I will install this Magic Crystal bulb once when I receive “protective rubber dust covers” on slow boat from China Sad . Why I did not think on that when I ordered this LED bulb in a first place? Facepalm I don’t want to destroy my OEM rubber cup with sharpie so I will rather wait for freaking replacement rubber cup from China…

I feel need to quote myself on this…

You don’t need any kind of Rubber dust cover with these!

Magic Crystal is almost Original H7 halogen size(maybe 1 or 2mm higher) so it fitted perfectly in Passat B8 reflector headlights and under OEM protective rubber dust cover without any modification Thumbs Up

Is there a link for these magic crystal lights?

I’ve had varying degrees or success with LEDs. Standard reflectors tend to be harsh but in halogen projectors they’re great. But my wife’s current car a Ford cmax has standard reflectors and I’d love. To give these a shot.

I do not like to promote any seller but I bought from this Ali store: https://www.aliexpress.com/item/1005003258282631.html?spm=a2g0o.9042311....

This is still in testing phase in my car… If it will hold 2 months without issues I will order high beam H9 also from this store.

Note that you will see several types of Magic Crystal LED bulbs on aliexpress. I chosen this one because it has separated driver and connector cable. You see those separate driver and connector cables from my pics? There are also inline cable versions of Magic Crystal Bulbs out there and this one with separated driver and connector has big advantage over inline and that is easy manipulation.

Newer VW vehicles are notorious for Canbus issues when you install aftermarket stuff. I don’t have any Canbus issues with this one Thumbs Up

P.S.
I paid more Phillips WhiteVision regular Halogen bulbs than this one… With some discounts this Magic Crystal Bulb has cost me 40$

Please note they are not 100W 25 000 lumens bulbs as seller stated! These are around 50W 10 000 lumens bulbs!

What kind of led can pump out 10000 lumens at 50W?

I don’t know? Seller wrote that it has 25000 lumens at 100W. I estimated 10 000 and 50W but it is probably even less than that…

Someone should measure that.
