The Magic Crytal LED Car Bulb review!

That is rather old thread to be honest. Car LED bulb improved greatly since that time (2017.).

We all know that Chinese exaggerate at numbers… I did not took that because some Chinese convinced me that his bulb has 30 000 lumens! But description sells stuff especially if you have great competition and uneducated costumers(80% of them) . Same like 18650 batteries stated at 10000mah. If you don’t know the truth behind false advertising would you chose 10000mah or some 30Q with only 3000mah? :laughing:

I’ve done more than thousand of modded lights for sale so I have my own logic on picking up things with intentional but accidental discoveries that I incorporate in my builds… This choice has potential in my eyes so I really don’t care how other people see that…

And photos and video from that link looks very good IMHO. If you think opposite that is also OK. Depends on angle, camera, weather…
No one should judge something if he did not try that by himself.

Weather I will dazzle someone out or not we’ll see in regular traffic test. If light will be brighter than halogen, without any side effect that will disturb other drivers they will stay on a car if not I have another plan for them :wink:

Anyone remember that LED replacement which had individual adjustments for “filament” placement? Ie, you could twist, slide, etc., the beam holding the emitters, to try to get it placed just right for best focus.

Carries forward to 2020 toward the end….lots of good relevant info, though, and that survives the test of model years. :slight_smile:

I had the one that could be only twisted.
It made a difference (naturally) in which position it was .

Well, they're installed and I even went ahead and reconditioned the plastic headlight housings at the same time. These lights are ok but definitely nothing to get excited about. Better than the stock halogens but honestly not much better than the 40 dollar Auxito cheapies from Amazon that they replaced.

This is in a 2011 Kia Soul. The $60 HID's I threw in my 2000 Corvette provide better visibility than these. Maybe it's the housing design. I don't know.

Is the beam evenly spread across the road without dead spaces?

I ran HID low beams in my 2002 Subaru Legacy GT for 10 years until it was stolen and totaled. The key is proper alignment or folks will flash you and you’ll be a nuisance or danger on the road. No LED or HID ‘kit’ is a true retrofit or drop-in, even with projectors. Beams must be adjusted properly after an install. Plus, the type of housing makes a difference. Although conversion kits may be off-road use only here in the US you can get by using them if you do it right.

The beam pattern from the GTR's is better than the beam pattern from the Auxito's. Yes, definitely more evenly spread, but not perfect. But barely brighter than the Auxitos. Most importantly, more light on the ground while the Auxito's were basically impossible to aim properly. With the Auxito, pick which road sign you want to point each one at. My aftermarket HID's in my Corvette are great though. Decent beam pattern and super bright. Mine has separate high and low beam bulbs. I only swapped out the low beams to HID. My HID low beams are much brighter than my high beams.

OMG :expressionless: hope you had full insurance…

Could you try your new LED lights in Corvette?

The Kia lights are 9003 and the Vette low beams are 9006. The electrical connectors are different.

I changed topic name since I ordered mentioned “Magic Crystal LED Car Bulb!

It looks like this:

For now I refuse to put that in a car! Why?

I need to discuss something with you guys!

I did test with car battery fitted with charger giving 14V of output.

This Magic Crystal is polarity sensitive so you must watch on ±.
Ok… I Connected this and wow! It really gives enormous bright light which seems does not have 6500 tint(I would say somewhere at 5800k).

I did 10 minutes test with IR thermometer . In first minute light was at 65°C and rising in second minute 75°C and rising I came back after 5 minutes temperature 85°C and rising! After 10 minutes it seems to be settled at 89-90°C

One more thing… After that I disconnected charger from car battery and now we have 12,4V of battery charge… When I did this temperature fell to about 85°C and it seems that brightness dropped slightly.

Yeah… I know… This is redneck test but from that test I found out following:

- Driver is unregulated and it does not produce any heat at all?(What is this? Some kind of FET inside?)

  • Bulb with aluminum heatsink and working active cooler heats up to 90°C! Or 194 F! (It seems that small cooler propeller is not able to cool this thing properly?

So I really need discussion here…

Is that kind of heat normal for car LED bulb? Or better to say how much heat does Halogen Bulb produce comparing to LED? (with this data we could compare)

I am afraid to put something that hot in my car… Just imagine that lets say that small cooler fails to work! Temperature will go to 100°C for sure!
This can’t be safe right?

P.S.
You see that I tried “Magic Crystal” in flashlight reflector :laughing: :person_facepalming:
It throws ugly beam and it is impossible to properly center it…

Sorry on bad pics. My rugged phone(BV9500) can’t do any better than that.

This magic crystal is an interesting design. I guess the shaft acts like a fiber optic, containing the light. Then the top is frosted which scatters the light and becomes the light source. This allows the LED to be placed at the bottom where it can be better cooled.

Luminarium, my guess is that 100C is not that hot compared to other things under a car’s hood, but I guess it could affect any plastic is in contact with.

Let’s not forget that a 50W halogen bulb can act as an IR heater to desolder goodies on pc boards.

EasyB and Lightbringer,

Would you go and install this into your car? Remember it is 90 +°C (it is Winter time now but in Summer days it is expected to be more than that) ! Do you think it can melt my car reflector headlight? Or rubber sealing cap? I am very worried :frowning:

This Magic Crystal Bulb has approx 25mm DTP board above aluminum anodized cooling fan. Or better to say DTP lies directly on top of the cooling fan on perfectly flat anodized surface(something like larger diameter Jacob A60 :slight_smile: ). That 3 screws are going through DTP MCPCB and they firmly press it to the heatsink surface. I unscrewed those 3 screws and I could see DTP bottom and silver thermal paste beneath it. I did not tried to dismantle it completely yet…

But this is (beside driver and mentioned magic crystal above DTP) basically flashlight type of Bulb design.

That for I don’t get how darn thing can be so hot! My lights with 5A current draw are hot but they never surpass 65°C without active cooling! So why this is so freaking hot with aluminum heatsink and active fan cooling? It is stated that it has only 5A current draw?

I wouldn’t, for the same reason that I wouldn’t be able to stick in those bulbs without having to forgo the dust-sealing caps.

I wouldn’t want splashes and drips getting into the reflector area and permanently staining/ruining it. At least the cap is one more level of protection.

There are protective rubber headlight cups (universal and even the aftermarket one that can replace OEM part all over aliexpress).

One example of universal:

Edit:

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 :frowning: . Why I did not think on that when I ordered this LED bulb in a first place? :person_facepalming:

I don’t want to destroy my OEM rubber cup with sharpie so I will rather wait for freaking replacement rubber cup from China…

Yes. Daniel Stern gives a lot of useful info there. But it seems it is bit outdated(that site is created at 2003.?) since I don’t see any automotive LED info there.

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).
