Hey guys,
These H4 LED globes that are advertised on ebay says they are H4.
http://www.ebay.com.au/itm/12V-H4-80...3D311406585692
So how come they are not suitable for headlights? It says they are suitable for Signal, Turn, Brake, Parking, Tail, DRL and Fog lights.
But, no mention about headlights? But, they are H4, which is the standard for headlights, right? Not for Signal, Turn, Brake, Parking, Tail, DRL and Fog lights??!!
2000 lumen brightness sounds ok?!
What am I missing here?
Thanx.
I suspect that it is due to the difference in the source of the light.
H4 headlights rely on a point source of the light from the small filament for the reflectors to work properly and the LED versions have a wide spread source of their light - being sourced from many individual LEDs over a relatively large area. The design of the reflector is critical in producing the beam.
I have played with some H11 LED bulbs and even though they produce a similar amount of light to incandescent bulbs, they do not produce a significant beam from the reflector housing.
What about these.

Yeah, I've noticed them. Price kinda indicated they are probably not worth the trouble. It has a bulky bubble base and LED point of source appears to be quite the same as those el cheapo ebay ones I've posted in the OP.Quote:

H4 LED headlights will cost about $90 plus for a pair, My mate is happy with his.
Im not convinced the hi beam is all it should be, but a nice white light thats for sure.
They come with fans fitted to cool the led drivers.
So, LED globes without fans will fail?Quote:

Not my cup of tea TBH
I'm guessing Ebay el cheapo LED H4 globes as in the OP is advertised without the mention of "headlights", 'cos they are not legal in Australia?!Quote:

runs a set , not sure about Mudski he has the led driving lghts
So you can still fit H4 LEDs to factory reflector housing?? or do adjustments need to be made??Quote:

I think he was saying not to bother with them.Quote:

Okie doks, so really not worth it it seems when it comes to price/efficacy as you were saying. Guess i'll be looking at another option!Quote:

I'm sure they are ok(the $90 ones). But, bit too bulky IMO, 'cos of they have to have a built in fan unit at the back of the globe to cool it. And that bit sticks out of the back of the head lamp, which can be an issue(in my case, it will be 'cos there's not much room behind the head lamp).
Instead of using LED for head lamps, I prefer the idea of using them on driving lights now.

I looked into this some months ago and at the time there were no aftermarket ADR approved LED head lights available in Australia. With all the 4WDs being pulled over and checked of late, (especially if you are towing a large off road caravan) I wanted to make sure I am fully legal so I have gone to a upgraded H4 ADR approved globe (non LED).
Just my two bobs worth.
Good little read here on the different types of headlights
http://www.caradvice.com.au/278125/h...v-led-v-laser/
Yep - exactly the issues I came up against some time ago. I converted my lights to HID (a lot of mucking around as you have to put your headlights in an oven to be able to separate the glass from the backing) and then drill holes in the reflector and install the projector inside the light, rewire the whole thing, find somewhere to mount the inverters and the control unit, etc. The result was a bit more light - but an unroadworthy Patrol. When one of the projectors fell apart due to off road work I dithched the entire expensive mess and went back to new headlights with legal upgraded globes.Quote:

You can use 100w globes to improve the brightness, as oppose to 60w standard h4 globe, but may need to wire up a
relay to be able to handle the extra current.
For extra light on long country stretches, you can simply install drive lights and wire them up with the high beam with a relay.
I upgraded to factory 60w alternator to a 110w one, using an EF Falcon alternator to handle the extra current(if necessary).
All in all, it's been a cheap upgrade with good results.
On the money there @dom14. Previous owner of mine put in 100+/55s, which turned the H4 plug to charcoal and the wiring into tortured red melted messes. He must've bumped up the fuse too. Not sure how close I came to car fire... Back to standard draw high outputs now.Quote:

Good read mate. Thanx.Quote:

This looks like a pretty good deal to experiment with. Loom upgrade is a definite need for this.
http://www.ebay.com.au/itm/H4-Haloge...QAAOSwKrxUaXi4
just because it draws more current doesn't mean it actually brighter. and if you have plastic reflectors high wattage globes even with a loom upgrade will melt the actual reflector.
They come with a loom don't they? So can they pretty much go straight in? Misso bought me a pair of JW speaker and was gunna return them but still in 2 minds whether to give them a go...Quote:

Yeah, the thought has crossed my mind.Quote:

I was hoping the claim of 6000k brightness is real.
I'm wondering whether anyone's tried these higher wattage globes in their conventional lenses, successfully(without cooking the lens)??!!!
i'm running the blue plus 90 http://www.narva.com.au/products/bro...ormance-globes
Hi @dom14.
Can't remember the wattage. May have been the one you quoted, but low beam was atrocious, so was probably xxx/55.
On the 6000k "brightness" - lumens are your measure, not Kelvin. K is the theoretical colour of light produced by a matt black (insert substance that I've forgotten here) at that temp. More a measure of colour than brightness.
FWIW - I've changed our non-patrol back from the Philips 5000Ks i put in as they were actually worse for brightness than the Narva Plus120s in there now, which are much further down the colour-temp scale, but must be higher lumens. I have the benefit of H4s - not sure what's available with sealed beams.
I use these which work really well, I'm very happy with them. Still using the stock loom, apparently will get better output if I upgrade but it's good enough for me.

By stock loom, did you mean the factory loom without relays?!Quote:

Where did you get the lenses from? 'Cos the stock headlamps are sealed ones.
I'm guessing they are high temp resistant?
You can do the conversion by buying the raw material from Jcar electronics. The conduit, relay, higher amp wires & connectors shouldn't cost much. We only have to wire it up between the battery & headlamps, don't we?
I reckon it can be done fairly quickly if we have the raw material ready.
I already have all the bits and pieces in a box, except globes. :) (I'm waiting for them to arrive).
Of course, a better, high temp resistance lens make a real difference I think.
I'm bit concerned whether the higher wattage globes will cook the lenses.
I'm starting with 100w ones, and see how it goes.
Yeah, but those are 24v ones. Good for 24v diesel Patrols.Quote:

Yeah factory loom, seems to be handling it fine. They draw the same amp's as normal globes.Quote:

Ok, cool. I've been warned about factory loom getting cooked & the switch as well. That's why I've been avoiding globes any brighter on the factory setting.Quote:

I had an ex NT government GQ many years ago, when it blew a bulb I found it had 90/140w bulbs, sealed beams had been replaced with H4 reflectors & upgraded loom with 1 relay for low beam & 2x for high beam. They were illegal I know, but when you dipped your lights you could still see. I also found that if you used the high beams of rough roads or off road the bulbs would blow, the filaments must be more fragile, I drove home one night with one low beam & no high beam.

Yeah, I carry normal 60W spares all the time in the car.Quote:

Do you need to have three relays? Probably a better insurance on high amps?
Why are they illegal(90/140w)??!! If you adjust the low/high beam direction according to the brightness of the globes, it should be ok with the law, you reckon?!!
