Another LED/Halogen Comparison

I got these LED H4 bulbs from @FirstGenVol

He installed them, but was unhappy with the quality of light, so offered them up on the forum for cheap... so I decided to give them a try. I'm not sure of the brand or where they came from; the drivers just say "LED Headlight" or something like that. So certainly a Chinese knockoff of some kind. I promised him I'd post up some comparison pics, so here they are.

The light output seems to be higher. That's hard to tell from the pics because they were taken with my cell phone, which doesn't allow manual exposer, so the phone compensates for the added brightness. There seems to be a little more "scatter" outside the primary beam, mostly on the ground, but the cut-off is good, and they don't seem to have excessive glare. You can see from the pics that the cut-off is as good as the halogen. I haven't been flashed by any oncoming traffic.

I have to say I'm quite pleased with them. My headlight fixures are aftermarket TYC brand from Rock Auto -- maybe that accounts for the differing experiences between myself and @FirstGenVol ? I don't know.

Halogen
LED

 

The LEDs are definitely looking brighter, though it also looks like they aren't cutoff as clearly for oncoming traffic. Doesn't look like it's terribly bad above the halogen cutoff, but without being on the receiving end and from these pics it is hard to tell. I hope they work well for you and don't bother any oncoming drivers.

 

sure they're adjusted?

Some, just some, LEDs have the ability to rotate to allow for that beam we're seeing at a cock-eyed angle (left is lower then travels upwards toward right in pics). Mine do and they're nice and Wide beams as a result.

but overall, sure LEDs have more output and better color for us carbon life forms to see with, Luck on longevity.

 

Yes, they're adjusted properly with the "shield" at the bottom. To me, the halogen (first pic) looks more cock-eyed... no?

 

Those are the Katana brand. Glad you like them!

 

I have these same Katanas LED ($49) in my aftermarket Akkonn housings. They work very well for the price of about $10 more than Silverstar filament crap. I went through this same light test comparison last year and was impressed.

A year and a half of driving and zero flash backs. I do get people staring at my lights in both daylight and night time. Its as if they are mesmerized somehow. Never had this happen with my other bulbs. Strange.

Note that these headlight bulbs along with some righteous LED Fog Bulbs will put a tingle in some special places.
