LED Headlights

Hi all,

I hope this will be a quick one. LED or HID headlights must have self leveling and light washers to pass IVA unless the output is below 2000 lumens.

Is this 2000 lumens per headlight or 2000 lumens for both?
I'm looking into headlights at the moment and Dominators are currently winning due to cost, size and they'll get through IVA but I've found Denali LED light pods which kick out 1095 lumens per light and they're tiny. Obviously if this is 2000 lumens for both lights, these fall just outside of what is permitted.

Thanks,

The manual, note 4 under section 25, says total output. I'd take that to mean both. They're not going to measure it though, it says you must provide evidence.

I don't know a lot about the Denali's, but so far as I'm aware they don't have a different main beam to dip, they simply have one beam pattern & dim the light for dip beam, I'm also not clear on whether you have to dim to half power (which would be fairly useless) or if the power can be controlled between half & full intensity. If the above is the case them one, you'd be either sacrificing main beam light distribution to have a correct dip beam, or you'd have an incorrect dip beam pattern - either way I can't see them passing IVA

Reading between the lines I think they are intended more as a spot light than as a headlamp replacement?

Thanks for the replies.
I think you are right, these do look like they can only adjust the intensity rather than the actual light spread so dip and full probably wouldn't comply.
It looks like the Dominators are still winning at the moment then. I've sent an email over to Furore about these and the Photons (Thanks Russ).

It would be nice to have confirmation to my original question as it does seem open to interpretation whether the 2000 lumen rule apply to single headlight or combined light output of both or 4 if you decide to have that many. If I do get confirmation of this, I'll update the thread in case anybody asks the same question in the future.

I note that the 1095 lumen is their marketing 'Raw Lumen' figure.
ie without any losses.
real output will never be nearly as high as that theoretical max.

Are they and do they need to be E marked to be compliant with Construction and Use reg?

This is an interesting question as I always thought they had to be E marked, but recently I read the C&U and don't think it's that clear cut. And my OEM toyota headlights aren't E or BSI marked either. One of the biggest aftermarket sellers for my Toyota sells unmarked headlamps and outright states it's a misinterpretation of the law. I'm still unsure!
