    What the hell are you blabbering about? Are you trying to distract people from your lack of knowledge and appear smart with long rambling off topic sentences? Because I tell you, most of us can spot BS when we see it.

    Lumens and light temperature are only half of the story. Anytime you put a tint on a halogen bulb, you're reducing light output. The other is the optics. Properly focused optics will give you a proper ratio of far distance and foreground lighting regardless of brightness, other than being too dim. LEDs and HIDs will not give properly focused optics in halogen housings.

    While I agree with need for focus , that has nothing to do with the argument stated that more wattage is no better . . . . Properly focused or not . .

    It's obvious you're not teachable anyway you already know everything so I'll leave before you make a mess and your head explodes and you say something you'll regret . . Didn't mean to step on your ego .

    Yes you May have the last word . . .

    Op, did you ever test light output with factory harness vs aftermarket? I'll probably go with the volsa 70 watts on factory harness to keep a healthy factor of safety, and because I'm to lazy to run new wiring, but was curious as to how much light output I would actually gain by upgrading the harness.

    With factory harness and bulbs vs stand-alone harness and Osram bulbs, yes. The results are in the headlight upgrade thread:
    https://www.tacomaworld.com/threads/the-ultimate-headlight-upgrade-not-led-or-hid.398066/

    But stock bulbs and factory wiring vs stock bulbs and stand-alone harness no. There were some voltage measurements buried in the thread that showed the harness increased voltage by 0.4-0.5v. While that sounds small it is a non-trivial amount when translated to bulb brightness.

    You won't have the glare issues with the projectors in your 17. But beam pattern may still be subpar.

    I have opt 7 in my 14 taco and the glare is ass and honestly the light out put is not that great compared to my old $50 HID hit. I had to do the glare mod to on the opt 7 to looks much better now. I left the opt7 in for now till they die....

    The Philips LEDs maintain cut-offs unlike Opt7s. However they appear to be designed for right hand drive vehicles, meaning they still are not the same as the OEM beam pattern, which is designed for left hand drive vehicles.

    I'd still recommended the halogen upgrade which outperforms both LEDs and maintains the correct beam pattern.

    Awesome write up! LEDs are a great lighting source but there is certainly still a lot of improvement needing done for LED headlights. There is a reason why vehicles offer headlight packages with standard halogen or LED/HID, its not just a simple bulb change that is costing you more for that option (which is what a lot of people who buy LED or HID kits assume).

    Owning my own shop I have had many customers bring me in HID kits saying "Dealers charge thousands for an option that I can get on ebay for $50" My friend, you have no idea how incorrect you are. This is a perfect visual to show people just how wrong they are. I will be using this write up A LOT, Thank you!

    Awesome comparison OP! This kind of stuff is great to show proof that reflector design and beam control is vital to lighting. If I didn't do a full HID retrofit, I would have very likely have done the Ultimate upgrade a long time ago had I known about it. That seems like a great option for better lighting from the headlights without doing a full retrofit.

    its a Toyota truck and that's all the modifications needed
    im thinking of doing the same, also im trying to find out the rated running hours of Voslas and the whiteness of them but I cannot find any infos or reviews about them.

    Welcome to TW!

    I’ve chatted with these guys in the past, they know their stuff.

    Note this thread is about putting LEDs in halogen reflectors, 2016+ trucks have projectors so you don’t have the glare issues of earlier trucks.

    That said the LEDs are still a bi-directional light source, and your halogen projectors are designed for an omnidirectional light source. So while it would “work” with the OEM projectors, you’d have a fuller beam pattern by running omnidirectional HIDs which are brighter than LEDs anyway. Headlight Revolution even has a page I believe that covers this. While not as ideal as HID projectors, your halogen projectors can run HIDs without the glare issue. In short HIDs will be a better performing option for you over LEDs. For best output look for something closer to the 4000k color temperature, and avoid the bluer light colors which are not good for night vision.

    No worries, nothing to be sorry about. I was just pointing out the lighting optic design difference means some of this thread does not apply to your lights.
