Why would you assume such nonsense.
A lense gives no cares how the light is given. As long as the light eminates from the correct location. HIDs are hot so as long as its glass but HIDs are junk anyways. Like the zip disk.
I swear most people have no clue what is what when it comes to this stuff just like back when it came out in the 2000s so much made up bs. Please stop spreading bad info about this.
Actually,
@Nuje is right about this, and you are not. So would YOU please stop spreading this nonsense.
Those Depo projectors are NOT designed for HID bulbs. They are only designed for halogen. It even says it on the headlight.
A lens design absolutely determines the output of the light. As well as how the projector bowl is designed. You need to go research your lens refraction principals. You try and run HID's in those Depo lights you're likely going to burn the projector bowls over time and your output will go to crap. As long as they are glass? Every projector lens is glass there bud, the reflector isn't glass though. Halogen projector bowls aren't designed to take the heat of the HIDs, hence why you have to use projectors designed for HID bulbs. Plus, even though they are a projector, they throw a ton of scattered light above the cutoff (Depo with HID's). How do I know? I've tested them.
As long as the light comes from the same location? Ha! Come on Mr. know it all, you should know better than that, lighting master! The location of the light is only PART of the equation. LED's do not, and will not ever throw light the same way as a halogen, or and HID bulb, no matter how they are designed. It's not the same type of light, it's not produced the same way. You can try and mimic filament light output with LED's but it will never match. It doesn't matter if you put LED's all around 360* and match the location of the filament. There is much more to it than that.
Hence, why when you try to drop in ANY led to a reflector housing, they are garbage. Except for the NEW OEM LED's that come with vehicles. They actually have a reflector that is designed for the LED. That's the key. If you want the output to have the same cutoff characteristics that are DOT legal to halogens, the reflector has to be engineered to reflect the LED light to eliminate hotspots, ensure cutoff characteristics, and eliminate scattered light. LED drop-ins in a standard reflector housing not engineered and designed to do the above are just going to throw light everywhere. Take your garbage LED's and put them in 3 different housings and they will show 3 different outputs, guaranteed. None of them will produce legal light output. They will do the same thing in a projector that's designed for HID's, or halogens for that matter.
HID bulbs produce light output the same way, every time, consistently. That's why you can buy a projector that's engineered for an HID bulb and they work perfectly. You are not dealing with inconsistent and different light output like your Amazon LED's. Ever see a retrofit projector that says it's designed to work with drop in LED's? Nope. Because you can't design a projector bowl that will reflect the light of every LED drop in consistently. If they could and it was worth the R&D time and money, they'd be available. Cheap drop in LED's are a money grab and that's it. The ONLY LED projectors even for sale on the market for retrofit have the LED integral to the projector. The bowl and lens are designed specifically for that LED and that LED only and you can't replace the LED. They are very expensive even for what they are and a HID with a projector still is superior to the LED integral projectors on the market. As a retrofitter, it doesn't even make sense to run these vs an HID projector setup. If one fails, you have to split the headlight again and replace the entire projector unit rather than just replace the bulb. That is a royal PITA if you've done your retrofit correctly in the first place.
So, my suggestion, is you go back to the books and stop spreading YOUR ignorance about this subject. Stick to what you know and help out where you can, but your lack of knowledge on this subject is VERY apparent. I want to make sure those that are interested in the subject have the facts rather than you trying to just argue and defend your stance, which is just flat out wrong.
