Mr.Nitemare, before and after each bulb test photos can be found on G8 board showing the cut off line being measured. It's not just me installing these in the G8 and posting pics, many members have done so. I would invite you to go there and see these pictures for yourself
I did mine first, my wife liked how it lit up the road so well so I did hers next, she drives a Mazda CX5 with projector headlights and her truck has LED'S installed in her fog lights as well. My kids wanted theirs done, they were next. My oldest daughters BF did his after that. My youngest daughter has told me her BF just did his Jeep but I have not seen it in person yet. My friend Derekprz from G8 board did his (his pics are available to view as well on the above named site) after him came many more G8 owners, some didn't care for them while others love them. I think it all comes down to personal preference.
I'm really confused as to why you're calling me a lyer, do I know you sir? Have you been given some bad or false information from me that I do not know about? Have I wronged you or caused you any undue problems? If so I do apologize to you sir and would only ask of you what I did to deserve such a label and treatment from you. But what you have done is to provide not a very good impression of yourself towards a new member I must say.
Yes all LED lights need air to cool them this is very true but in my testing using a hand held laser temperature gauge I only noticed an increase in the temperature of the headlamp housing and the air inside using an independent AIT sensor of no more then 42 degrees on a 90 degree day running the headlights for 6 hours. The heat generated by the LED headlights never exceeded 42 degrees hotter then an HID or halogen bulb installed in the exact same housing. The volume of air contained inside the headlight housing proved more then enough to keep the LED bulbs well within their normal operating temperature range specified by their manufacturer. I would greatly like to see the results of your tests that you conducted as to the temperature increase of the LED, the housings and the air inside the headlamp during your tests.
Further if you install a bulb incorrectly inside a projector housing of course it will effect the cut off line, it's silly to think it wouldn't. Which is why you always make sure you buy the correct bulb and install it properly.
Yes a shadow will be cast but if you put your finger or a pencil in front of your headlight how noticeable is that shadow on the road at say 50 feet? 100 feet? During driving neither I nor any of the other people using the OPT7 LED headlight have ever noticed or complained about it causing any problems. Well none that I know of that is, I can not speak for everyone who has installed this brand of bulb.
As a note all tests done by me were done using the stock GM headlight housings found on my 2009.5 Pontiac G8 GT. I can not tell you weather or not the volume of air inside a Dodge Charger headlamp would provide equal, better or worse cooling as I have not tested them nor compared their internal volume to that of the G8. My tests were conducted in my driveway during the day as to not have the cooling effect of the night.
VLED's are one of the brands I would advise not using as they do not take into account the loss of lumins due to the increase in the temperature of their LED bulbs. You must find brands that specify this drop in lumins so you can get an accurate comparison. LED loose lumins when they heat up, heat is a by product of them being turned on. The hear sink and it's ability to cool the LED as well as the quality of the LED itself matters greatly. Which is why I #1 said don't buy cheap and #2 gave a name brand I know to work well. As to the little control box they fit inside the housings of the cars I've done as they are not that big. Maybe an inch wide by a couple inches long by a half inch thick. If you leave the dust covers off you get lots of condensation inside the headlamp housing, or at least this is what I found after only 1 week without them. It was then that I did all my testing because I needed to use the dust caps against the manufacturer recommendations.
It's quite clear you do not like LED bulbs and again this is your personal preference and I would certainly never tell you you are wrong for liking what you do.
