What argument am I making?
In this thread, you've said the Philips LED automotive bulbs are inferior and yours are superior. When pressed for details on how you know your bulbs work acceptably, you said you're basing it on customers' reactions.
(7443 dim functon) More like 40
The spec for the 7443 dim function is 35 lumens +/- 20% (that is 28 to 42 lumens) at 13.5v.
I made it clear that it was a work in progress, and that it was too bright, did I not?
Fair enough -- I was assuming (see what happens when we assume!) that you were showing something ready or almost ready for prime time.
Just the only report I had easily accessible.
OK, that makes good enough sense -- though data of this nature for bulbs that
are ready for prime time would go a long way towards silencing objections like mine.
There is no practical reason to even make a white 7443 LED replacement.
I can think of practical reasons to make a white 7443 LED bulb. Apparently so can people at your company, because you offer it for sale -- I just checked, and your website says it's in stock for immediate shipment. Are those the bulbs that are a little (like 10x) too bright on the dim function, and are still under development? Or are they some other 7443 white LED?
What specific standard are you referring to?
I already mentioned them specifically in post 22 of this thread.
Are you just talking about lab life? Seasoning?
No, and no.
I have read most of the ground lighting standards and I don't recall some big section about operating cycle of bulbs.
Perhaps you were not reading the standards applicable to LED vehicle signaling and marking lamps.
You asked me a very general question about "operating cycle," and I told you the answer.
Er...no, sir. I didn't. If you'll carefully review this whole thread, you'll see you are the only one who has used the phrase "operating cycle". I did, however, ask you a specific question about whether your products are tested for output maintenance over prolonged operation in accordance with the relevant SAE standards. It took awhile, but thank you for answering (no).
LEDs don't work the same way as incandescent bulbs.
Is that right? H'm. Are you sure? ;-)
LEDs need to be tested to stable operation
Automotive LED lamps need to be tested in accordance with certain protocols. They're in those SAE ground vehicle lighting standards you read most of.
