Both my direct fit (uses ballast) conversions in the basement and my
dedicated LED fixture in the garage light immediately at full bright.

I have had some CFLs (spirals inside floodlight enclosures) that took
awhile to come on, but have never had a LED that didn't come on right away.


That's why I was curious about Tim's with the delay. He also said that
they were the direct wire in type, so that rules out anything to do with
the old ballast, etc. LEDs are solid state, don't need to warm up, use
very little power, are supplied with simple switching power supplies.
I can't figure out why there would be a delay. Or why you'd make them
that way when like you say, all the other LEDs you've seen, come on
instantly, as has been my experience. Maybe they figured out people with
old florescents expect the delay and will miss it?
