Has anyone been brave enough to test out any of the newer crop of Lights
of America PAR type LED bulbs? The ones I see use rectangular LEDs
which look like leaded (not SMT) SOIC packages. Heatsinking on some
bulbs looks like they might just be getting the idea but after the showerhead
bulb experience (and they are still on the shelves...) you can't blame people
for being hesitant. Nevertheless, it would be useful if at least one person
on here was testing at least one of each type to see if things have improved,
or the same issues are still around.
I continue informally testing an MR16 3W spot which was purchased
last year. This is one with a grid of 42 small LEDs, with a common patch of
phosphor. It has passed the few-hundred hour mark with no apparent issues
other than flicker, and that the heatsink is minimal, which could be an issue in
high-ambient environment, which mine (somewhat intentionally) is not. I'm
using an old photo light meter for relative measurements over time.
Incidentally, one of their newer A19-size bulbs uses a weird column inside
the bulb, lined on three sides with tiny rectangular LEDs pointing outwards;
interesting but not sure I would trust it for heat dissipation.
