I purchases one of the color changing LED lamps (#44 replacement) for
the "Clock Millions" target on my TZ. The lamp works fine (and looks
quite impressive, too), but now I get an unusual behavior. Whenever
the "Middle Right 5 Million" lamp is activated, the "Clock Millions"
LED lamp also lights, although much more dimly than normal. If I
replace the LED with a normal #44, the power must not be enough to
cause this behavior.

The "Middle Right 5 Million" lamp is right next to "Clock Millions" on
row 2.

Is a bit of 'power leak' typical in adjacent lamps on the same row -
and could it be enough to trigger the LED but not a regular lamp? (I
thought it normally worked the other way).

I thought this was interesting. Any thoughts? Anyone else try this
LED and have a similar experience?

The issue is that there is a small power leak on the column/row of
lamps that has enough juice to activate the LED. there is ways of
fixing the LED bulbs to not do this, but i havent made the fix into
production yet. I have seen this in my STTNG and Black SM.

I just noticed this in a new form on my BSD. When all lights are out,
ie in video mode, I have one LED that still is dimly lit, so its not
cross over from others in the matrix it is something else. I've only
installed about 7 LED's in this machine so far, and a majority of them
are dimly lit when they should not be.

I personally am not going to try and hunt down all the possible
"leaks", too much effort, I will just not buy more LED bulbs until it
is resolved in the bulbs.

Please take this as constructive feedback. I really like the look of
your bulbs, but am annoyed by this "leak." It has kept me from
ordering more bulbs and I think I am not the only one.

Thanks for the effort. I do realize you've put a lot of time into
getting these to market, but I think they need a little more work to
be a direct replacement.

Jason,

I understand and i have been working on this. It doesnt happen for all
bulbs and certain colors. I have actually seen the Incandescent bulbs
be slight lit also, but it so faint it does not get through the
insert. Right now i am working to two new circuits for the bulbs and
will try to work in the fix to make this anomaly go away. its a fine
line balance in getting the brightest effect and resistance to balance
this issue out. The fix also negates some of the power saving
benefits. Again, i am not happy with this issue and why i trying to
resolve it. But the over all benefits to reducing the heat loads and
power loads on the circuits in my opinion out weighs the slightly lit
LED. 90% of the applications you will not see this problem, only in
certain controlled lamps which, i am assuming are all 555 type bulbs,
not the 44. please let me know if i am wrong.

I am seeing it on 44 bulbs as well. Specifically I recall all 4 of the
blue ones I have installed have done it. And its one of these that is
dimly lit during video mode when no lamps should be lit.
