Do they make cree night lights now?

I'm looking for a super bright LED night light, to light up a room a lot more
at night than the old tech night lights. I realize that the "number of LED's"
is meaningless, I just want lumens.

Weren't there new LED's called "cree" or something, that were 3 or 4 watt
LED's and put out quite a bit of light? I want to find a night light with
something like that built in, not a "bulb" to add to some existing night
light.

I'm also looking for no flicker, as this is for the room where our pet birds
sleep - to keep them from getting night terrors from too dark a room. ( birds
do that if it's too dark where they sleep )

If pure white light is what you want that's fine. I've also
heard that this phosphor technique could also lower the efficiency
output of the LEDs? who knows. If you're just looking for reliability
of life use, then I guess it's fine.

All the common hardware stores sell LED night lights...

Not super bright ones, of 1-3 watts.

Then make up your mind (not that you started out well with the

cross-posting).

A night light is not supposed to light up a room. It's supposed to
provide a mild light so somebody doesn't stub their toe if they have to
get up in the middle of the night. You don't want a bright light because
you don't want it interrupting your sleep, but you also want it weak since
otherwise your eyes have to adjust to the bright light from total
darkness.

Light up a room is a different matter. It's regular lighting.

You can't get an answer until you actually define what you want.

They make fractional Watt LED night light bulb replacements. Walmart
sells them.

I use a 1.5 W LED lamp at my gates and it is too bright for a night
light.

Incandescent night lights use about 2 watts, that's all I'm asking in a LED
one.

watts != lumens. incandescents output more heat than light. thus their
two watts is minimal light. not comparable with led's at all.

figure out how many lumens your night light outputs, then search for
led's with /that/ figure, not wattage.

A night-light incandescent lamp (less than 5 watts) has a luminous
efficiency of less than 0.5%.

A lighting-class LED of less than 5 watts has luminous efficiency
closer to 5% or 10%.

That would indicate that for the same number of lumens out, you
probably want the LED to draw one tenth (or less) the power of an
incandescent used in a similar application.

PAR-type LED spotlights are in the 3-4W power class and are way way
too super bright to think about for night light use.

Wal-Mart and others sell LED night lights. I'd guesstimate that they
put 10-15mA through a single blueish-white LED with a 3V drop and IMHO
they are plenty bright. I tore one apart and it looks like they use
series capacitance and some kind of transzorb in parallel with the
LED, to start from 120V and at least somewhat efficiently limit
current through the LED.

The above numbers are raw lumens/watt. A more important issue rather
than raw lumens will be diffusing the LED to the point where it
doesn't glare as a point source. The Wal-Mart LED night lights start
with a diffused LED and then put a transluscent diffuser around it,
and even then it's way more obviously a point source than the larger
incandescent bulbs.

Yes you can.....................a monster LED with a big ceramic slab
heatsink, controlled by a variable PWM so the illumination can be set to
just what's required.
