LEDs in stead of a lamp

[GSM]

Hi,

I have an application where I need to produce light equal to a smaller lamp
by using a number of LEDs (the environment is too rough for a lamp)
Would appreciate advice on which LEDs would be best to use.
In other words, who manufactures really bright (white) LEDs?

Thanx in advance

Nichia NSPW500BS for a narrow, very bright light beam. You can order
20 deg, 6400 mCd 5 mm LEDs from http://www.whitelightled.com/ for a
dollar apiece plus postage.

I bought a hundred white LEDs from a Hong Kong maker on Ebay for about
$.25 each, and I believe they have a lot lower light output than the
advertised 5000 mCd. But since they advertised them as "5000 mCd max,
3000 typical" with no minimum given, I have no grounds to complain.
So be careful, be very, very careful when purchasing LEDs, because you
will definitely get what you pay for, or a lot less. "TANSTAAFL"[1]
If you want premium quality, you _will_ have to pay for them.

Oh, yeah, I forgot to mention. I got some white Luxeon Star/O (with
lens assy) 1 Watt LEDs for $16 each from Mark Hannah Surplus. They're
labeled LXHLNW98. You can now get the 5 Watters, but I've read that
they do get hot, so you need to dissipate the heat. For that matter,
the 1 Watter above gets hot, so you need to dissipate the heat, also.
But obviously it's not as nuch as the 5W! )
