You probably can&rsquo;t tell the difference between 20mA and 10mA, and even 5mA is plenty bright.</p> Mitchell.Spanheimer urn:uuid:aeeba024-c821-7bbc-517f-ba1396139670 2016-08-20T22:50:08-06:00 <p>An Arduino can only drive about 100 ma total, so if you are using more than 5 of these on one Arduino you might start having problems, unless you connect transistors to the outputs. Use google to search for transistor driving circuits for Arduino. Hope this helps.</p> bobdabiulder urn:uuid:e87bcabc-c3a3-c788-912c-7232e822a0b6 2016-06-18T22:10:06-06:00 <p>Yes. Look on the dark web for &ldquo;legitimate authorization certificate.&rdquo; I&rsquo;m sure you&rsquo;ll find what you&rsquo;re looking for, especially if you put your credit card number out there ;)</p> darrylh urn:uuid:2e984263-d03f-72cf-cd36-c8d811e9a5fe 2014-08-18T14:12:21-06:00 <p>What is this, &ldquo;Not to be handled by unauthorized personnel&rdquo;? Where might one obtain the necessary authorization? Is there some Internet site where I can put in my credit card number and download a &ldquo;legitimate&rdquo; authorization certificate?</p> xtopher urn:uuid:dbc37018-96e7-87aa-f2ce-b9ca576e578c 2014-02-03T09:41:22-07:00 <p>They are the same LED, looks like the info just wasn&rsquo;t entered the same way for both. Both these LEDs and the COM-00531s have a Min. Forward Voltage of 3.2V with a Max Forward Voltage of 3.4V. I hope this clears things up! :D</p> Customer #215975 urn:uuid:eb67b5c6-606f-c19b-817a-adefe3d813ad 2014-01-31T03:08:08-07:00 <p>*These have a stated 3.2V forward drop, while COM-00531 has a stated 3.4V forward drop. Am I missing something or are they actually slightly different?</p> NVDPas urn:uuid:5912e6cd-e07b-12af-727f-8b3b83d4883a 2012-01-30T12:06:49-07:00 <p>The hundred pack is even cheaper. One LED is 1 cent cheaper than the LEDs in this package.</p> RobertC. urn:uuid:b3b5080a-82e0-860f-024e-f62704a39aff 2011-10-04T10:14:01-06:00 <p>yes.</p> Henderson urn:uuid:420100fc-bf98-dd7a-3446-e777857837db 2011-10-03T19:30:50-06:00 <p>are these the same as the single bright white leds (sku: COM-00531)?</p> Jonathan Bruneau urn:uuid:80804bb2-338b-92c3-d1f6-8817630c2aff 2011-08-03T20:44:07-06:00 <p>This is probably the best price I&rsquo;ve found for white LEDs. Even surplus stores don&rsquo;t match this price!

To my eyes they look less powerful than the normal red led I got in my arduino kit.<br/> Is there any other way to check instead of using the normal led sketch from arduino? Also, is there any encreasing the currante on arduino pins? Please let me know asap thanks a lot</p> Julio2010 urn:uuid:6bb15744-6dd4-0690-dbb5-97f20b1bdca5 2011-01-04T13:21:33-07:00 <p>Im trying to make my own LED lamp for my desk and I was wondering if these LEDs would be bright enough to substitute my desk lamp? Would I have to use the 25 of them? Appreciate any suggestion.
