LED Purchase

[scummins]

I am looking for some information on LED's. I need to purchase some for a project and they need to have a very high light emission and also intense. They are going to be warning light, but a xenon strobe is too intense for the application. How can I find LED's in a catalog that are going to do this for me. The catalogs rate everything in mCD (mila-candela). This is just a rating of the intensity of light at a certain or given angle. The catalogs do not give light emission parameters.

The LED data sheets at Agilent are pretty comprehensive.

I fail to see why that information is insufficient. The higher the mcd's, generally, the brighter.

Your problem, it seems to me, is that you don't actually have a detailed specification for how bright an LED you need. Therefore, it behooves you to get some samples and test them out in your application to determine the requirement empirically.
