    Default Radio Shack white LED

    Why is the price $5.49? Insane!
    Is this a Nichia DS?
    I still might get one to see the bightness if it is.

    I bought Cree XR-E P4s for less and they were shipped free.

    The average consumer doesn't know that they can order 5mm LEDs in bulk (or singly, from DX and other similar sites) for about $0.10 a pop. Hence, stores that target the average consumer can charge whatever people are willing to pay.

    Most of their prices are highly inflated.

    Default Bought 'em!

    I stopped by and picked up the two pack just to try them out. They are 30Deg, so not too hot for flashlights but the interesting thing is, the color temp. Both are around 4000K so are a slightly warm white color.

    If anyone tries them, post back if your's were like mine.

    Are you going to try it as a direct drive replacement of a bi-pin bulb in a flashlight?
    Any comments on how well it would work in a 2 AA flashlight?

    go to a dollar store and buy a light with LEDs in it. 7kmcd is kinda weak these days for white LEDs most are 14-25k
    Fenix Split rings 1400+ sent, SWIVELS now available also!

    I think the output seems lower because they moderate wide angle, so they don't show a bright spot like the focused ones do. That is my understanding of mcd ratings. They seem just as bright as the other 5mm I've played with if total output is considered.

    As I said in another post, If you want something with a neutral white light, try these. This is how my packet turned out. If anyone else tries them, let me know if yours had the same tint. I really like the color. It is like my Golden Dragon light (in tint, not output!). After comparing these to a 4100K CFL, I'd say they are more 4500K in tint.

    For the other poster, They may be a good upgrade if you want a neutral tint and a floody beam.

    If these are reasonably efficient and neutral white, they may be a worthwhile substitute for LEDs in "nice" keychain lights, such as Fenix E0 type packaging. There if you're spending $20 on a light, IMO $1 is justifiable to improve the color rendition.

    I don't really see myself using too many white 5mm LEDs. These days I usualyl either use 3mm color LEDs pulling ~10mW for indicators on circuits, or quad-chip power LEDs consuming ~10 watts. Nothing in between.

    Re: $5.48 for the first one... not much more you can buy a warm white XR-E
