Hb Rgb Led???

[Logan Cade]

what do you think are the best viewing angles, because I found a good supply of rgb 5mm leds but their viewing angle is only 25 degrees (I'm building a makoto style blade so facts and help is great.)

never mind found a great site with good rgb's http://www.ledshoppe.com

I purchased some of these LED’s in the link below off Ebay and to be honest I’m not to impressed by them.

They only have a 25 degree viewing angle and 8000 mcd. Looking at that other site you posted:

I’m wondering if the 8000 mcd in mine is a combined (R+G+B) luminous intensity.

The ones in your post show RED at 5000mcd, Blue at 5500mcd and Green at 6000mcd. Would that combine to 16,500mcd?
Plus they have a greater viewing angle of what I believe to be 40 degrees.

There’s also this site, which if you scroll down to the 5mm LED’s you’ll see they have common anode and common Cathode LED’s at 9400mcd @ 35-40 degrees which also turns out to be a combined R+G+B. They also show a 1900mcd with a viewing angle of 85-100degrees.

What’s everyone’s opinion, I don’t know how many of you guys have dealt with this before.

Yes, that "8000mcd" is supposed to be the combined R+G+B (aka white). However the tall tale of LED brightness is somewhat furthered on ebay. In other words, they have a tendancy to exaggerate..

I've been testing out the RGB Rebel star LEDs and even at 700 mA they are almost as bright as a luxeon 3. I didn't have a 1000 mA buckpuck to try but so far so good. Of course I was running on 6 AA sized batteries...

I also tested the color combos and even though the LEDs are separate on the board, when you light two of them together they do combine to form a different color. I got some nice colors out of them.

When I put all three together though it makes a strange orange/pink color.

The only drawback to these LEDs is that they have very small contacts on the board and as a result difficult to solder. With 6 wires you will have to manuever around the lens holder. It does fit the heatsink with the groves on the side if you use thin enough gauge wire. I'm using the inside wire from a phone cord.
