I just got my string of LED Christmas bulbs. It comes with red, orange, yellow, green, blue, and purple "bulbs". The purple appears to be a white LED with a purple "bulb" around it; the others appear to be LEDs in their native colors.
As a whole, I think they're brighter than 2002 Foreverbrights, but I'll have to go compare them side-by-side before I can make that assessment for sure.
There are no spare bulbs or fuses with the set, so if you blow one or the other, you're SOL. /ubbthreads/images/graemlins/icon15.gif
(Edit) There ARE two spare fuses with the set; I found them in a small plastic baggie on the receptacle end of the string, rather than at the plug end where you usually find them.
The white box they come in is not marked with "Fiber Optic Designs" or "Foreverbright"
It has the white, black, and orange Brookstone barcode label, plus another label that reads:
"SKU #000040135 70-Lamp C6 Strawberry, Multicolor Lamps"
Guess I'll have to take some pictures of them and mail them to the guy who runs Foreverbright and see if these are his.
(Edit) These lights DO look a little brighter than the 2002 Foreverbrights. The green LEDs appear to be InGaN types instead of the much dimmer GaAlP or GaP yellow-green LEDs in the other set, and the blues are a greener color (they look to be around 475nm), probably GaN on sapphire instead of the 430nm blue LEDs in the other set. The greens and blues are also significantly brighter than the ones in the other set.
Guess it's time to get out my diffraction grating glasses and have a look...
(Edit) The purple ones are definitely white LEDs with a purple "bulb" around them. The blue and green are InGaN, the yellow, orange, and red are conventional chemistry AlGaAsP GaAlAsP and InGaAlP type LEDs; all but the purple are quite expected to find in LED Christmas lights.
The "purple" ones are probably whites with a purple covering because real violet LEDs have such a short lifetime when compared to the rest, the near-UV component would cause unwanted yellowing of the outer bulb and unwanted fluorescence of other materials outside the light strings, and wavelengths that short might not look as bright as the other lamps in the set.
(Edit) I emailed Fiber Optic Designs, so I'll know soon if these are Forever Bright 2003 or some other brand.
