Rebel Tri-star

[dj2rbo]

Hi people. I'm not trying to start a fight with anyone I'm just plain curious. The people who says that the rebel tri star isn't brighter than a lux 3 luxury v seoul because of optics are imo misinformed because maybe they never used it. if you stick with one color for all three of them and give them 1 amp is series its really bright. Really really really bright, with or w/o optics.

To be sure, it would be surprising if we even registered on their radar. But you have to admit, it is an odd coincidence. On the other hand:

1. 6-sided PCB mounts are commonly called "stars"
2. Presumably plenty of geeks work in the field of LEDs and related tech
3. A geek presented with the word "star" would naturally think "star wars" and/or "star trek"
4. A geek might, for a lark, propose the words "rebel" and "Endor" as product names, with non-geek top management being none the wiser

Then again, being geeks, it seems plausible that one or more of them were aware that their LEDs were being used to make lightsabers.

The rebel LED I have for says "Saber" on the pcb. Might be a coincidence...

Whoa! That's new to me. Now we seem to have moved beyond the realm of coincidence. The company that makes the LEDs that have been the light source of choice among sabersmiths for several years makes products that are ideal (?) for such use and gives them the names "Rebel," "Endor," and "Saber"?

I think you have it backwards Vargose the endor stars were the ones that X-wingband was using and the reg lens work fine. These are Endor http://www.luxeonstar.com/Luxeon-End...-LEDs-s/85.htm but they have been discountinued. The stars Agelessanarchy was talking about are the ones that are to far apart.

No, he had it right...xwingband was making them himself with a reflow soldering oven and using this star pad from led-tech.de:

That puts all three of the domes in a tight enough circle that they all fit under the standard 20mm lenses sold in the store here. The regular Endor Star doesn't work for that, since the led's are spaced too far apart..

I'm with you Matt. Google waves, for instance, it's filled with Firefly citation: never seen the "Don't worry capt'n, it's all shiny!" quote on crash?

Thanks Jay-gon.

What would REALLY make waves in the saber community is to have multiple dies under one dome. As far as I know Luxeon hasn't done this quite yet. I know LEDEngin, Cree, and possibly Seoul have. But if Luxeon could, man would we be in for a treat. Luxeon's reliability, brightness, and overall life would be that much better.

I have to start experimenting with the multiple dies under one dome LED's!

Multi die LEDs are well in use, and Luxeon hasn't been king of the roost in quite a while IMO. The P4s have Lux beat for every color save maybe red in brightness and power requirments. Even the once mighty Lux V was dethroned a long time ago. I personally don't find any use for luxeon except for maybe a cyan, and even then, you could get that with an RGB. Endor stars are about as useless as breasts on a nun, and don't give ANY advantage over any other LED on the market.

I can't get Cree stars here in Japan, but I've used plenty of LedEngin RGBAs and RGGBs, and they are excellent. They also offer 10W stars in the standard colors, and these are four dice under a single 6.2mm dome. But with all four dice connected in series, the forward voltage requirements are quite high, and vary between bins. For example, in green, the minimum forward voltage for bin H is 14.72V, but for bin N, it's 19.52V.

On the other hand, the current requirements are what we're accustomed to: 700mA to 1500mA (peak).

FenderBender may have some experience with these. Oh, wait. He responded while I was typing this. He put it more bluntly than I would have ("Endor stars are about as useless as breasts on a nun" is sure to end up in someone's signature, unless it gets censored. ), but, yeah, he captures my own feelings on the matter in a nutshell.

Oh I must have missed that difference. Sorry about that.
