LED Brightness Chart

[Badkitty]

i recently bought a lux meter,same model as makoto by chance. I got it because I keep seeing pics of people's blades..and comparison pics of how much brighter some are to others, but since i've only seen my p4 blue in TCSS trans poly tube with diffuser and a 90led string of cheap leds(practice).. i really have no basis to know just how bright mine are. I took a pic of my p4 , in the picture it looks super bright but in real life its not ahole lot brighter than the blue leds that were in my MR anikan i bought.

I built the same kind of setup as makoto , but during testing i noticed that the distance the blade is to the sensor makes a HUUUUGE difference on the reading. For example... my green led string (i'm using the same blade for each test) came out to 100lux , the MR anikan came out to 38. That was with the blade approx 6 1/2inch from the sensor in a totally blacked out box with 0lux reading to start. When i moved my blade 2inches away i got a reading of 530 and when i touched the blade to sensor i got 750.

Whether these readings are accurate ,regardless of distance from sensor, if we could establish a standard on how we test , then we could get a better feel for how bright our blades are from everyone else's.

Just my 2cents...or maybe 1/2 a cent since i'm new

Hey can whoever started the thread update the chart with the LedEngin info. That would be really great. Thanks all.

The person who started this thread hasn't logged onto the forums since Dec., so he's not likely to see your request any time soon.

If someone wants to post that information here, I can edit the first post and add that to it.

I am just trying to find and figure out the stock lamp (LED) setup for a Vader force action saber the plastic sabers. And then replace it with the same one or possibly brighter led. What websites can I find to purchase this. Thanks.
