Hey everyone!
The purpose of this question/thread is not to knock a product or cause any controversy, but I do think it is something that we all should look at.
I see many many people buying Mars II lights because they claim to use 5w chips... but yet I have to see any proof that the chips are in fact 5w chips.
I want to know what everyones thoughts are here...
Now I want to say, this is not a Mars II bashing thread, because I do own 3 mars II lights and they did work rather well for the price.... but I do not believe these are 5w chips....
OK...so nobody really knows what chips that Mars II uses, but I've seen on some references that it is Epistar, Epiled and Bridgelux I believe...
I went to Epistar and Bridgelux and downloaded every single LED diode product data sheet and could not find any 5w diodes that either of there companies offer. They are all 1w and 3w (with the exception of 850IR, 460nm, 450nm, and 940nm which epistar does make in 5w). So I am wondering...if the Mars II uses all 5w diodes, what chips are they using? They are obviously not Cree, Nichia or OSRAM which are the only 5w chips that I am aware of (other than maybe small companies)...
Also... being that my 400w Mars II LED has 80 chips and runs at 180w... this would mean that each chip is driven approx at 2.25w... If these were truely 5w chips, they should be driven upwards more around 3w-3.5w per chip right?? Most 3w Epistar chips driven at MAX would be around 2.6W, so it would make much more sense that Mars II uses 3w diodes, not 5w...
I am not confirming anything...this is just my speculation and I want to hear others opinions on it...
As many of you may know...I am one that likes the 100% truth, and I see a lot of people buying into the 5w hype without even having proof they are 5w diodes...
Another reason for my suspicion is I recently looked at the diodes for my Intelligent Gro LED which does use 3w diodes, and compared the diodes to the Mars II....Looks like the exact same diodes..(not all of them, but the blues, whites and reds) have many similarities, some looking identical...
So I want to see what everyone's thoughts were on this matter... I mean I'm not here to Knock Mars II and they do work...but if they are really only 3w diodes, then call them 3w lights.....I hate to see people being influenced on purchasing things by mis-information...*(I may be wrong too)
What are everyone thoughts....?
