Nowadays, more and more outdoor lovers are fond of choosing a suitable and favorable flashlight. But the problem is how to choose a proper or good flashlight? Many people do not have a clear idea or concept about this.
There are too many options on line. Usually, the shopping guidance on forum is really old fashioned. Therefore, here in this article, we are going to learn how to find good and suitable LED flashlights!
First of all, we need to choose the LED,CREE has many series and models, we will introduce XRE, XPG, XML series to you.
What is XRE Q5-WC，XPG R5-1A，XML T6-1B stand for?
Q5, R5, T6 are the level of LED light.
XRE has level P3 P4 Q2 Q3 Q4 Q5 R2
XPG has level R3 R 4 R5 SE S3
XML has level T4 T5 T6 U2 U3
Higher level has higher efficiency. Level 2 is 7% brighter than level 1, human eyes can’t tell differences.
XRE, XPG, XML stand for the package of LED.
Besides the models we just mentioned, there are also XRC, XPE, XPC, MCE, etc etc. Same package means same looking. XRE has the smallest lighting angel, that leads to a long distance lighting area. XPG got a bigger core-area than XRE, XML got the best lighting angel and core-area. The lighting cups of these two models are larger than XRE, floodlight is better. Better floodlight means better LED flashlights.
Generally, armatures focus on the luminance of central area. But luminance doesn’t means Luminous flux. The XRE Q5 may looks brighter than XML T6, but you won’t find that XML is better than XRE unless you compare them in dark night.
Hope this could help in choosing a good LED flashlights!
