And 2 Leds more
there is one simple rule.. never trust a chinese company what they claim about leds.. they all claim that their 1w led has 5000 lumen and is true warm light. what you get is white or yellow light with 10 lumen..
Yeah... cob leds (or brand "cree") have anything better when it comes to light efficency and lifetime.. but they are hard to integrate on a pcb. also all cob leds which i used (even them with low watt) needs a heatsink...Sorry was my typo 60m range on the DS-2CD2T87G2-L. The multi led new Hik looks very interesting as you mentioned. The bin colour of any led is very important and more so the driver used to power it having modded many flashlights my favourite maglite 1 cell with a 5000mAh lithium battery and Cree LED which makes a true 1000 lumens.
