I understand that, and that is part of why I am still holding out hope for actual specs and useful reviews. Though I do note that it seems to me that an array would have to have a focus distance for the target beam angle and any other distance would result in a larger effective beam angle.
Regardless, what I have seen in the industry is that small light heads with multiple emitters generally do NOT have beams that are nearly as tight as what I would prefer. Especially in relatively inexpensive lights. Thus my skepticism. I was HOPING for a D620 with a bigger battery pack and a tighter beam angle - and nothing else (unless they could also make it variable focus). This D630 is simply not that - at all.
