Regarding lumens and heat excluded, in honesty and where flood is concerned(and throw) can we ever have enough................i dont believe we can. There will always be a hunger for more and more..........human nature imho.
A 20,000lm flood beast out today, 6 months a 25k lumen flood monster.....................i know for a fact the people who have bought the 20k one would want the 25k
Throw the same, 1000kcd today, 2000kcd in a few month.............of course you will bite
The brighter the flood, the further it will reach out to a point you may get 500-1000kcd with flood................pure flood...............imagine that and look back in a few years to this!
200kcd from the F version............not a million miles away
And dont forget, you need to go really to 80k lumens for it to look twice as bright............
Star for now 4 F versions will have to do
