First stick w/ the ldd-h's which top out at 1000mA..
1 18's will be easier to control the heat
2 Work w/ blufish wireless controller lite..
3) Have a higher voltage range i.e. L's are only good to 36V...which means their output is limited to 32V
4 Cheaper power supplies (based on 6 x 1 x 1.1(fudge factor of 10%)= 6.6A:
SP-320-36: MEAN WELL: Power Supplies & Wall Adapters
3553 (rough ave)x 6= 21,318 approx lumens..
THEY work just fine in this circumstance but are less flexible..
soo if you go w/ ldd-l's you need 36v and 1.5x 6 x1.1 = 10A
4514 x 6 = 27081 (@1400mA) so lets round it to 30,000
a bit overkill but just a quick find. Probably can find cheaper btw. Don't mean to scare you..:
HLG-600H-36B: MEAN WELL: Power Supplies & Wall Adapters
so it is $60 vs $112 for the PS...
Drivers are about the same cost.. roughly $7 each x 6 = $42..
TDK/Lambda 48V/21amp power
You really don't want to know what that costs..
opps forgot to add the blues in.. either add 2A or 3A .. ps still are good ..EXCEPT for the cheaper hp one.. a bit short at 12.5A.. Just adjust the blues to 1000mA drivers..
8.6A or 13A (Subtract 1A if changing blue drivers to 1000mA =12A, not really worth spending $70 extra $'s on the blues)
