This should read 8-Lights.
650W PAR36 DWEs don't compare to ACLs at all. The closest comparable 120V lamp would be the FFN, PAR64 1000W VNSP, at 400,000 MBCP, and beam angle of 6°x12°.

However lighting loads are not like normal loads because of high inrush currents and very high neutral currents which generators hate and new versus old lamps have different characteristics, so calculations to 3 decimal points are not really valid.So I would round up the results by 5%ish and generator up by 30%ish
Re: More Phase Questions
Okay, refering to the second one here. I know how to figure out how many amps you need on each leg. But will the disconenct say how many amps it puts out so you know if the disconnect will handle it? Or what?
Second, how do you figure out these:
2. For feeder, do I need two grounded conductors?
3. For feeder, what is the minimum AWG of the grounding conductor?
4. This is for an outdoor festival. If I have to rent a generator, what size kVA do I need?
and
7) How many sets of 4/0 90°C Feeder with E1016 Cam-Lok connectors?

Re: More Phase Questions
Be careful to use the correct terminology here. Per the NEC:
groundING conductor = safety ground = green or bare wire. This does not carry current, except under fault condition.
groundED conductor = neutral = white wire. This is current carrying.
The two are not the same, and yes, you need both in this case! The only time you don't need the neutral is when the load is strictly three-phase; there are no 120 V loads. You always need the safety ground.
