light movers...are they as effective as fixed lamps?

OK, so I'm thinking of using a light mover in my bloom room, 5'x10'.
I currently burn a 600 & a 1000 evenly spaced.I would like to be able to use only one if I could achieve the same results...These are my lamps, my space is long & narrow, so I wonder if strategic placement would allow sufficient light to wash-out of the ends of say, a 6' rail to maintain some kind of constant coverage throughout each pass.(I feel like I waste allot of light against the side walls, so that is no issue in MY room.).....anyone know 1st hand if, & how this will effect yield, & or bud dencity?
s.loner.

They are very effectice and wont cause any difference to yield, I had one for a few years.

I've got a 10' rail in a 12'x12' space and the ladies love it.More of the sun's movement and such.It also helps temp variances.IMO

so, the MOTION of the light can have an effect on the plants behavior? How?...by that I mean, what sort of difference could I expect to see in my PLANTS not just my light bill?

ps........temps are NO prob. in this room, chillin' 74-78degrees, lights on!

light movers supply light to areas of the plant that normally under fixed lighting wont be getting light due to fan leaves and bigger top buds.so as the light moves those areas that are constantly shaded are going to get light and grow bigger and fuller mid to lower buds.light movers are awesome and will increase your yields.

I have heard you get less huge colas with them. Is there any truth to this?
