1000W vs 4*250W

[Claudio D]

Hi all

My current lighting set up is
4 * 250W 10000K, (3pm to 11pm) mag ballast
2 * 400w 6500K (5pm to 10pm) mag ballast
4 actinics vho 110w each on a icecap 660 e-ballast. (1pm to 12midnght)

light is ok but really a little bit to yellow

for a 94"*24"* 39" tall (2.40*0.70*1.00 meters tall)

After a year is time to renew some bulbs and I am considering upgrading the ballas to electronic in order to save some on energy and improve on eficiency



I was considering

changing the 4 vho to powercompacts 96w each double actinics

Changing the 4 * 250W for one central 1000w 20000K on Lumateck e ballast
Changing the 2* 400W for 2*400W 14000k olso on Lumateck

the choice on ballast is motivated because I have a 240volt 2 fases electric wiring in place for the lighting that saves on energy cosumption over the regular 120 single fase and this the only company that I found over the internet wich sell 1000W e ballast.

The change for one 1000w instead of 4 * 250 also is motivated on eficiency and light penetration,because when moving to a 2000K I will lose some PAR and I want to compensate with intensity

please all possible comments are welcome

thank in advance to all

the change to powercompact is backwards vho is beter


the new lights would be closer to what you are looking for i think

Across that tank I would use 4 - SE 400watt Reeflux 12K with the VHO you currently have. You will love the color of the tank after that. If you need a litlle more "brightness" from the setup change 2 of the 12K refflux for SE XM 10K. I would also overdrive the MH bulbs using a Dual PFO HQI ballast for the 400 watters.

Any coments about ballast? changing to eballst, will drive the Reflux bulbs...

About the Vho you prefer them over power compact? why?

thanks
