re Lighting Power Compacts or not
I am setting up a 25 gal tank with the Amazonian decor, Angle (which
I've had for years, a couple of Discus and something really small.
Unfortuatly I am very confused about lighting this tank. I will be
useing CO2 (at a small rate). Going by the scale of 4W per gallon, I
believe 100W will be sufficient lighting.
Power Compacts (110W, one 6500K bulb, one 7100K bulb) -
- $180 fixture w/ lights and $45 each year (bulb replacement)
Fluorescents (VHO, with 2 bulbs either 2x40W or 40W + 75W) -
- $150 ballast w/ endcaps, 4 bulbs per year = $75
Regular Fluorescents (4 x 20W)
- $50 2 ballasts, 8 bulbs per year = $150
*Note: Assuming fluorescent bulbs last 6 months and power compacts 12
By my thinking, the power compacts make the best overall deal!!
Anyone have experience with pc lighting?? Any help would greatly be
I too looked very hard at the power compacts but decided they were to expensive
I ended up using T8 lamps and electronic ballasts; in addition the reflector
was built using mylar film from a hydroponics shop.
Reasons for my decision were as follows:
1. the power compacts are not available locally anywhere
2. I have seen the 28w power compacts and they are not a "standard
pinout" in any lighting book I can find.
3. The T8's have a life span of 12 - 24 months (depending on which
manufacturer you listen to). The ballasts are a standard item readily available
and I can use my old T12 sockets.
I ended up using a 4 tube ballast ballastronics 570-640x cost $32 cdn
two GE SPX 4100 cost $5.00 cdn
one Durotest 5000 cost $8.00 cdn
one Durotest Plant /AQ (5500K) cost $12.00 cdn
a reasonable setup that is working fine
Alternative might be the new T5 lamps which consume even less power and are the
most efficient fluorescents yet
as a start.
Good luck choosing
