Well if we compare radians we should compare top of the line halide systems.
So for a 6 foot tank, you only need 3 xr30 and one 6ft halide kit per my knowledge of LED’s and Hamilton’s website listed these for 6 foot tanks. Let’s say you did 6 xr30’s just because.
3x radion xr30 G5 ~$2,520
Or
6x radios xr30 G5 ~$5,040
1x 6 foot halide kit ~$1,369 (+$300 for premium equipment)
Radion~ 570 watts or 1,140 watts
Halide~ 1,520 watts
0.57kWh x 8 hrs x $0.12 ~$0.5472/day
Or
1.14kWh x 8 hrs x $0.12 ~$1.0944/day
1.52kWh x 8 hrs x $0.12 ~$1.4592/day
$199.728/year
Or
$399.456/year
$532.608/year
Mounting XR30’s~
2 Tracks $210
6 track brackets for each light $126
2 arm sets for tracks $265
=
$601
With the halides you must replace-
- Ballast: 3-400w Magnetic M59 (Electronic available for an upgrade cost)
- T5 HO Bulbs: 2x 80 watt T5 HO 460nm royal blue & HO 2x 80 watt T5 HO 420nm actinic bulbs
Thats $207 in MH and $136 in T5’s, ($343)Per year.
I made an excel sheet to show which is the lowest cost overall per year. As you can see 3 Radions is best after 3 years. However that may be too low light, then at 9 years, the 6 radions are more for your money than the halides. So the best thing to do here is pay the upfront for the radions, then at the end of year 8 buy 3 more, second lighting mount etc. about that time you should be able to keep the high PAR corals so it makes sense lmaooo this way you make the most of your money.
The only instance you should buy Halides is if you are going to use them up to year 8 and not another year, which actually makes sense. Plus the differences in quality of light etc etc are not included here. Or if you are doing a low PAR tank you won’t need those big halides you could go smaller. I think I’m gonna switch to halides thats crazy
