does 4x54W T5 = 150W MH?

[terryansimon]

just wondering does the power generated by 4x54W T5...is it equivilant to a 150W MH?

it'll be lighting my 4ft by 2ft by 2.5ft (L/W/H)...

and ps I hope I got this in the correct thread. =\

its best u go for MH if u can afford the heat issues....coz mh light is from a point source whereas t5 wattage is spread out along the whole tube.....and to punch through the depth of water....t5 will lose to MH..

many threads in here about this issue already actually..hehehe

4 x 54w = 216w

against

1 x 150w = 150w

...guess u know which would be more economical.... i think ur use of type of light will fully depend on what types of corals u intend to keep.... maybe you could indicate ur livestocks

cheers!

[terryansimon]

oh shit. I didn't know. about the being discussed thing. hmm.

I know the advantage of a MH light...as in its a concentrated beam of light as compared to the spread radius of a T5. just wanted to know if multiplied by wattage, is it a same sort of comparisson to a MH.

thanks anyway. yeah coz I'm intending to get the Dimfix retrofit first. then when urh...the tank is more mature and when I'm richer...I'll get a set of MH lights. maybe like those by Weipro. or something. or if I'm rich enough, Giesseman. hurhur!

thats the problem. I don't know what I'll be keeping as yet. in fact, I haven't even gotten the tank yet, let alone the lights. only got the chiller, the return pump and the impending arrival of the EC 180.

I was just thinking long term, when I dare venture into corals....so yeah. was wondering if it'd be more cost effective to get a 2x54W ATI first now and get another 2x54W ATI later...or just jump straight into a MH. (=

ive seen a weipro from a fellow reefer, lighting up his 4ft tank..... things i've observed, first is i can really feel the heat oozing out and secondly, the ballast was

quite noisy... correct me if i'm wrong about my feedback about the weipro but those were things i have observed....

a piece of advice:

y dont u just diy ur mh lighting? i think a well planned set up is better than saying, "i'd use this now and if i can afford i'd buy that next time.." coz in the long run u'd be spending more than necessary.. don t get offended, just my point of view bro.... not intending to ridicule ur idea.. anyway, i think there r a few fellow reefers who would be willing to help u diy ur lighting, some maybe even be selling parts cheaper.....

also, i think u would need at least 2 x 150 mh for a 4ft tank.... i am using the same setup

no offence taken. constructive criticism. a very essential part in improving oneself. (=

yeah I've taken into account the DIY and upgrading possibilities next time. however, financial allowances would not allow for that. then again, I'll be contradicting myself by saying that I like the novelty of the dimmable light by ATI.

unless you know of someone who can DIY 2 x 150W MH plus maybe....two tubes of T5 for aesthetic purposes....with dimmable ballast. do you? (=

anyways thanks for the feedback! (=

last time ive seen planetq was selling his 2 x 250w mh diy set, all brand new but u need mogul, bulb.... ask him.... im not using any actinics; just 1 x 10k bulb and a 20k bulb but would be getting another 20k after seeing the result of the yellowish spectrum of 10k agains 20k

DIY t5 . 2 tubes . <$170

DIY 400watt SE 20kk With SpiderLIght <$250

eh? how on earth did you get such quotations? I'm interested. (=

[reefer guy]

hi spiderone!

just wanna ask where u could avail of the spiderlight reflector locally?

[Tanzy]

Watt for watt, T5 will be brighter than MH because it's a more efficient form of lighting but it's diffused light as opposed to a point source.
