is the model of this mh enough?

[ReDDeviLs]

hi bros,

i'm currently thinking if i should go for a mh for my 2.5ftby1.5by1.5ft tank..

saw this

HIT-DE 150(20K) BLUE UV protected

150W

RX7s-24

is this suitable? i have an anemone in my 2.5ft tank..

can anyone advise me on this? thanks

[ReDDeviLs]

no 1?

i use to use my mh on a 2.5 ft, but mine 2.5 have a centre brcing so gotta shif the mh slightly to the sides, think is more than enough for 1.5ft hieght.

U can used t5 or pl if u have min 3 inches of dsb.

maybe u can try 1 X 70w mh.

i guess can just hang it slightly higher and it will be fine? hate the stupid centre brace.....

[ben]

yeah, it will work.

[ReDDeviLs]

i have about 3inch dsb.. so a 70watt is good enough?

if next time im using it for a taller tank,than i just need to change the bulb right?

[ReDDeviLs]

sorry for my silly question but what is the difference between

BLUE UV protected and non-UV protected?

No, u will nd to change the ballast set as well. Would strongly suggest u to go for 150W min. IMO, 70W is too weak....use it for refugium still ok.

UV protected meanin the bulb is made of UV glass to shield off those harmful UV rays. As for non UV protected = the opposite. Unlike SE bulbs DE bulbs are not UV protected. So tats y, pple gettin DE MH set always hunt for UV glass (if not included in the set).

the higher the wattage the more the heat right? so if i use 2 55 watt pl lights compared to a single 150watt MH, does tt mean that the pl combi emmits more heat??

thnking of getting MH for my 2footer

i see,but SE bulbs comes with 250 and 400watts only..150 dun have SE bulb right?

what about the base RX7s-24 is this the ballast?

and regarding the 70watts if need to change to 150watts u mention that i have to change the ballast is the ballast expensive?

sorry to ask so much questions but trying to learn

Tats true....the higher wattage not only produce more heat but also cost more (in terms of PUB bills). 2x55W PL = 110W so still less heat as compared to the 150W MH. But do note tat 110W only means tat u had 55W per tube per "10inches depth penetration"= (assumption). And 2 x 55W PL doesn't mean u got "20inches depth penetration". U only get "10inches penetration" from each tube, tats all. But a single 150W MH will give u 20inches depth penetration (assumption) and the same theory applies....havin 2x150W doesn't mean havin light penetration up to 40inches of depth.

Now tat i recalled, think SE do come in 150W version. I ever bought a 250W MH set from a fella reefer here and its supposingly to be 250W bulb but the bulb kinda of shorter and smaller than the actual 250W bulb and suprisingly can be screw into the E40 holder and powered up by the 250W ballast w/o blowin the bulb . Since its suppose to be a radium bulb but its kinda of yellowish so a check with the seller confirm its not a 250W bulb and got it changed.

A check with victron would be advisable to see if they carry 150W SE but the base shd be different, think its a E27 or E37(not sure) holder or mayb E40 holder will work too.

The base u mentioned shd be the holder for the DE bulb, like E40 is the holder for the 250/ 400W SE bulb. Take it as u r using 250W ballast now...if u wanna up to 400W, u will nd to change the ballast. ballast are not really tat expensive....its the bulb tats $$$.

thanks alot actually i saw the lights selling at viclite.com so i though i will be dropping by to get the mh.. thanks
