DIY MH

[LiveRock]

Thanks, tanzy.

I have not made any purchase yet; just want to find out as much before I make the plunge.

yes, the setup I'm interested in is double-ended, rated 150W. I just want to know I can just buy ANY double-ended 150W MH bulb and plug it it.

[yazid]

I don't see the problem. If it is 150W HQI Ballast it should work with and double ended 150W bulb.

I just bought Venture 10K 150W HQI Double Ended Bulb to replace OSRAM 150W 6500K.

It should work.

Hello yazid

May I know where you bought the Venture 10K 150W HQI Double Ended bulb? Do I need extra protection for HQI and how much is it?

Thanks for your help.

Cheers!

Any double ended MH lamps can use high pressure sodium (HPS) /metal halide (MH) ballast plus a 4.2 KV igniter. Vossloh Schwabe, Magnetek are some of the ballast brands.

You need to get protective glass that screens out excessive UV A & B which DE bulbs definitely need... without which... you will find all your corals bleaching.... ask Robe.. he did it once a long long time ago... and within 20 mins... his acros started to RTN....

to ask

does a single end 250w iwasaki MH need protective glass too???

or can I just mount it up like this without any cover?

I have to diy my canopy.........

[Tanzy]

Not really. The outer envelope shields some UV, but a glass shield is good to prevent water from splashing on to the bulb.

Cool water + hot bulb = Explosive force with broken glass

[X_Japan]

yikes!

well well thanks for the advice......

anyway, issit advisable to mount it about 30cm above the water surface??

or less?

[Tanzy]

I mount mine at 9" above water. 30cm will be fine if you have a good reflector to direct the light back into the tank, but the spread will be bigger and less intense.

Thank you very much~

Since this thread isn't technically a DIY thread yet... I am moving this to the Marine Tank Equipment forum.

Robe... when ever you are ready with your pix and DIY descriptions... pls post!

Folks,

Went to Kelantan Lane or Road this afternoon with Nano and found a shop selling a complete MH 10K (Slyvannia 150W tube) with ballast attached (measuring 12" x 6" x 2.5") for only S$230.00 .

It's the same light setup as the one you see at AquaMart or ReefWorld.

Dirt cheap for a complete MH config.

Forgotten the shop name but already dreaming about it tonight on how to mount them to supplement my current MH.

Guess 250W or 400W MH are way beyond my budget. Have not heard anyone posting the prices they've paid for their DIY.

Hi Guys,

Can 2 X 150w Iwasaki 10k supplemented with 2 fl actinic good enough for a 100cm x 45cm x 45 cm tank?

Is the colour spectrum for the 150w saki white enough?

Is there a 10000K Iwasaki?

Is there a 10000K Iwasaki?

Sorry, just check again and they are only available in Japan.

So what if I use 2 20000K sakis. Would the lighting appear too blueish?

My current light hood holds 3 30W FLs. I would want to retrofit it with MH. What are the options available that won't cost a bomb?

[BarraCudaTM]

I tested and bought 2 20000K iwasaki, dont worry they are blueish white .. very nice color .. spade and phang saw that too

Hi barra

What is the wattage of the 20KK and how much you paid?

Thanks

[robe]

They're only available in 150w nothing higher than that otherwise would have bought them.

[Morgan]

Thanks robe.

To check out the 20kk Iwasakis,

Find Barracuda..........

Hah... he jus got 2 SE 150W from Eye Lighting... the GM even did a demo on the 20kk jus to present how intense the light source would be with proper reflectors...

You should check their latest range of pendents.... Chioh....

Spade, its time to post those pics you taken......

BTW, Bluish white light is what you would get from the 20kk Iwasakis....IMO... looks very good!!!!!!!!

And yes to add on, jus got my 2x 400W ballast... test run the Blueline on a 4.5kV ignitor..... works and now running in my reef....yeah!!!

[robe]

rrbot also has them in his tank. Bought them around 2 months back it should be sufficiently broken in to have the regular spectrum output.

RRbot, why don't u post a pic as well of your new tank?
