newbs beware

[cjsrch]

I think the powerful ripple effect alone would sway most towards MH.

Also a good % of reefers use vho supplements with thier MH, why would you want them to choose one or the other when both have thier qualities?

mh explode.. and are a hazard. that alone should be reason enough not to use them even if they were suppirior. ever burn your self on one.
your not even suppose to TOUCH mh when cool since the oil on your skin can danmage the bulb.

ever get a splash of water on one and have it burst. just for safty vho is better as they are the same heat output but have it over spead out area ( this allows more efficiant cooling by air as well as it not blowingup in your face ) it is a myth that vho put off less btu's altho they are cooler running. and retain less heat

Hope you were kidding about the incandescent... Careful cjsrch being close minded in this hobby can and probably will cause you some problems.

No more needless arguments or threads such as this ok?

Be good,

actualy i was serius about incandecant. but not as main light. jsut to cause the glitter lines. i think a few leds clumped together would do better tho.

 

[tinyreef]

trackabale light... why it dosnt affect anything..

only morphology or structure/shape of the coral. subsequent side-effects could alter growth, health, direction of growth. i'm nitpicking tho because very few people use tracking lights (so i'll call that a draw, how many people dim their vho's?)

stimm penetrates teh same. same streangth on;ly reason taht the sun makes a diff on the ocean as it moves across the sky is the earth ios round.

not quite sure what you mean there. but you yourself noted light penetration ain't the same between the two, mh's have greater penetration. the round thing comment, i'm not sure what you're getting at.

test show no color shifts in vho after 2 years. new ballast are responsiable for that.

uh, no. the phosphor makeup does that. intensity does lowers tho, hence fluorescents do eventually go out (spectrum goes too but again nitpicking). we just don't pickup the diff in dropoff until it's really noticeable, i.e. dark. check your corals after a year, they change tone/color/shape due to the dropoff in light. don't be cheap.

but it is a fact [emphasis added] that vho can keep the same coral as mh and be jsut as nice.

didn't someone on this thread say something about stating "facts"? it's late, i could've been imagining it. cya tomorrow, g'nite.

Here is a link to a link to Sanjay's lighting tests - he is not affiliated with selling lighting.

You can also look at some of the lighting articles in Advanced Aquarist, http://www.advancedaquarist.com/

What studies of VHO lighting can you point us to? Without such studies, it will be very difficult to get people to believe you.

VHO are just as dangerous as anything else in this hobby. There are numerous threads on RDO and other sites noting house fires from VHO endcaps, as well as many many people who have had VHO endcaps melt and almost start house fires.

I started with VHO only systems and was unable to have any kind of thriving SPS - they just limped along. With MH, I do. A local club had a tank in an LFS with VHO and had very limited success with SPS, the same SPS that were growing like weeds in MH lit tanks.

BTW,
We don't all love GARF - and that is putting it mildly. Do a little poking around here and on other reef boards.

 

[cjsrch]

one other thing. i think chemistry of water is just as if not more important then lighting.

oh i was saying the newer ballast make make the bulbs last longer.


i think someday ill set up half vho half mh tank see what happens.

Have you ever run a tank with MH?

Still interested in links to studies of VHO that support your claims.

 

[cjsrch]

research your self. its like page 10 billion when you google it . dont care for citing it all tonight. it will show up here eventualy

That makes your argument seem very weak indeed. If you are not even willing to back up your claims, not only will your claims not be taken seriously, but most people will write you off as a troll.

You are making extreme claims, but providing no evidence, while the other 'side' has already provided evidence that you seem to think didn't exist (a non selling site with info). Because you are the one making the claims, you bear the burden of providing some evidence to back them up.

For starters, give us one site (a site not selling lights) that compares VHO to MH and says they are basically equal. We'll go from there. :mrgreen:

Hi cjsrch,

It is solely the burden of the claimant to substatiate his/her claim.

I agree you don't need MH to succeed. But your claim that VHO is better must be backed up with data. I have apogee PAR meters that tell a different story. Not to mention well over a decade of experience with both types of lighting.

VHO technology has stagnanted for the past decade. There are continual improvements in MH, most recently double ended 400W halides and a hole slew of new bulb types to choose from.

i said i would do it when im not tirerd. dont act like im not going to supply research.

I just want to add a couple of points here:

I have 950 watts of halide light over a 4 foot long reef. When the cool morning northern winter sun hits the tank, it is still much brighter than my halides. Imagine an equatorial noonday sun in shallow water! Sure you can run a tank on VHO, or T5s, but it isn't better.

Regarding safety- if you search the boards you will find a huge number of fires caused by loose connections in german 3 part vho endcaps; the ones most people use. My point is just that any lighting can be hazardous if improperly installed, but the idea that MH bulbs are explode on a regular basis is incorrect.

 

[ChrisRD]

Sure, VHO, PC, T-5, are fine for reef lighting in many cases, but being diffused light sources, they will never be able to achieve the irradiance levels or penetrate like halides can. This is physics - not opinion.

Also, halides can produce more light for the power they consume - this is why they are so popular in commercial applications where a lot of light is needed for the lowest operational dollar. For reefkeepers this translates to greater energy efficiency and less heat for the amount of light that is actually getting to your corals.

Nobody is pushing halides - if fluorescents are your thing that's fine. For those that have been in the hobby for a while, however, and have tried several lighting setups, most tend to end-up with halides. That should tell you something...

IBTL.

Don't think you can beat a MH. Definitely my next purchase when it comes to lighting.

I particularly like this one:

i think chemistry of water is just as if not more important then lighting.

that's stating the obvious imo. which is the most important: food, water, or air? i can live without food or water for a month to a week, respectively. but breathing in poisonous air will last me a few minutes.

similar circumstances for marine life where their "air" is the water.

i think someday ill set up half vho half mh tank see what happens.

[sarcasm]that's so 20th century. [/sarcasm]

but really, i think you'll be pleased with the results of combining the best of both worlds (imo).

cj, your claims are just a bit outlandish and reckless, especially for the NRF.

I'm beginning to agree with cjsrch...he states his case well. All you other people need to go do some research.


I'm just kicking myself that I missed this thread yesterday.

Got that research for us yet?

I can see how that might have happened.
