T-5 verses VHO

[gmeuser]

Hmmmm

Well as for T5,s being more effient. I think it would depend on the ballast. I am in electronics. The bulbs need a certain push and a certain voltage. The ballast is what eats the amps not the bulbs. I will try t5 setup on another tank. But I am going to look farther into it. I see that some say they have eight bulbs on a tank. I have that 210 with 4 VHO,s 165 watts a piece. That is two ballast.

The report about MH being a directed light. Well it is directed and allmost all lights are atleast the ones with mirrors. I would like to see a real report by other than the company. I will have all three types of lights but they will be on different size tanks so I really dont think it will prove anything. I am not willing to buy two more 210 gallon tanks.

I have read an report on the LED,s and thier spectrom and Par. It seems everyone is sure on the spectrum that is more liable for groth but I havent seen a report on the spectrom??? Has anyone seen one?

This refers back to the beginning of this thread, if you want MH information about bing a Point Source light as compared to fluorescents which aren't, take a look at sanjays research, all the information is available for you to read! Read is key here because most of these same questions I see are repeated every day & people don't seem to search enough & read what is available, we have this many many times over on this forum.

light

I am still at the sam equestion. No one really knows what par or what spectrom of light increases groth on a reef. I have read the articles and they say the same thing. They only know( not for sure) for clams. The rest of corals they dont. That is why I am saying every study here is about the lihght output. What should come first is what light output is needed. Tha would greatly help individuals on purchasing light equipment. i am still looking.

We have decided to ad anouter tank. it will be a custom 4ft by 5 ft by 18 inch deep. We are constantly invesutgating light sources..

lighting debates are never finished, just postponed:lol:

420 Nano Meters is the range your looking for to get the best coral growth! I'll see if I can search that for you.

I just want to share to my very little experience.

I am now using a 4x39 watt T5HO from my old 2x250 watt 10K MH + 2x 36" VHO.

I installed the T5HO and left the VHO so that I can still have the super actinic effect that I really want from my VHO.

One thing I noticed that when I compared my 2x39 watt T5 against my 2x95 watt VHO. You cant even see the VHO turning ON and OFF. No effect at all. The T5 was so bright, you cant see the effect of VHO.

Maybe the bulb is so old... then I bought 2 new VHO. Still the same effect.

So right now, Im just going to remove my VHO and buy another 2x39 watt ATI blueplus.

Just my 2 cents.

2x250 watt 10k MH Reeflux.

4x39 watt T5HO - 2xATI Aquablue 2xATI Blueplus

The same camera setting on manual mode.... Almost same brightness.

A picture is worth a thousand words

 

[Scooterman]

Cesar, the second pic is just the T5's? Looks great, are you getting growth from your sps or is that just starting out?

 

[Katchupoy]

That picture was Day 1 of T5HO. March 17, 2007. Right now, I have to raise it up around 12 inches above water because my zoas dont open up if they are 4 inches above water.

Maybe I will lower it as time goes by.

Does anyone have PAR comparisons between 110W VHO's and 54W T5's? I'm moving the contents of my reef to a 75 gal tank this summer sometime, and I'm thinking about replacing the PC's in my VHO/PC combo with 2 54W T5's...I'm wondering if the T5's are intense enough to use as my "white" light source and suppliment them with 2 x 110W VHO actinics, or if this combo would end up being too "blue" looking to the eye....

Here are the par readings but not without the VHO...

The highest are the ATI Aquablue and GE 6500K

par readings...

The GE 3000K had a little more PAR than the 6500K, I probably wouldn't try it with just 4 lamps.
