We don't have any really good comprehensive threads on T5HO lighting on NR, so I thought it was about time one got started.
I've been doing a lot of recent research on T5HO after buying a 24" 4x24w T5HO fixture from HelloLights.com at the incredible price of $100.

One of the really cool things about T5HO is the endless bulb combinations that can be used to produce various lighting effects.
Below are some pics and bulb information from different NR members who are using T5HO.

Comment from BK on above bulb combo-- "For what its worth, I'm replacing the 6500K. The tank is just too yellow for my tastes, but not by much. I just want a bit more blue."

here is one with 4 bulbs.Its hard to show in my pics but this is close to true color as i can get.It works very well and not pink at all in person.Ill get one of the 6 bulb later.Its just a tiny bit more white and very bright

2 ATI Blue+
1 KZ Fiji Purple
1 GE6500

Some excellent information on T5HO including different bulb combos and PAR values can be found here:
http://tfivetesting.googlepages.com/

I will continue to add FTS w/bulb combos as I find them.
In the interests of keeping this in a more useable format, if you have a tank with a T5HO fixture, please PM me your FTS and bulb combo to add to this post, instead of posting it yourself.
That way I can hopefully just keep all the pics together here instead of having them in different places all over the thread.
I will be continuing to post much more info that I have gleaned from various places and people over the next couple of days.

This is a great Idea, It was always a pain to try and search through threads to find which bulbs looked best. BTW I used Geismann bulbs, next time I am going to try ATI.

edit: Okay, I'm still collecting my info, but I'll be editing this post later on. Feel free to correct any mistakes I've made or help clarify some statements. I've temporarily removed references to most fixture/ballast brands due to there being many changes in quality.


What is a T5?

The bulbs we are talking about are "T5HO fluorescents" (aka T5-HO), but I will use the term "T5" from now on.

First, a T5 is a fluorescent bulb, which means it uses electricity to "excite mercury vapor" (yes mercury) to emit ultraviolet light. This ultraviolet light then hits phosphors (which are the whitish coating on the inside surface of the tube), which are excited to emit visible light. This reemission of light at a different energy (UV light is higher energy than visible light) is called fluorescence, which is where these lights get their name from. This is a cool video on how commercial fluorescents are made (T5s in the hobby are straight tubes, not U-curved like those in the video).

WARNING: Some companies choose to label PCs (Power Compact Fluorescents) as T5s or "T5 PC", but they are a different type of bulb than what I'm talking about because they have twin tubes on one bulb instead of a single tube like the T5s of this thread. However, I have observed my own Current and Coralife PC bulbs are actually 6/8" in diameter, so a proper term could be T6. Some other manufacturers will call PC fixtures "T6". In any case, PC bulbs look like this, and T5s look like this.

The designation of a fluorescent tube comes from a code of F##T##, where F signifies fluorescent, the first number for the wattage, T for tubular bulb shape, and the last number for the diameter (measured in eighths of an inch). So, a F24T12 is a 24W tubular fluorescent bulb with a 12/8" diameter. T5s are therefore 5/8" in diameter. Most of the vendors in our hobby don't write the "F" and just state the wattage outright (i.e. a "39W T5HO fluorescent").

The "HO" signifies "high-output" lamps which are brighter (and use more watts) than normal output (NO) bulbs of the same length, and they need to have suitable ballasts to work properly. Likewise, VHO stands for very-high-output, and it is currently used to designate "overdriven" (higher output than what is listed) bulbs on ballasts like the Icecap 430/660.

Things to think about when buying a T5 fixture (roughly in order of importance): reflectors, bulbs (these are easy to change), and ballasts.

Ballasts: Most of the ones offered seem to be okay, and they don't make a huge difference. If you decide to get a ballast separately, remember that the specific wattages of T5HO bulbs should be listed on the ballast's label to ensure safe usage. The Icecap 660/460 ballasts are used on "T5-VHO" fixtures because they overdrives the bulbs to around twice the listed wattage. This is great for limited spaces, but the bulbs need to have cooling fans and may age faster. More recently, there have been bulbs that are specifically designed as T5VHO with specialized ballasts, like those on the TEK "light ultra elite" fixtures.

Bulbs: ATI, UVL, Giesemann, Korallen-Zucht and some other manufacturers have a wide variety of bulbs that put out great PAR (photosynthetically active radiation). One con with Current USA and other less expensive fixures is that their stock bulbs are usually limited in color selection (usually the standard "10000K" and "actinic"). The "10000K" was for growth while the "actinic" was for color. The problem that is some higher-end bulbs, like the ATI aquablue special, have good PAR ratings for growth while also enough blue spectrum to avoid getting any pure actinics. Bulbs usually have peaks in output at different wavelengths (corresponding to colors in the visible spectrum), and so it's useful to see a spectrum chart of a bulb. So, switching your bulbs is a hidden cost that you must consider when calculating where you shop.

Reflectors: These are what everyone keeps harping on when comparing T5s to MH. A T5 is similar to a standard PC in wattage, but it's advantage is having a single tube that can get more light in the tank with a proper reflector. You can think of it in another way: you pay for the energy to light the lamp, and the next step is to effectively get all that light down into the tank.

The less expensive T5 fixtures often have just a flat reflector with bulbs are packed like sardines (similar to a PC fixture). The next step up is fixtures with an "individually contoured reflector" which is one piece of metal folded between each bulb. Finally, there are "individual (parabolic) reflectors" that act like a flashlight to reflect the most light, even from the back of the bulb.

Here is a good link on T5 spectrum charts to know just what colors are actually produced by bulbs that may be similar to the naked eye.

Yeah, the stock bulbs with the Sundial are not nearly as blue. A friend of mine suggested that combo for a bluer look at it worked. My acro responded well, went from olive green to lime green with baby blue growth tips :D

Love that color Travis. I might have to add those four bulbs to the Current Outer Orbit that is on my RSM. I already have a 150W 14000K Phoenix in there with supplemental actinics, but nowhere near as nice looking as yours. thanks for posting.

Do your colors really look that blue in real life, or does your camera make it look a little bluer?

For comparison:
All pics taken on manual setting with exact same settings. Straight form the camera, no processing in photoshop. Not exactly how it looks in person, but gives a good look at different combos.
Please ignore my tank...its under going a rescape and the corals are pissed because I keep turning off the lights to change lamps.

Useless comment, but great thread guys.

Masterbuilder: those side-by-side bulb combos and pictures were great. It's perfect for deciding which bulbs to order. You might want to merge your photo post with your numbers post into a single post with a total par for all 4 bulbs so you can see the photo and total par for each bulb combo.

I'll see if I can go do that myself in a bit here, thanks for the suggestion.

Wawawang has contributed the following pic of his tank with just a KZ Fiji Purple bulb over it:

Posted Image

He gave the following commentary on the bulb:
"That is close to real life as far as the color. I used the same camera and settings for this pic for my latest fts. It is a pinkish purple color and its very bright. The colors it effects the most is red, orange, pink as far as pop. My orange digi and my sunset changed to a orangey pink color when i went to this light setup."

According to Masterbuilder's earlier post, the KZ Fiji Purple bulb has a PAR of 330.
