IT5 lamps are smaller in size (length and width) which makes T5's well suited for the low-profile, elegant fixtures that are especially popular for upscale retail, hospitality and commercial spaces like display cases or wall-washing. Its smaller scale allows for sleeker fluorescent direct/indirect surface mounted and pendant fixtures.

It should be remembered that the main characteristic that distinguishes T5 lamps from other families of fluorescent lamps is that they are designed to peak in their lumen ratings at 95°, compared to 77° for T12 and T8 lamps. This thermal characteristic provides higher light output in confined applications where there is little or no air circulation, and it provides more usable lumens per watt in indirect fixtures.

Fixtures for T5 can offer more uniform distribution (less "hot spots"), wider on-center spacing and shorter drop lengths for pendant-mounted fixtures. T5/HO fixtures can use fewer lamps to deliver light levels similar to other fluorescent technologies.

Facilities have found applications for T5 HO lamps in coves and cornices and in new direct/indirect fixtures, like the SIMKAR TDPW, designed to take advantage of the smaller-diameter lamp. Care needs to be taken to limit the use of T5 HO lamps in low ceiling applications because this lamp is very bright and can cause discomfort from glare if not shielded properly.

Some industrial fixtures also use T5 HO lamps, and the lamp is appropriate for many applications that require a high lumen-maintenance rating of 95%. This lamp only loses 5% of its initial lumen rating in the first 40% of its rated life.

I read this on another forum. Hope it helps.

thanks for the detailed info. after doing more research, i think i will probably end up with a MH / VHO combo. probably diy to save money

You welcome, I personally really like MH/VHO combos. I think you will be very happy with that setup.

Thinking in terms of bulb life that the Icecap would be the better choice.

A T5 HO 54 Watt has great color rendering (higher CRI than any Metal Halide) and very little color shift. I am just not sure the availability of a specialty lamp - meaning a kelvin temp over 4100. By the way, you do not want to overdrive your lamps. You cut down the lamp life cycle tremendously.

I am interested in manufacturing a high quality aluminum fixture with the T5 HO and a specular reflector.

This is only a true statement when dealing with the 4100K MH lamp. When the MH lamps reach 5500K and up to 20000K, The CRI is in the 90's. T-5 cannot compete with that..The cost is also going to be hard to keep down...

They do have little color shift though...Been doing a lot of reading on them... I still think MH is the way to go to reproduce the UV rays of the sun. Flourescent lighting no matter what wattage, had its limitations when it comes to the correct UV rays.

Timbo,
That is the MOST Incorrect statement i have ever seen and you need to read a little farther into research. JMO First off UV rays of the sun will never be in comparison to any Bulb wheather its flouresent, or MH. Kelvins is how we determine the wavelength and sufficent light needed in comparison to the sun. To say that a 14k MH compared to a 14k T5HO is different is just being goofy. Also timbo wattage has NOTHING to do with UV rays just a mere understanding of how much electricity is consumed by the bulb.
With that off my chest Let me give you an example you have:
1 39watt T5HO 10k flouresent bulb
then you take 1 400watt MH 10k bulb
Each one is running at peak performance, and using the same reflector efficency.
Now you place each one on the top of a tank. BUT to make things fair on electricity being used we will have to multiply the amount of T5's being used by 10 and thats being generous considering im not including ballast rating. So we have 10 T5HO's running and 1 MH using the same amount of electricity. So your telling me that wattage has to do with everything...HMM lets rethink that, maybe wattage has nothing to do with it (of course it dont)! OR some people say that MH penetrates the water better than T5's...Hmm thats dumb considering im guessing water dosent say: "hey MH your light can come through but T5 stay out!" So now its time to replace bulbs at the end of the year are you going to wanna spend about 100 or 30 on a bulb? Think about it Just my .02cents HTH JMHO
