I only wish some one in town had T5 lighting so I could put an end to this nonsense once and for all.

considering 150 DE with a good reflector put out higher PAR levels than a 400 (Sanjays test not mine) with a ok reflector, I don't see how anyone could think a florescent tube could put out more.. T5's are nothing new they have been used in industry for a long time. hell a PC is a T4 which means theoretically it should have more intensity than a T5.

but if anyone in Town has a T5 set up and is willing to let me hook up my meter in there tank.. let me know.

Just one of our resent threads. I dont disagree with the intensity, growth & colour from halides but its not the end all of lighting. Certainly in many cases its the only way to go, but in others, T-5 or even vho, serve the purpose fine.

I agree and disagree (arn't you glad I am back ) I red that and didn't see anyone say T5's were better than MH, but if you remember a year or so ago.. "T5s are the best thng on earth and blow away MH set ups"

I woudl still like to do some measurments on them to see the intensity drop off on T5's compared to MH as all the tests I have see are done at 6" from the bulb through air type of thing. I have seen T5's in the fancy MH-T5 light set ups and when they are turned on you can hardly notice them.. I sat there thinking... "It looks like the water got more blue but I am not sure" now maybe they were a broad spectrum T5 but I realy wasn't impressed. Mind you I am looking at them for an option for my fresh water tank, and yes I think I would use them for actinic over PC and VHO just because they are popular so they are cheaper to replace now.

T5's do not compare to PC's because I've owned both. I couldn't even look at T5's without hurting my head. I wasn't aiming to turn this into a MH vs. T5 thread, that monster doesn't need to be raised from the dead. What I meant was that upgrading my PC bulbs to T5's would be a great compromise with changing out the MH bulb for a 250W. Much less work and much less $$ for results that would still be great.

and adding the T5's probably wouldn't be as supplemental actinic. Instead I'd run some 13k T5 bulbs to increase PAR because the 14k bulb is already nice and blue. I want just a little more PAR.

Oh and I have read some MH vs. T5 PAR measurements. They're hard to dig up on RC (they're out there) but the T5 6700/13k (50/50) measurements were across the board more intense than 250W 10k MH lighting when within 16" from the fixture. After 16" you lost light considerably. This is a 16" tall tank so T5's would be very intense in it.

This is a single tank scenario that I'm trying to solve that has a $$ budget. I'm not trying to solve the debate between T5 and MH

Is this for real? The T5 PAR measurements have been replicated numerous times on RC. Take a look at this thread - first page has a pic of PAR measurements IN THE TANK with a POS Tek fixture that isn't actively cooled (the increase in intensity with active cooling and quality reflectors has been shown to double the effective output of T5s): http://reefcentral.com/forums/showth...&highlight=par

I'd have to spend some time fishing for the other threads with PAR measurements of better quality T5 fixtures. Attempting to draw a comparison of VHO to a quality T5 is insane. The application of a quality reflector coupled with active cooling has repeatedly been shown to produce sufficient lighting to enable the highest light demanding SPS to thrive. As mentioned above, the effective output is nearly double that of a non-cooled lamp without individual reflectors.

If you need to measure it for yourself to feel comfortable, go nuts. I've also got an umbrella handy just in case you want to make sure that you can't jump from a roof in a magically contolled fall like Mary Poppins

Andrew.. what exactly does that thread have to do with T5's being better than MH or not

yes there were, and there were also IceCap claims that turned out to be false... problem is it is so easy to fuge readings with these sensors.. hell I can make a 100 watt light bulb put out more PAR than a 400 watt MH by only moving the sensor 1/2" there has also been a lot of debate about the way people were taking T5 readings... so no I don't put any faith in RC anymore.
