tek t5 vs ati??

khoivo1 · 10/08/2007, 06:54 PM

helo,,,i heard ati is a new line of t5 fixture,,so anyone know how much would it cost?? for 48x6x54w? does it run cooler than tek t5? i have a acrylic enclosed canopy just wonder if any of the two light will work better for my enclosed canopy,,any help here ??thanks

The ATI T5 fixtures are new to the US, they have been in Europe for a while. There is a tremendous demand for quality T5 fixtures (which the Sunlight Supply Teklight is NOT) and the ATI fixtures are only trickling in. If you want info you will have to contact ReefGeek and if you want one there is a waitlist.

The ATI fixtures run way cooler then TekLights since TekLights are poorly designed with no active cooling. The ATI fixture make DOUBLE the par of the TekLights.

Choose wisely,

James

do you know how much ati cost 48x54wx6? and how do i order ? thanks

Call or email greg for price and waitlist.

the ati powermodule is on a different shelf than the tek fixtures, IMO. Ati has superior build quality and light output to it. Runs cooler, looks cooler, frankly is cooler.

There are two different levels of ATI: the top of the line PowerModul with its good looks to go with its fantastic performance and the SunPower, which has the same performance but looks rather basic and costs much less.

"Double the PAR" that's a pretty big statement, what is this based on?
The Tek lights do have convection cooling which keeps the unit cool enough to touch even after 10 hours of use and keeps it completely silent.

jamesdawson · 10/11/2007, 11:16 PM

Well Chris,

The Grim Reefer here on RC has PAR tested many fixtures and he found that the TekLight made 152 and the PowerModul made 301. The PAR meter didn't lie.

In any case you should probably disclose that you work for SunLight Supply. I have not seen you guys around since you pulled your forum and your excuse of a rep Sam Remington was banned for repeatedly slandering and insulting many RC members and rival manufacturers.

Please give Sam my regards and let him know that myself and several others have kept alive your company's lack of concern regarding Sam's tirades here.

Hi James, I don't have a problem admitting that I work for Sunlight Supply, nor am I ashamed of it and I don't endorse ANY of Sams actions on RC.
I have been with Sunlight Supply for 4 years and have known the owner of the company for 12 years. I'm also not here to slam anyone or any company. The reason I questioned the "double output" is because the lamps being tested are T5 HO lamps which emit 92 lumens per watt (I know lumens is not the best measurement for this industry but this is how the lamp companies rate them) We are now using a 96% miro 4 aluminium reflectors in the Tek light and as always each lamp has its own individual parabolic reflector.
So when combined with the output of the reflectror its hard to see doubling the output even if someone is using 98% miro 4.
I have also witnesses the fan cooling affect. In the test that I have wittnessed the PAR levels somewhat balance out once the fixtures have been running several hours and lamp temperatures settle into place. I'm not saying this is law, but it's what I can say about the test I have witnessed in person.
I wish I had time to answer every questions you guys have about our products and chime in on statements that I think people should hear our side on. But I work 50 - 60 hours a week, have a family and do a lot of traveling for work.
Sunlight was on the forefront of T5 technology before everyone and there is LOT coming your way that I feel will put us as one of the leaders for the industry.
I appologize for such a long post but there is no one here to give everyone our side of the story. I have watched a lot of SLS bashing and thought I would atleast let you know we are not the company that a lot of members think we are. We and I are very pasionate about this industry. I'm trying to get the company to reopen the forum but there has been a lot of damage done. I make no promises.
Thanks for the time it took you to read this post and I will try a little harder to visit more.
If you have any questions please PM me.

'double the output' was determined from 'fishing around for the highest spot value'... as in, the fixture focuses its output more at some points. I dont think it can be taken as the fixture making 2x the output though... that would require a full grid test to determine.

As for Tek vs. ATI... thats a hard one.

The ATI has to have the sides and top open for its active cooling system. Also, half the reason for getting the ATI is the cool look of the fixture. If you plan on enclosing the thing, I think an icecap or Tek2 retro is a better idea, because then you can also add fans easier, and in a more effective placement.

The Tek's main sore spot is its lack of active cooling. T5s NEED active cooling. A passive cooled T5 bulb will diminish the same amount in 6 months as it takes an active cooled bulb to degrade in 18 months!!! This is as per my own comparison with the actual Tek fixture. Also, right off the bat, the active cooling boosts the output by about 20%.

Teks can be okay, but you have to add fans. The easiest way is to use the acrylic sheild, and then use a cross-flow fan attached to the underbelly of the sheild so it blows air across the bulbs between the acrylic and the reflectors. This doesnt even cool the ballasts as well as possible though... so there is still room for improvement.

Sam bet me a while ago that if he tested the Tek with & without fans and found a significant increase in output, all the new Teks would be 'active cooling'.

Upon losing that bet, then he backpeddled and said that an active solution would be offered as an 'upgrade' at some point. What a joke... you can add an effective active solution to a passive system. The passive ducting undermines the ducting needed to regulate an active system.

If SLS wants to take back the market with the next Tek, it should make sure there are fans in the unit to cool the bulbs & ballasts, include the sheild then as part of that system (to guide air over the bulbs, as well as keep the reflectors from staining so much). Oh, and keep using top-shelf spec T5 ballasts like the Universal/Advance/Sylvania/OSRAM/Vossloh-Schwabe models... dont skimp out and go with the Workhorse crap.

Cool. Guess I will add a shield to my tek and some type of cooling system.
