The T5 Q&a Thread

[dc_909]

Hey Grim,

Could you explain PAR and PPFD to me? I show you use PAR for measuring T5 bulbs ex. ATI B+=311

Sanjay uses PPFD for halides ex. Iwasaki 15k=71

How do you convert PPFD to PAR? or are they the same?

Hey Grim/others, I'm running 8x54 watt T5s, could you send me a PM about what bulb combo i should go with? Thanks

Depends on what you are trying to grow, what equipment you are running and the dimensions of the tank.

We are measuring the same thing it is just the method that is different. Sanjay is not using reflectors and is just mounting the lamp in a sealed box. I am measuring in a functional reef tank.

PPFD is measuring the PAR over a given area by taking numerous readings and reporting the total. That is really helpfull as far as knowing how a reflector desperses light but you need a fixture to do that. I just take a single reading.

Okay, probably a dumb question. So two each of the bulbs listed in that order? Since there will be 4 bulbs per 660. Then would you have the front coming on first and going off last? I was thinking of alternating the bulbs front to back on each ballast to distribute some of the heat on the bulbs.

Thanks

I am not familiar with a lot of those. I think this could be nice but I would try posting on some european sites to get opinions of peole who have seen all of them. The Narva Blue is the Geisemann Actinic Plus. I have seen the output plot for the AS 15000K and I think it is more of a daylight than 15K but it looks promising.

Thanks Grim.

So if Sanjay does not use reflectors and the PPFD is 71. If I have reflectors in my setup the PPFD will be higher?

 

[Roland Jacques]

What is the web site for Sanjay info that everyone refers to??

Do this instead http://www.customaquatic.com/customaquatic/itemdetail.asp?itemid=LT-CV-T5RK2-2

They have moisture resistant endcaps and parabolic reflectors.

Thanks for that link. good for MH

I found this one, i ODNO t-8s so it was helpful to me. Are their any more lamp comparasion links for floresent bulbs?

http://www.aquabotanic.com/lightcompare.htm

I guess it will be a while before t-6 vho are tested thourghly. i heard the 48" 110 watt lamp are about double the par of the HO 54 t-5.

hit reefgeek.com and get some good lamps. Use 2 GE daylight 6500K's, 1 ATI Aquablue, 2 Blue Pluses and 1 UVL Super Actinic. You think you have growth now

Hey Grim! Me again!

I do not see any blue pluses on the website. There are some 11000 k aquablue pluses from Geisemann. Are these the same thing?

Thanks again!

Actinic Plus would be about the same as Blue Plus.

GREAT LINK!

The VHO T6 is not quite double the output of a T5 but it is in the neighborhood.

 

[outtreking]

Would I be better off with the blue plus? I could possibly find it somewhere else?

Thanks again Grim!
