yes, the ambient air in the hood may be low but the temp immediately surrounding the bulbs is much higher,

Tim,
I have 2 fans blowing accross my bulbs (both IC variable speed temp fans)... The hood is vented at the bottom back with both fans blowing in from the back..... I don't know if it's the right design or anything, but I don't know what else I would do (other than maybe mount them at either end blowing in. Dave

i mounted one 4" fan on one side of my canopy, then used carboard to makes some oakey ductwork so all the air that the fan blew in had to go down the length of the bulbs in order to go out the exhaust duct. seemed to work quite well. as long as your fans are working properly, meaning the temp sensor is good, i have to IC variable fans

The fans are blowing out the center top of the hood with the back of the hood open ie. best air flow that way,
have a pic of the hood in my gallery if interested

looks good except i dont see the front t5s getting much airflow but unless they are super hot to the touch or are getting black rings around the ends then you are probably fine.

For those interested I've added a miscellaneous section to my website (http://www.danj.com/reef )
If there is an interesting piece of information I'll post a new topic here. Dave

The Icecap overdrives the 80wattT5s (5footers) to 100 watts. There are spec ballasts for the 80watters...Advance makes them...thats for sure...Advance makes everything! Lol. Im not sure of all the others that do...maybe fulham |

From IceCap:
zapata41 - " ... I have to IC variable fans A correction - When IceCap states wattage per lamp, the energy the ballast consumes, though small, is nevertheless included. Therefore if a Model 430 runs two 54-watt T5HO lamps Andy |

If you want the best radiation lumen/watts or par performance for your reef animals, it don't really matter on any brands of lamps
If you do not have a good meter, it is very easy to tell, put a new bulb of the same kind side by side turn them on You will able to tell the difference if the bulb is six months or older. |

T5HO GE 54-watter on an T5HO ballast will last up to 20K hours. For reef applications, 3 years approx. The 6 - 8 month rule only applies if you're roasting your fluorescent lamps (or selling lamps). It was once true of VHO lamps with cheap, conventional billboard application ballasts. In 6 - 9 months they could lose 30% of initial output.
New lamps will always appear brighter Andy |
