A great refugium lightbulb, IMHO!

[melev]

Anthony Calfo recommends the rolling action. I've had it growing stationary for the past couple of years, and even the part that is at the bottom is bright green when I lift it up to see how its doing.

 

[Abalone joe]

So the recomendation is only to ensure the entire algeal mat recieves adequite light?

 

[cgh38]

melev,is lumens an important factor? I noticed that on this bulb that Prop-Frags posted http://www.bulbs.com/products/product_detail.asp?page=products&inventory=12598
the lumens is 1200 compared to the bulb that your'e using at 950 lumens for the 19W bulb.
Thanks

 

[melev]

I don't know much about lumens. I care about Kelvin, and to some degree PAR. PAR is the intensity, not that I have a way of measuring it myself.

Marc,
I've been having red algea problems in my fuge using this bulb. Has anybody run into this problem? My sump and main tank are fine, it just the fuge that gets covered with it. Any help is greatly appreciated.

Thanks,
Steve

I have as well...a fine, fuzzy red algae that grows on the glass walls and baffles in small clumps...only in my sump, not in the display. My bulb is pretty old though (8-10 months; not sure), and I was wondering if that may have something to do with it.

 

[steveoutlaw]

My bulb is about the same age. My fuge is also exposed to the light from my main tank. I wonder if this has an effect?

Mine not...mine's isolated from ALL other light sources for 95+% of the time.

The "Red Algae" may be cyanobacteria, i.e. Red Tide. How are your phosphate levels? Phosphates are great for growing cyanobacteria.

 

[TA]

Its not cyano.
This is an alga...not bacterial.

Wow, it took me more than 3 hours to read the whole thread in a run.

Thanks melev!

Well I can report that my chaeto has not done well. I think it may be dead. It's looking very brown and has sunken to the bottom. If I stir the water ever so slightly, it floats/flies around everywhere. It's back to the drawing board for me. I'm going to try to find the light melev mentioned.

Guys, I did a search but only found one mention of the Philips Agro-Lite in another thread. I bought one of these at HD today along with the clamp-lite reflector. I can't find any data about this light other than what's on the box. The Philips site says it's unavailable. Maybe my HD just has lots of them leftover. Here are the specs I have from the box:
50w Agro-Lite Plant Light 120V
"For the Acceleration of Indoor Plant Growth"
2000HRS Avg Rated Life
Standard Base
R20 (2-1/2" Diameter)
Can't find anything about the actual kelving rating.
Has anyone used this light?

 

[sales weasel]

So how have these worked?

i sure am

 

[greg10]

That is great news. it sounds like sales weasel didn't have much success with it.

Please dont take this as a slam but maybe i can help a little here, PAR is acually the size of the Bulb, (though in some applications like home lighting, companies will tell you that Par is the Intensity) Lumens is the accual output of the bulb (Intensity) and Kelvin is the color temperature. I havent acually tried it on an aquarium, but you can place a filter (GEL) on your bulb that will change the color temp to the desired temp. Gel can be found at any production house in your town or can be ordered from www.internetapollo.com or leefilters.com. It is fairly inexpensive and you would get roughly 8 -- 10 cuts out of a sheet. You would have to replace the gel ever once and a while as it will burn thru after prolonged exposure. Let me know if you would like more info. I dont know why i never thought about doing this, it could make for a very inexpensive DIY sump light Cheers.

PAR is also used as an acronym for photosynthetic active radiation, or something like that. It refers to how much of a lights output actually supports plants.
