150W dome light too much?
    #7556844 - 10/24/07 08:31 PM (16 years, 5 months ago)

Yea so I was planning on equipping my FC with a 150W (about 2.5" in diameter) light, or possibly two. I am aware of the fact many say you only need so much light and I was planning on keeping it on an automated system with a timer to regulate light times. My question is:

Is 150W (flourescent) pushing it? Is this too much power or not enough and two would suffice?

Feedback please; thanks.:thumbup:

should be fine, unless it gets to hot.
What spectrum is the bulb?

I'd say that it's plenty. There's no reason for two unless you're talking about different layers of shelves. Just be careful about the heat.

One is defentally enough, I only use a 40w and I get pretty great pinning.

What kind of fluorescent bulb is 2.5" in diameter and consumes 150 watts? I've never heard of such a thing.

It's a compact florescent not a tube florescent.

I think he is confused. He must mean a 45 watt tube that emits the same output as a 150 watt incandescent bulb. As far as there being a fluorescent tube that requires consumes 150 watts..... There is no such animal that I am aware of.

Ohhhh. A CFL bulb. I get it now! yea, those do go all the way up to 250 watts I believe. The sure are expensive as hell! I use them in the restaurant I manage.

Yes, sorry I did not mention. Thanks for the feedback everyone :smile: . Yea I do fruit in a slightly small area and between the fan running FAE on the top and the filter, the light's compact size is ideal for my situation.

That would be an awesome 2.5" tube light, youd have planes landing in your back yard!

I've still never seen a 150 watt cfl that small. At any rate, with multiple shelves or long shelves, tubes will spread the light out better, thus giving more coverage. I use 5 shelves in my mini-greenhouse, with a 48" fixture hanging vertically in front of the unit, which holds four fluorescent tubes with a color temperature of 6,500K. By hanging the light fixture vertically, the fixture lights the entire greenhouse between all shelves. With only one bulb, you're limited in coverage. They'd be great for tubs and the like, but there is no need for 250 watts. It will burn five or more times the electricity your projects require.

This post has me a little concerned ....

I am currently ordering a couple of compact fluorescent bulbs .... little spiral, screw-in guys .... and I'm trying to decide what wattage for a 30 gallon tub.

The 15 watt mini spiral cfl is equiv. to a 60 watt incandescent bulb. The 20 watt is equiv. to a 75 watt incandescent, and the 24 watt mini spiral cfl is eqiv. to a 100 watt incandescent bulb.

I was figuring the 15 or 20 watt would be plenty for the tub. ?

150 watt ? really?

Either one will be fine. When they say equivalent to a certain wattage incandescent, they're talking lumen output, not color temperature. Fluorescent lamps are far superior as far as putting out the correct color spectrum for fungi over incandescent lamps, which emit a red light at 3200 Kelvin. Try to find one with a color temperature of 6,000 to 7,500 Kelvin.

RR,

Thank you.

These little mini spiral screw-in bulbs are 6500K.

$5.49 each online through 'Bulborama' ..... $9.50 flat rate shipping. So ..... I guess I'll buy a few of them.

I was having trouble finding 6500K screw-ins at Home Depot etc.

They say the cfl don't put out much heat. If they are inside a FC, is humidity a problem? Up until now, my light has always been outside the FC.

Thanks.

Sorry for jacking the thread.

The light should be outside the FC. Check grocery stores as well as hardware stores. You should be able to get them without paying shipping charges.

Geeeeeeeez!

I must be retarded !...... or I don't get out enough ......

I walked over to Walmart and there are tons of 6500K cfl spiral bulbs.

Got a two pack for $6.33 ... $3.17 each and no shipping ...

I did see a 150 watt = 42 watt bulb .... maybe this is what was originally referenced.

I purchased the 26 watt = 100 watt bulb and will mount it to the outside of the plexiglass FC top with a shield/reflector to protect the bulb and to direct the light toward the top of the casing surface. I remember a post (maybe yours) stating, "light intense enough to penetrate 1/2" casing layer ..."

Just curious .... what is the difference between placing a fluorescent tube in a greenhouse and placing a cfl bulb in a FC (separate cased trays with plumbed in FAE and humidity)? Wondering.

Thanks MAN.

Pinnie ... sorry again for jacking your thread.

None. Both are bad ideas. The light needs to be outside where it will stay dry.

Thanks RR, and everyone else. No worries uncle_rico, I appreciate the extra information thriving throughout this thread. In addition to the suggestions, I was, however, looking at the equivalent of a 10" tube light that comes encased except this is a few bucks more. I will probably end up going with the tube light as it disperses the light a bit more and will probably be more plausible towards the dimensions of my FC (rectangular nonetheless).

    In reply to the post above I am personally going to start mine out at 6 hours tops daily skipping one day (probably Thursday) out of the week. I will probably drop it down to 3 hours the following week and decide from there. Try not to consider my advice from a professional standpoint as I still have much to learn in this mycological field myself. I can help you by saying, following along the knowledgeable RR or many of the other shroomerites amongst you would put you on a better path.:thumbup:
