2-ft Lighting Hood

[Happy Reefer]

Hi, this afternoon, my 2-ft light hood has caused by home circuit board to trip twice, so the tank light is now switched off.

This happens about 2 weeks after I earthed (change 2-pin to 3-pin plug) the light hood as previously I felt electric current in the tank water.

Looks like there is really some electrical leakage from the lighting hood.

So I need to change to a new one.

Need recommendation on any good brands of 2-ft light hood.

Does any such light hood comes with in-built fans and cover so fish won't jump out.

Should I look for lighting hood that fit T5 or T? light?

And should I look for lighting hood that can fit 4 tubes of light?

But then again, having fully covered hood may increase tank water temp.

FYI, currently, have some LPS corals and fishes.

Please pour in your experiences and recommendations.

Thanks very much.

Actually a hood is not really necessary.

Get some T5s from HV or DE that suits your tank and your $$

What is HV or DE. Pl clarify.

Pl also provide location of outlets.

Thanks

Thanks for your advice, Veliferium.

Yes, it does saves me a lot of money.

DE in short for DE Lightings

Hi Happy Reefer, sorry to hear your plight.

Lighting are often the source of leakage and shortage in our hobby. Especially when it is difficult for us to differiate the quality of the product through our ###### eyes.

Luckily for us, we have sponsors that provides quality product at a fraction of the cost of a imported light set. Contact DE or HV, I'm sure they will be more than glad to assist you.

Thanks Gouldian,

Surprised you still have time to surf the net, yr baby is a good boy, huh!

I have a kind reefer that helped me to install some T4 lights.

Understand that T4 lights are brighter.

Besides being brighter, can you tell me more about T4 lights (the blue and the white one) and the differences between T4 & T5?

(Want to learn more about these lights).

Thanks in advance again.

Hi Happy Reefer,

Glad to know you have a kind soul willing to help you with your lighting problem.

From my limited knowledge, most of the T4 in the market are manufactured for commercial lighting rather than Aquarium. Thus, you will find that they are usually available in 3000k (warm light) to 6400k (Daylight) which is alright for most commercial applications of illumination. Some of the tubes are dyed Green, Red and Blue for aesthetic reasons.

However, these lights are not enough for Corals that depends highly on photosynthesis for growth and food.

Thus if you intend to use the T4s for the illumination of your tank so that you may see the fishes and maybe support some hardy corals such as bubbles that dun need too much lights. I would think it will suffice.

But if you are thinking to use the T4 to sustain light demanding corals such as SPS, some LPS or even clams; I wouldn't bet my last buck on it.

Hope that helps.

Oh! Brigther doesnt' mean better for coral ?? (assuming T4 is brighter than T5)??

Would you suggest that I change the three T4 lights that I have to three T5 lights (2 blue & 1 white)?

Thanks.

T4, T5 or T8 represent the diameter of the tube the smaller the number the smaller the tube.

We cannot tell the brightness just checking whether it is T5 or T4.

The lights that most of us use are T5 HO. HO = High Output, thus you will notice a 2ft T5 HO will be rated 24W while a normal T5 may only consume 18W.

Further to wattage, we also need to know what spectrum the lights are running in.

Below are the spectrum most reefers use:

1) Blue Spectrum Peaks at 450 nm. Supplementation Lamp encourages blueing in SPS coral, minor fluorescing.

2) True Actinic Peaks at 420nm. Brings out the flouresce in corals

3) Full spectrum 6000k. For growth.

Hope that helps.

Thanks very much, Gouldian.

You have been most helpful in enlightening me on lighting issues.

With kind regards.
