looking for a simple LED refugium light. I like the look of the clamp on the side type light like the picture below. let me know if you have something similar.

I purchased a cheap clamp on desk lamp for $5 on amazon.   Then a grow bulb separately for about $10. It works great.

It is possible that longing for something is actually better than having it. Satisfaction is the death of desire.

The value of the Home Depot Special is uncontested. It's been used for many years by many of the hobbyists here. Interesting that you would bring this up today. I posted this just last night for another hobbyist.

Wink The HD Special is so named because the clip-on cone reflector and the highest wattage "Daylight" color twist PC/CFL bulb (abt 30 Watt) can be purchased at a hardware store for about $17. Get the ordinary twist PC bulb, not the flood light and make sure it is the Daylight color because it is the best at growing Refugium algae."

Aloha,

The lighting over Macroalgae in a Refugium needs to be very bright and a broad spectrum that is more blue than yellow. 

Coincidentally, I needed to set up a Refugium today so I went to Home Depot.
The Aluminum Cone Reflector is just $8 
A 4-pack of 23 Watt (100W incandescent equivalent) Phillips brand "Daylight" color (6500 Kelvin) bulbs was less than $10

These bulbs are rated to last almost 5000 hours. Run 12 hours/day that's about 2 years . Going by that rating, I got 8 years of lighting for this client Refugium for just $18Big smile Of course the bulb will be switched out after a year or so, as they do lose intensity, so I'd have to say that $18 bought me about 5 years of lighting for this Refugium

Unfortunately Home Depot is hardly carrying any twist PC bulbs anymore. The other "daylight" color twist PC bulb they had, EcoSmart, was rated as 5000 Kelvin. That's too yellow. I also noticed that consumer lighting in general is switching over to LED's enclosed in bulbs. Not only are they more expensive but they are not the right color. Again, too yellow. So what if they last longer. Tongue

Here are a couple LED Refugium lights I have dealt with:

- Wavepoint Blade - 12 x 1 Watt 6500 Kelvin LED's. Price - $50
- Innovative Marine Skkye 6 x 3 Watt 8000 Kelvin LED fixture. Price - $129

Of those two, only the Skkye fixture rivals the light intensity of the HD Special. Smile

Aloha,

That's half the light energy (6 x 1 W LED's) as the Wavepoint Blade but, assuming the magnet can go underwater, if mounted on a clear space on the back sump of an AIO tank, just a few inches from the Macro, that would be a very effective light for that application.

I know I'm a crazy hobbyist, because I always look at the cost benefit ratio or in this case the $/Watt. 
Innovative Marine MagnaFuge - $50/6 Watts = $8.33/Watt
Innovative Marine Skkye - $129/18 Watts = $7.16/Watt
Finnex StingRay LED Clip - $26/4 Watts = $6.50/Watt
Wavepoint Blade - $50/12 Watts = $4.16/Watt
HD Special - $18/~18 Watts (similar energy as the Skkye) = $1/Watt
p_hefe suggests a fluorescent(?) that is probably in the $1/Watt range as well

This hobby does not have to be so expensive and, backwards32 did ask for a "simple refugium light", right? Smile

Yes I am trading someone for some frozen food so the light I am getting is $0/watt. Haha thanks for the idea though mark.

I'm not sure when Webster changed the definition of simple to the cheapest. I'll have to research that.

Simple to me means: Easy to mount/remove, not a lot of parts, reliable and long lasting, No tools required.

I'm just going to play the devils advocate here for a minute on this as I think if Mark is going to explain why he goes with the cheapest option, I should also touch on why some people would not go that route. This is not disputing that the HD special works and will grow macro. However, I have seen a significant trend in this hobby toward systems where the sump and filtration areas are just as clean and tidy as the display. So aesthetics play a huge role in these setups. While the HD special may work, it is not a pretty look and is quite bulky. The other trend I see is to replace high voltage devices around our aquariums will lower voltage DC devices to reduce the risk of shock. I've found the squeeze clamp mount to be quite hard to get to hold in a reliable way with the plastic trim on most sumps (Whether it's a tank turned into a sump or a more expensive manufactured sump with top bracing). I also find the galvanized metal used in the squeeze clamp and adjustment arm to be less than ideal in an area where salt spray is almost always present.

So does it work? Yes.
Is it pretty? No
Is it risky to have a less than ideal mounting system holding a high voltage electrical appliance over a water filled tub? YES!
Will it rust and corrode quickly? Yes.
Is it UL listed for use in close proximity to water? No.
Is the light designed for the purpose at hand? No.
Is it easy to get? Yes.
Is it inexpensive (read this cheap)? Yes.

I'll see if I can find any reference to simple meaning the cheapest option. My quick google search returned zero results.

I am going to chime in here with the fact that Mitch asked for a simple LED refugium light and even posted a picture of the type of light he is looking for. I also agree that the cheapest way to do something is not necessarily the best way.

I wanted to illustrate my point a bit more. This is the picture Mark shared. Not a bad setup and I'm sure it works and does what is intended. It's probably not a focal point of your reef or something that draws as much attention as the display it's connected to.



My own version. As Adam will attest it is almost as cool to look at the sump as it is the display. I think he took more pictures of the sump while on the reef tour than he did the display.



Can you find the LED refugium light in my sump? It's the small black box between the skimmer and the reactor body. I'm pretty sure I could not fit an HD special in here and if I somehow found a way it would definitely detract from the enjoyment of looking down here.

haha you guys are funny. There are many ways to skin a cat. I will admit I have in the past done the setup that mark is describing but as discussed was not happy with the look and functionality.

here is what I ended up going with and I feel is simple yet looks nice and I feel will grow some good algae.




to each there own I guess haha

Man, look at all those loose wires in the back...what a mess and how embarrassing...you better clean that thing up! Geez, some people are such slobs.

Good points above and good discussion. I agree with using what works for the application. I am coming from the angle that the Refugium will not be shown off to visitors, unless they ask.

Yes, the HD Special can be inconvenient to clip on. I have clipped it to plumbing and to parts of the stand. Other times I have discarded the clip and simply hung it by the cord. I've put grabber screws into the stand above the Refugium. It's a very light weight fixture so there is no electrical danger when hung by the cord. 

One important safety step for the HD Special is to use a Zip Tie to secure the clip and/or the cord so there is no risk of the light falling in the water. 

As far as corrosion, that's not a problem. The clip-on cone reflector is light weight aluminum. It lasts a long, long time. Like any Refugium light, salt spray needs to be cleaned off periodically.

Today there are so many more options available to us than when I got into the hobby. Back then almost everything was DIY. Even with all the options I still choose to consider the equipment that does the proper job at the lowest cost. 

The Refugium can be a critical part of tank filtration. I sometimes wonder if some hobbyists don't realize that if the lighting is bright enough, the algae should almost double every month or two.

Aloha,
Mark  Hug

BTW, this was the entire system, the floating reef, with beautiful Blue Spot Ribbontail Ray and Batfish. Nobody cared what the Refugium looked like. LOL

I've always used the HD special, except on my new tank. I wanted to get it completely out of the way and I didn't want to spend much, so I made one myself. It consists of one 10w cool white, three 3w blue, and two 3w red. It works really well and grows macro throughout the whole 29 gallon sump with exceptional growth in the center. It ended up being about $1/w.
I look at my sump often and love to see all the life in it.
