Personally I would stay away from DIP style LEDs (ie: the kind you solder to a breadboard) and other individual LED components. Using individual LEDs and resistors will involve a large amount of legwork that will be both a major headache and waste of time. DIP LEDs are also less energy efficient than SMD style LEDs which offer far more brightness and come pre-soldered to a PCB with the proper resistors necessary for 12V DC input.
If you ask my opinion, I would say just go with the LED super ribbon. It's very noob-friendly and overall the best product for the job. The cost might be higher (roughly $7.50/foot depending who you order from) but if you're going to go the LED route, it will pay to go with the brightest product on the market versus experimenting with other, dimmer products. It will also pay to go with something pre-assembled on a PCB; let's face it, time is money.
If you only need enough LED lighting for one terrarium, you could ask Orient Lighting (or another LED lighting company) for a short sample piece of waterproof super-bright flexible ribbon. You can probably buy a 2' section for around $30, and if you ask them to ship it via Air Mail then the shipping cost will be a lot lower than a typical courier delivery.
PS: Whatever you do, always buy your power transformers domestically, like at Radio Shack or DigiKey or something. If you live in the USA you must use a UL listed power supply, in Canada it must be cUL or CSA approved. Most transformers that Chinese LED lighting suppliers sell are only CE approved and not up to North American standards. As such, if you use a power transformer from China that's only CE approved and it happens to catch fire, your insurance company will not insure you. 
So for that reason, ALWAYS make sure you use a UL listed (if in USA) or cUL/CSA approved (if in Canada) power transformer with your LED lighting and you'll be good to go!

I have had some experience in electrical engineering and I compared the lumen output of the strip and the ones I linked and there wasn't much difference. The ones I linked already have a resistor soldered on and they are triple shrink wrapped to a wire. I will still add some electrical tape but the whole reason I wanted them is so I could do an experiment by drilling holes in the lid for the wires and hanging them a few inches above the substrate. I have an extra ATX power supply to power then since they are 12V plug and play.
I just want to see if the mono with the lights closer to the sub does better than the one with 10x the lumens with cfls. Pretty much just bored...

That site everything is free shipping and I hate eBay, half the time I order something from a top rated seller they don't send it.

The pre-soldered ones may be good for an experiment, hanging the LEDs a few inches above the substrate like you mention will definitely increase the amount of light the mycelium receives. As the fruits develop you could pull up the wiring a bit to raise the lights, keeping them above the canopy.
I don't see the color temperature or brightness listed anywhere on the pre-soldered LED page. When placing the order you should confirm with the seller to ensure they are the brightest 6500k LEDs they have.
I will admit I am a bit biased towards going for the ribbons because I have a lot of experience with them. My monotubs and MSGs that use internal LED lighting have been producing quite nicely for the last few months.
Soon I plan to set up a few more monotubs for some new strains I recently ordered from a site sponsor. For my next lids I'm going to order the LED strips pre-assembled with a DC power jack on either end, so each lid will have two power jacks. I'll connect a 12VDC 5A power adapter to the first tub, then daisy-chain one to the other. One adapter can power six 14-gallon monotubs or nine mini-MSG's.

exactly what I was typing about earlier in my super long post, see if the amount of light in a solid tub lined with an emergency reflective blanket that you get from an emergency kit that costs like $2 and have your whole tub like a mini greenhouse shape and put a free paper funnel covered in waterproof tape to the hole inside on the drip roof.
Then you just drill a few more holes for the wires to the strings you hang them from, screw drilling holes in the lid, I might use my fan idea with one. I am going to go measure it out for my tub and get an emergency kit from the dollar store.
You put the blanket in before your black bag. I am going now to measure and draw on paint.

I was planning on using this http://besthongkong.com/product_info.php?cPath=5_33&products_id=509 and filling it with these http://besthongkong.com/product_info.php?cPath=19_46&products_id=492 Have the resistor on the diode taped down because their wires bend easily and have the wire sealed with heat shrink wrap like they sell the crappy ones.
I figure that being a few inches above will be enough to widen the view angle enough to cover the tub because the higher you go with them the wider the angle and the less light will be shining on them, I will go draw one since I don't have an emergency kit. The emergency kits are the ones that have the fishing line, hooks, matches, and bandages and such for hunting and camping. You can get them easily and that blanket is like a mirror and super thin.
If your lights were in the tub you could just decorate it by a window somewhere with a doily and a lamp or something. I am getting closer to a tek, I can feel it. LMAO I am crazy, its pretty bad when you can tell that you yourself are a complete loon
It would be very stealth.(the mylar blanket cut to size taped to the tub, to block the light, keeping the tub from glowing so bright and reflecting the light)NM might have to do away with that unless the top exhaust holes would release enough of the heat to keep it under 81F in there.

I would do it with these http://besthongkong.com/product_info.php?cPath=19_46&products_id=492 and make it something like this in a solid color tub with an emergency reflective blanket taped to the walls. Then just raise them when it started pinning. They can be up to 585 lumens depending on what resistor you use and what you hook them to and how you hook them up, that would be like having 4 100 watt light bulbs inches from your sub with almost no heat using 10 of them. You just use the right resistor since you would be hooking them up parallel to a cheap 480 watt PSU. The resistor would determine how many amps it got from the 12V PSU and raise or lower the color temp and the lumens. I would like to run it at 10000k just to see if it would pin.

Leds determine their color temp by how much current passes through them, you have to know the view angle and the mcd of the LED and then use a formula to estimate what spectrum it would be at a certain amperage.
candela (millicandela) to lumen conversion wizard This calculator allows you to do an approximate conversion between millicandelas (or candelas) and lumens for an LED where you know the beam angle. The reason it's approximate is because the specs don't usually include information about how the luminous intensity (in candelas) was measured. This calculator is perhaps most useful in comparing the light output of LEDs with different beam angles.
To briefly explain the math the wizard does, it simply applies the conversion 1 candela = 1 lumen/steradian. To do this, it converts the beam angle you supply into a solid angle in units of steradians.
The likely thing for a manufacturer to do is to list their luminous intensity spec in the most favorable way possible. So it can be the case that this wizard provides inaccurate values--this happens because the assumption in the wizard is that the luminous intensity value you supply represents an average value across the beam angle you supply. It's too tempting for the suppliers to list a maximum value instead, since there is not a standard for measuring this. Beware especially of wide-angle LEDs, which will probably be distorted the most by this calculation.
luminous intensity (millicandelas) "825,000" beam angle (degrees) 55
Approximate luminous flux: 585.694 lumens
As a point of reference, a standard 100W light bulb typically is rated at around 1,700 lumens in North America, and around 1,300 lumens in 220V areas of the world. Certain special purpose lamps have lower lumen output as well. The brightness and the color changes with amps.

That statement is not true about most LEDs. Most LEDs are designed to operate at a specific voltage and draw a specific amount of current. Bumping up the voltage may change the LED color a little bit, but this is ill-advised and will drastically shorten the life of the LED itself.
Are you talking about color-temp adjustable LED strips? There are LED ribbons that are made to be color-temp adjustable by alternating 2700K and 6500K LEDs in a pattern, on two different circuits. Applying power to the 2700K circuit allows for 2700K light, and vice versa for the 6500K circuit. By running both at the same time it's possible to achieve light in the range of 2000K - 12000K. You can find these strips here: http://orientlighting.com/products.asp?id=145&SortID=32
There is an important distinction between those strips which use multiple LEDs of different color temperature versus LEDs which are not designed to operate at other color temperatures.
Also, if I were you I would avoid the mylar blanket. Reflecting light off the sides of your terrarium is overkill and will likely achieve nothing. You will also be impeding air flow (assuming a SGFC or mini MSG design) which will hamper growth.

LED Parts
LEDs come in all shapes and sizes, but the 3mm T-1 or 5mm T-1¾ are the most common.
The die is a small cube of semiconductor. The composition of the die determines the color of the light given off. The die sits in the top of the die cup, which is a reflector to reflect the light emitted by the die. The beam angle is determined by the shape of this relector. The epoxy body also is shaped to acts to effect the focus and appearance of the the light beam. The distance from the die cup to the domed end of the lens determines how tightly focused is the resulting beam of light. Some LEDs have flat, opaque, or even concave ends to help disperse the light into a wide beam.
LED Color
Visible LEDs
Wavelength/ nanonmeters = Color Name Color Sample over 1100 Infrared 770-1100 Longwave NIR 770-700 Shortwave NIR 700-640 Red 640-625 Orange-Red 625-615 Orange 615-600 Amber 600-585 Yellow 585-555 Yellow-Green 555-520 Green 520-480 Blue-Green 480-450 Blue 450-430 Indigo 430-395 Violet 395-320 UV-A 320-280 UV-B 280-100 UV-C LED colors are often specified in "nm", or nanometers, which is the wavelength of the light. The wavelength given is the wavelength at peak output. LEDs are not perfectly monochromatic, but rather produce a range of wavelengths over a small region of the spectrum. The graph on the left shows color vs. intensity for a typical green LED. Notice the peak is at about 565 nm, but it is actually emitting light over a range of about 520 nm to 610 nm. Spectral line half-width is the width of this curve at 50% intensity (0.5 on the Y-axis). For this LED, it is about 30 nm. Spectral line half-width is a measure of how "pure" (monochromatic) the color is.
Notice the temperature (Ta) given in the upper right corner of the graph. LEDs emit slightly different colors at different temperatures. They also emit different colors at different currents, especially white LEDs which depend on phosphors to change the colored light of the die to white light.
This is why white leds (in particular) will never match perfectly in color.
Infrared LEDs
The infrared band can be divided into Near Infrared (NIR) and Far Infrared (IR). Far infrared is the thermal infrared used to detect hot objects or see heat leaks in buildings, and is way beyond the range of LEDs. (NIR can be further divided into two bands, longwave and shortwave NIR, based on how film and CCD cameras react.
Infrared LEDs are sometimes called IREDs (Infra Red Emitting Diodes).
Ultraviolet LEDs
Ultraviolet light is divided into three bands: UV-A, which is fairly innocuous; UV-B, which causes sunburns; and UV-C, which kills things. Most UV-B and all UV-C from the sun is filtered out by the ozone layer, so we get very little of it naturally. LEDs emit UV-A.
400 nm is a pretty common wavelength for UV LEDs. This is right on the border between the violet and ultraviolet, so a significant portion of the light emitted is visible. For this reason 400 nm UV LEDs are sometimes rated in millicandela, even though as much as half of their energy is invisible. LEDs with lower wavelengths, such as 380nm, are usually not rated in millicandela, but in milliwatts.
YOU SHOULD NOT STARE INTO ANY LED DUE TO ITS BRIGHTNESS. MOST LEDS WILL INVOKE PAIN TO THE EYE TO WARN YOU TO LOOK AWAY. ULTRAVIOLET LEDS ARE PARTICULARLY DANGEROUS, BECAUSE A LARGE PORTION OF THE RADIATION EMITTED IS IN THE VISIBLE RANGE. THE RESULT IS THAT YOUR EYES WILL NOT INVOKE PAIN TO WARN YOU THAT THEY ARE HARMING YOUR EYES.
White light is a mixture of all the colors. Color "Temperature" is a misnomer and is not understood by most people. This is not helped by all the false advertising and hype that is used by marketers to sell their products. Color "Temperature" is a measure of the relative amounts of red or blue light being emitted. It is not a measure of temperature at all.
Higher color temperatures have more blue. A higher color temperature, is not necessarily an indication of a higher quality, or more expensive light. It is not a brighter light. If you want super high color temperature, just buy a blue light. It is has infinite color temperature which is higher than any "super or hyper" white light.
Kelvin Color Scale
Color Temperature Common Example 2000° Gaslight 2470° 15 watt incandescent bulb 2565° 60 watt incandescent bulb 2665° 100 watt incandescent bulb 2755° 500 watt incandescent bulb 2900° 500 watt Krypton bulb 3100° Projector type filament bulb 3250° Photo Flood 3400° Halogen 3900° Carbon arc 4200° Moonlight 4700° Industrial smog 5100° Hazy weather 5500° Sun 30° above horizon 6100° Sun 50° above horizon 6700° Electronic Flash 7400° Overcast sky 8300° Foggy weather 30,000° Blue sky
