How about hooking up a cheap solar panel and charge up a deep cycle battery to power those lights? Looks like even the stirling engine could power it. The music is ok but I'd rather have you explaining things.

If you want cheap prices go to eBay. Also order them from china if you don't mind waiting 10 days. You will see that the same led sold in china is the same sold in the us. But us prices are double to triple for les quantity. Just take your time looking for the right led. For example I upgraded all my trucks lighting (except driving and fog lights) to led and I payed 20-25 bucks for all. Same stuff here would have run me 60-80.

@CalicoatMaker - Get yourself some silver based solder? It melts a slightly lower temp and the joint is much more reliable and has a lower resistance. Maplin sells it.

@JesusFknChrist666 - most 'white' LEDs emit no red. You need red and green light for plants however. Most LEDs are blue-white. I would add a few high bright red LEDs in the mix.

Are there LEDs specifically made for plant growth, or does the color of the diode itself emit the proper spectrums suitable for vegetative and flowering purposes? I hear they're great for growing "medicinal marijuana".

Nice video. I like the4 light system.

@gilberda idiot. LEDs cost about 3 cents each.

@CalicoatMaker Power factor and harmonics is a serious issue, any inductive load (including switch mode PC power supplies without correction can be undesirable.
This looks to be a 16 LED device in this video, I have no specs, this was a generalization about White LEDs.
LEAD-FREE solders melting point ranges from 423°F to 439°F
Traditional electronics (non ROHS compliant) solder is 63Sn37Pb and melts at 361°F
Regardless proper heat sink is required where needed
None beat the SUN for lighting

@CTOL1 CFLs introduce harmonics in your entire branch circuit. I cant risk data corruption,so I went back to incandescent. My electric bill was $2 more the next month.
Most of the energy used in a home is not the lighting anyways.
As far as LEDs producing heat, you wont get measurable heat from a 20mA/3.5v LED. Ever. I*E=P [or W, really]. Thats 0.07 watts. Vid shows 2.0 watt
The problem with LED lighting is heat making the solder joints come apart. Lead-free solder melts at a VERY low temp

Chocolate Bunny Melts Under Incandescent Light, Survives LED Lightby CreeInc50,756 views
LED's are very expensive in stores and designs are very limited. Search ebay... I've purchased the exact 3 led screw-in type that's 29.99 at Home Depot for the awesome price of $20.00 + S&H for 5 of them!!! Not 1 but 5! They're on 24/7 outside since Dec. 2009. The bright white light is ideal for safety lighting. I use other models in different areas all purchased on ebay because stores charge too much these! The savings on electricity are totally worth it! Thanks for your posts and God bless!

@gilberda our new link page has some cheaper places. I just placed it in the more info section on this video.

Without a current control device you will pop them, or severely shorten their life, then there is the heat they create. Much like a processor in your computer if not bonded and heat sinked, you will destroy it. Most LED's require about 3.5 volts and limited current of 20 Ma per lamp. The best controllers use pulse width current limiting, but it can be done with proper resisters Pulse width usually offers dimming features.
Don't give up on the compact fluorescent just yet, there just $1.00 a pop

@CTOL1 Where is a good source for a control device? This one came with it but I was looking for the independent.
