HIGH POWERED LED 2 WATT x 3 in series 6 WATTS Efficient Green Lighting

[modeyus1984]

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.

[JesusFknChrist666]

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".

[ProfStuartHalliday]

@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.

[comoloco247]

Nice video. I like the4 light system.

[theonethatgoofs]

get cheep led lights from christmas strings . cheeper then radio shack . by about 150 fold

[dzgfdg]

yeah well....Chuck Norris can bend light

[garagecrap]

You really need to measure the consumption to find out the true wattage, Some of these led lights get as hot as a normal light bulb which in it's self can tell you the current they take.

[zaxtor]

Is funny when Diode LED doesn't produce heat but high powered led become very hot. as hot as a normal bulb.

Btw nice vid.

[brankaft]

@zaxtor thats what i was thinking.. high powered leds become hot so fast. thats the negative side of it.

[ilyass2skate]

waow technologie

[gilberda]

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!

[GREENPOWERSCIENCE]

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

[neverindoubt]

@gilberda idiot.  LEDs cost about 3 cents each.

[hdcool09]

@neverindoubt U R DUMB

[ObiWanShinobi1]

nice, I've bought a few "40 watt" equivalent LEDs - they're not 40 watt equivalent. Honestly, I think it's limited to sucker green people and stingy misers like myself into needing to upgrade. (the 30000 - much more in some cases- hour life makes it very difficult to sell more of them.)

Intematix website

Solid State Lighting

LED Components page

[erth64net]

I'd rank higher, but there's zero info on the actual model/brand of LED used here...

[Platinumlog]

Where to get these ?

are these for sale somewhere and at what price ?

I´d like to get couple of these for my car :)

like 8 or so..

and 2w efficiency.. why not all the bulbs in my house replaced as well :)

[systemaddictshock]

@Platinumlog

No kidding! Why not replace all the lights with LEDs. Incadescent light is the new "candlelight". It burns hot and has to constantly be replaced.

[Platinumlog]

Leds are quite costy..

at least have been so far.

Maybe its a good idea WHEN i can afford to replace all of em :D

[systemaddictshock]

Yeah, shortly after posting I took a stroll to the hardware store and my jaw dropped when I saw the price of just one LED lightbulb. Guess I better stick to CFL's

[DjBoyo01]

cool, it's still better when you can see it than just keep it to the manufacturer's specifications, it's sure bright for that price, and it's almost power ignorant to other lightes, 6W of pure power brightness

[tronk00]

From Spain. Thanks for all your work, is great. I would appreciated mor info on this item, if you can.

Again, thanks, and Feliz Navidad

[innterru]

посмотрите видео про мощные светодиоды watch?v=UvWerf72OrI

[innterru]

можно создавать наиболее мощные светодиодные лампы, и получать от этого намного больше световой энергии.

к тому же, люди привыкли к жёлтому цвету ламп накаливания

[JeanLouie1106]

...For lighting purposes, I'd prefer a 90w bulb still

[RURC]

Great Dan but NO INFORMATION. If you want to get this type of stuff out there and being used to 'save (LOL) the planet (ROLFLOL)' you should give exact information.

These may be CREE led but I am not sure. GOOGLE for CREE LED and you will hit something. They do make the best and most efficient LED's out.

[20RoyalSuperKing]

so where can i buy these retail in uk

[JaysonX5]

Would love to have these around the house. XD

[killerdoug1]

quite ppowerfull!

[tom500k]

Dan,

Appreciate your efforts, but I need written instructions, a parts list (and source for the parts) + replies to the problems raised (above). Hope you reply with a posting.

best wishes for a green world,

Tom

[insAneTunA]

Great video Dan :-)) I can appreciate the work you put into making and editing your videos.

Greets and a Merry Christmas from the Netherlands, iT

[fergus247]

what a strange effect from 1:14

[ke4uyp]

Here is the company that manufacturers these lights (Intematix Technology Center Corp.) Just google it and you can go straight to their website they are in Japan.

[cambigfoot88]

yay youre finally back with entertaning vids!

[599891]

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.

[marcoze]

where do i get more information on these lights?

[spark300c]

I wounder what will happen if gave ac. It dim and brighten. Or will over heat when the volt reverse to high resistance direction

[SylwerDragon]

It will overheat, only DC voltage is good for them and best thing is led driver with constant current and please DON'T try different voltage or higher voltage , +1 or +2 volts and Led diode will be dead.. I did it with 20W diode. :(

[CmdrTobs]

it would flash, at ~60hz you may not notice it but I am not two sure how well LED pn junctions can take a reverse bias. Probably not worth it. A 4 diode rectifier would give it DC safely and for under a €. A large low volt cap like a couple of cheap 220uFs would smooth it out no trouble.

[nasanction]

What are those LED's from? What sort of lamp is that? Where did you find it?

[aussiezombie]

Can't wait to see you rewire your house dan. Electricity has been announced to go up $200 a year for most families, it's nice to know there is an option. Thank you.

[icovada]

Hey electricity costs up to 600€ a year over here so shut up.

[lezbriddon]

Surely these can be driven from a 12-14v supply without the need to use an old motor as a dynamo! if these are equiv to 90w of light then the HID's i paid $130 for are coming out my car....

[SylwerDragon]

@lezbriddon Not necessary I have led diode (20W) and this one need 16-17V +-0.9V, I = 1050mA but current is important not voltage.

[lezbriddon]

its inportant when you only have 13.7v max lol

although a ebay laptop charger, 12v in 19v out, and then a constant current limiting circuit would suffice for automotive use

[AcidRaZor]

Interesting, this means from my solar panels to my batteries I could run my house lights without the need to convert.... what kind of risk do I take in "zapping" them in that scenario?

[edstar83]

nice thanks for the video.

[kokpigcan]

super LED?

[1RAH]

what was that music it sounds awesome and nice LEDS

[CredoVeritas]

What size heat sink is recommended for an LED of this type?

[penguinistas]

Pardon me for asking but what does one of those LED arrays cost (and where do you get them)? Thankx.

[mathers3000]

search for lumens, dealextreme is a cheap place to buy them. Maybe $5 for one of these. Search around maybe you can find a better place that sells them

[pubtor]

nice

[nephozo]

cool stuff.thanks for sharing

[gsusman]

This is part of why I subscribe. Great vid: informative, creative presentation, thought-provoking, practical.

[27falcor]

where can I get them from?

[CTOL1]

Discrete LED's (1 piece) is what I referenced to, clustered or arrays may or may not have been built as a chip and already have a proprietary control circuit. Getting a hold of the mauf.'s manuals is a good idea.

a single LED is generally not a "lightbulb" and if powered directly from a high current source will greatly shorten it's life or go poof.

These ARE diodes after all, static, or transient voltage/current spikes make quick a death to these. They do turn blueish when over powered.

[galegregory97comcast]

LED IS BAD YOU RETART

[PsychoticusRex]

the other solder points will allow for a "dimmer" like function.

[WeCanAllGetAllong]

Thats a nice set of lights you got there.

[batteryphil]

nice camera work! very creative filming!

[CTOL1]

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

[GREENPOWERSCIENCE]

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

[CTOL1]

@GREENPOWERSCIENCE, check out national (dot) com/ analog/ power.

then Digikey dot com

Most of this stuff is proprietary components, although I think meanwell electronics may make a "box" for turn key operation

Search ----> meanwell led driver ;>)

[CalicoatMaker]

@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

[CTOL1]

@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

[ProfStuartHalliday]

@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.

[centervilletn]

ive been wanting to build an off the grid shipping container cabin and use built in LED lighting run off 12 volt deep cycle batteries charged with an electric fence charger/s.....im very interested in the high output lights in your video...where did you get them?

[wizard4204]

i want a few for poi balls

excellent uses for other things aswell lol

[overunitydotcom]

Very cool LEDs.

I have bought myself already a 3 Watts type and will order a few single High Power LEDs now for

experimenting.

What is the soundtrack music? Great song !

[ricande]

Is it correct to say that those single led's are made up by 4x4 led's ? Looks like that anyway.

Check out pulsefulenerd, he made some tests with these led's.

Once again. Thanx for the vid's. Love the music. :)

[GREENPOWERSCIENCE]

@ricande yes, they are really really small. That square is the size of a screw head. Amazing bright and almost not heat.

[CTOL1]

@ricande , it is likely, as you suggest these are connected in series, or a series parallel configuration. Blue and White LED's are approx 3.5 volt DC devices. Regardless of the connection, they do require a "throttle" or current regulation, unless the unit has that built in. This is still a rapid developing technology. Always check the product sheet and related information

Actually the white light comes from the phosphor over a Ultraviolet blue LED, much like a fluorescent lamp. Cool hey?

[sjh7132]

If you use a parallel configuration, then you need current limiting on each path because slight differences in the LED banks could make most of the current go through one bank.

[anyonefindAMERICA]

Okay there is one answer to the problem. Where do I get them?

[GREENPOWERSCIENCE]

@anyonefindAMERICA This came from IKEA fiber optic set. The can be purchased also separately from the net and ebay check 2w LED 3w LED

[ezone50]

nice were can i get them

[GREENPOWERSCIENCE]

@ezone50 This came from IKEA fiber optic set. GE has some in lights.

[TedFnBuckle]

1st

[TJLewiskoolaidman]

nice

[30GB]

i need one for my rcs
