'Most energy-efficient' light bulb

Good morning fellow ATSers!!

I did a search and didnt find anything and thought it was worth sharing.

This project, from University of Toronto Grads, went way above expectations

The project had originally hoped to raise $20,000.

The Nanolight, billed as "the world's most energy-efficient light bulb" has raised $133,022 on the U.S. crowdfunding site Kickstarter and generated pre-orders for more than 3,000 bulbs since the project started seeking backers on Jan. 7.

Their design consists of a circuit-board with LEDs attached to it, folded up into the shape of a light bulb that plugs into a regular lighting fixture.

I find this quite interesting as regular light bulb burn out pretty fast and this is the first time that LED are considered for lighting (other that flashlights and the sort). LED life span is very long so this could become very popular and fast. I cant wait to see what else will be developped since they are currently working on other models.

The Nanolight team is currently working on other light bulb models, including one that is dimmable.

What does ATSers think of this?

I thought that fluorescent was still the most 'energy' efficent. But not by much.
The big cost savings was in the lifespan of LEDs.

Maybe it's changed since I last looked.

Looks great.

Wonder if it will have a glass lens around it though...the light from those LEDS might be too harsh if it's not diffused a little.

What's the wattage of this thing? I'm guessing they are 1W LEDS, so perhaps 25W total?

ETA: Never mind, just read the article...it's 8W - 12W. Impressive.

Thanks for posting.

I'd say this was more energy and cost efficient.....



CX.

There has been LED lights out for a while now. Just about any home supply store like the home depot has just about any kind you want.

LED Light Fixtures

sorry but led light bulbs have been around for years. here in europe there easily gotten for all different fittings. they even have dimable ones now that work pretty well. they had to make a special transformer and a special electronic dimmer but have gotten all the bugs out and cost has dropped dramatically. the first ones i put in our house was 6 years ago in the bathroom and i still havent changed them. i did however have to change 4 in 1 room in the space of about a month, but that was down to a bad batch i believe.they are the future tho.

LED bulbs have been out for a few years:

www.ledbulbs.co.uk...

LED's have been available for a few years. They are substantially more energy efficient then incandescent, and consume about 1/3 the energy of CFL's. They are a bit more pricy, their light is more directed then diffused, but give them a few more years and they will be the go to lighting source.

Local company LED of North America designs LED's, and they were on the news last night showing off their stadium lights that are more energy efficient then the ones in the superdome, and would restart instantly as opposed to the mercury filled ones they used.

I like the design of the multifaceted surface, a unique geometry to provide a dispersed light. I don't think it is the most efficient bulb though, at 133-150 lumens per watt. The cree u2 leds get 160 lumens per watt @ 350mA. I also have some nichia's that do 170 l/w.

but does it put out a lot of light.

Thanks for bringing it up Buster (and others), the way the article put it, I really thought that this was a new thing as I have never heard of these before (as a bulb), but I stand corrected guys!!! this is NOT new, just a new style of them.

I had only seen LED lights in flashlights, night lights,etc...never bulbs....but EH!! We learn something new everyday right.

I feel like I have been under a rock for a few years...

Thanks all.

Yeah they have been around for quite some time, my father in law uses them alot. I've built a couple of LED grow light's for a couple of customer's diy kit's are pretty cheap. Some will agree some won't because they havn't been around too long! Old school people like their HPS but when i compare the growth and strength of the plant's I usually get them to sway toward's the led. They do let heat off that's a myth and a heat sink is needed but nothing compared to HPS or HID! I havn't done the reasearch, but if remember off hand I think 60watt led is compared to a 400 watt HPS. The only thing is that you have to use a royal blue and a deep red 440nm/660nm and with the color's it's hard too keep in the house unless you want everyone to think you have rave going on....

Hmmm my house is about 60% LED lights. 20% florescent and about 20% old school bulbs(which are mainly in bathrooms and basement).

LED is better long term investment because it lasts longer but currently their is cost is higher - when they mass produce, LED will be the best.

Florescent - at the current moment has the best cost/efficiency ratio - but vanity wise, LED takes the cake.

Oh yeah ...

You know what is going to be fun to watch? Which company screams patent infringement first.

I got my whole house fitted with these,

m.philips.co.uk...=LED_BULB_SU_GB_CONSUMER%3Dtrue;compareState0=id0%3D%2Cid1%3D%2Cid2%3D%2Ccomp areView%3Dfalse;productState0=page%3D1%2Csort%3Dsubcat_asc_group

saves hundreds each year... the catch, there expensive but last a lot longer then regular bulbs.

One thing rarely taken into consideration when spouting figures on efficiency is the energy (both electrical and man-hours) used in the manufacturing process. Not only in the manufacturing of the item itself, but the energy cost of manufacturing individual components used. While it might be good for the end user, the one who pays the electricity bill, it's misleading.

depends if your trying to save the world or cut costs for your electricity bill.

i thought the colour spectrem of led light was wrong for growing plants, compared to metal halide and mercury lights? could make a cheap indoor all year green house tho if its true

This is nice, the bulb looks almost like a toy, lol. I wonder how a lamp shade would work on those due to their shape? Probably would require an adaptor or something, unless there is another model that they will work onto.

There's alot of controversy over it, and finding that right spectrum for the specific plants i think is the key. Different plant's need different light im pretty sure but don't quote me on that. I've noticed since they discovered led's can grow plant's, several companies claim different light spectrum's saying it's better than other's. Some add orange and yellow's while some say just red's and blue's....I use them with just the red's and blue's with a 3:1 ratio since blue is brighter. At the end it come's out as a purple light which will cover all growth cycle's, from seedling, vegitation and flowering. works awesome with tomatoes!

Some die hard's will use the specific spectrum for the specific cycle's I havn't done it myself but they claim you get more growth doing it that way, it's still fairly new to me and still working on finding right spectrum.

And yes is very cheap lighting for all season imo...just hard if you have different plant's with the daylight and nighttime, or manipulating them to think the season is almost over to start flowering but you can manipulate any plant for that as long as they are mature enough...

Alot of illegal growers switch to them cause they are less detecable, with less heat! That's actually were i researched led's from was at those forums, made me very nervious just being there but those guys really know's what their doing!
