At the moment there are few reasonably priced LED bulbs available. I'm currently testing some 7 watt warm white bulbs, they were quite pricey at about a tenner each but in theory should last much longer than CFL and a great deal longer than incandescent bulbs.
So far the LED perform well with immediate brightness and no warm up or delay like CFL's.
Brightness and light qualities equivalent to a 60-70 watt incandescent bulbs.

So how may an average teacher make this into a bulb, using as you state a jar. It needs to be stable and usable. (I have not read all of the comments, just in case there are detailed directions shared). Thanks!!
Xmas lights are great for lighting. We have a pantry in our house that was really hard to see in. I added a plug in the ceiling that is wired into the hall light only 2 feet away and strung a length of the small LED lights around the inside of the pantry. My wife LOVES it because she can see everything on every shelf. I'm going to do the same thing with lights out on my porch. Great lighting and energy efficient!
Dan- check out dealextreme- they have 100 watt (straight not equivalent) LED modules for $65 and free shipping. Slightly better than a buck a watt... :P
This isn't actually as good of a value for money as you think it is Dan. Not only do these multi-LED lamps last less (they dim much quicker due to really poor heat dissipation and driver design), but you can also just put 2 x 20 cent 1 watt LEDs together, and you'll get a much better result (provided that there is an appropriate heat sink), especially since most of the LEDs used in such car lamps are of very low efficiency (most likely 40 lumen/watt - and I bet they don't go past 75 lumen/watt).
ok, so here is a crazy idea, what if you get a really intense LED bulb that can activate a solar panel to charge the battery it is powered by and sustain it's own energy requirements?
Those bases are G4 from doing variant searches. I think they are optimized for use in car lights. They have E27 screw-ins too. Lots of other base types too.
True, but useless if LEDs are connected in parallel. LEDs like any diodes fail if connected in parallel without voltage equalizing resistor for every single LED or gorup of LEDs connected in series.
Being the genius I am, I worked out that IF you string enough LED's together, you can bypass the need to use current limiting, due to thermal run away.
e.g. Assuming 3V 20ma LEDs - OK on 12V - your theoretical peak brightness would make them run at 4 LED's in a string with a current limiter.
Due to their own internal resistance, if you run a string of 5 or 6 of them = natural current limiting - you have near full brightness, and a very long life for an LED, with no complex circuitry or loss's.
Thanks! I started to realize the need to have a controller or voltage limiter when I just tried to convert standard tail lights to LED tail-lights on my little bus : ).
I like how the video alerted us to a product I wasn't aware of. But respectfully a video really can't convey how well a "bub" does. Even lumens per watt can't really convey that. Personally I believe household lighting in general & LED lighting in particular will be evolving for decades. And at that it will require people to adjust how lighting will change from incandescent
Those would make great brake lights under the red filter.12 volt and bright.I have seen cars all over with lights out either a headlamp or a tail but many car on the road are not up to specks.
For 1W will not be bad but for 2W is not great I have some strips with the same LED's and are not that great I will not recommend them.
Is hard to get an idea since the eyes auto adjust to light and camera has usually auto brightness.
I made a good test that also includes this led's with the camera set on manual so you so you can much better compare the different light sources. I also have a luxmeter but is not as useful as a camera set on full manual.
I've been buying LED bulbs recently for indoor use. I have found some 4 watt frosted LED bulbs with a cooler color temperature that nicely illuminate my desk and work areas, and don't get hot like CFLs or incandescent. I find the cool white color very relaxing and pleasing, sort of like listening to good music. I also use LED night lights to give dim light around the house at night. I imagine the total use of electricity for night lights isn't more than 4 or 5 watts.
People dont realize LEDs are the future of lighting. This push for CFLs is confusing, while LED bulbs are on the horizon and are far more durable and much more energy efficient. I bought one led bulb a few years ago(on ebay) and it has yet to burn out, while the CFL bulbs I buy all seem to burn out well before their claimed lifespan. They have started selling LED bulbs in hardware stores, so not much need to rig your own unless you're using a special power source :)
@BrownEyesack I have read that the promotion of CFL bulbs is a political issue: some places will give you tax credits, etc., for buying CFL bulbs but there is nothing yet for LED bulbs.
@bodryn The only thing that was ever promoted was more energy efficient light "bulbs". At the start CL where the only affordable option that meet new standards. LED aren't even close to being affordable yet. They are getting more affordable at a time when there are also incandescent that meet the energy efficient standards. The only obvious political issue that I saw where some making political hay by misrepresenting the facts & still R doing do
@waswestkan I think I have a dozen or more LED bulbs, all affordable. Maybe you're referring to BIG ones. Mine range between 1 and 6.7 watts. 2 watts gives you a nice area light over a desk or chair but for reading I prefer 4 watts. With a swing arm lamp I can get a comfortable reading level with a 2 watt bulb. These are both affordable and convenient because they don't throw out much if any heat.
@bodryn Yes I had the bulbs used for general room lighting,caz those a R the 1s that the Eff. strds. R targeting 1st. & the bulbs most will be seeking to replace Getting more affordable isn't relative, when most are interested in the cost when when they are forced to replace bulbs For many spot lighting isn't comfortable & will resist that route as long as they can. I'm not anti-LED & I have been experiment with the affordable LED bulbs, but they aren't working that well for me available
@BrownEyesack Can you really just pick up LED bulbs like a normal bulb now, no need for a special circuit. How much would that cost, I also think LED is the future but I heard its still too expensive for housing
@ricochetVendetta I currently have 2 LED bulbs in my room. They are 2 watts each. They have a standard screw base. So they work with any standard light. If I remember right I payed $16 each for them. I picked them up in the bulb section of my local mega mart. Right by the florescent bulbs.
@ricochetVendetta yes. they are little pricey right now (especially the high end ones) but see that price dropping as they continue to engineer them to be easily manufactured. If you think about it tho, led Christmas lights plug right into the socket so to me its not much of a stretch to condense it down into bulb form
@BrownEyesack The only thing that was ever promoted was more energy efficient light "bulbs". At the start CL where the only affordable option that meet new standards. LED aren't even close to being affordable yet. They are getting more affordable at a time when there are also incandescent meet the energy efficient standards. Incandescent (those that meet current standards) will have a comeback until newer stricter standards favor LED.
@ricochetVendetta It depends where you live how long is the night and how long is the day also if it will be or not a sunny day and if not if you want the battery to work for two or 3 night without sun during the day.
Eg. 5h of full sun and 10h night you need 2W LED for 10h is 20Wh for one night so the battery need to be able to provide that Lithium battery can discharge 80% so you need a 25Wh battery and and about 4 or 5W solar panel.
Dan could you show a watts meter LEDs and CFL bulbs on the ac ones . most of my CFL bulbs are 40 watts and higher (to 90 watts) when rated at 14 watts (all of them) . Just want to know if you see the same thing . i was using them off a solar battery inverter system , now i only use LEDs . the rating is off or is it just me ? Killed my batteries way to fast not to be right. mine are the GE CFLs but all are not rated right or is it the watts tester i'm using, plug in type?
tip when buying LED products, look at the color temp. the closest to a warm white such as a normal incandescent filament lamp is below 3000K (Kelvin) Cooler lights are of higher temp and look more green or bluish
The ones you are showing look to be about 6000k-6500k
Usually the phosphor on the LED if warmer is more yellow when off
Cool. After your last vid about newer large led bulbs I went out and bought one. $20 for their newest 60w at only 18w usage. Works great so far. Plenty of light and will work great with my solar battery back up for sure. Thanks.
@v3511 Color temperature is actually a common measurement used to describe the wavelength, i.e., the inverse of frequency, which is what determines color. The red end of the spectrum has longer wavelengths, maybe 3200K (Kelvin) whereas the blue end may be over 6500K. The sun is considered white, so for a natural daylight look, you'd want a color temperature probably over 5000K. Also, if you google spectroscopy, you'll find the astronomical approach to color temperature.
@30GB Efficient compared to what? Lumens per watt is the only valid comparison. Doesn't matter how many die in each LED or how many LED are in the bulb. Not to mention the area actually illuminated. As things stand now a multiple LED "bulb" is likely to illuminate a greater area than a single LED

not so bright.... better off with a bigger single led because each led has like 3 inside so they are not so efficient

@30GB Efficient compared to what? Lumens per watt is the only valid comparison. Doesn't matter how many die in each LED or how many LED are in the bulb. Not to mention the area actually illuminated. As things stand now a multiple LED "bulb" is likely to illuminate a greater area than a single LED
