Good topic...
This is my own contribution especially for the small scale importers..
There is a new LED BULB that's rechargeable,it can last up to 5 hours when light goes off and its automatic..I don't know if it's in Nigeria yet..
I made a good fortune importing from China to Kenya also the first person to do it there,but it has flooded the market now..so I think it can sell in Nigeria,as you know we don't have enough electricity..comes from 5 watts to 12 watts..also can be used as candle or touch
You can get them from Alibaba if you don't have an agent already.

PERMISSION FROM THE OP PLEASE

but they are expensive and fragile. 6*6 feet cost well above 18000 , a little trip from the choke and the fitting is gone

That would depend on your understanding of Expensive,
We need to be more calculative in our cost/benefit analysis

LED bulbs are cheaper to use than CFLs (spiral bulbs) not just in terms of energy costs but in replacement costs aswell. The savings you make from the use of LED lamps can offset your initial investment within months.

consider this

a phillips 20w spiral bulb for instance cost about 650-700, while a phillips 6W led bulb (which arguably produces more illumination) cost about N1000

the current elcectricity tarrif for R2 Residential consumers (single phase) served by IKeja disco is approx N21

at 6 hours runtime per day, a 6w led will consume -(6x6x365)wh =13.14kWh in a year
working for the same length of time, a 20w cFL will consume- (20x6x365)=43.80kWh in a year

with the current tarrif regime it'll cost N(21x13.4)= N281 to run a 6W led bulb,for 6 hrs a day, for one year
while it cost N(21x43. =N919.8 to run a 20W CFL bulb for the same period

which means for a household with just 10 bulbs you save N(9,198 -2810)= N6,388 every year for your choice of LED over CFL, and N24,784 for LED over a 60W incandecent bulb (using the same analysis as above)

in terms of replacement cost, LED bulbs are known to last 2 to 5 times longer than CFLs and 35 to 50 times longer than incandecent bulbs.
which means that in 2 to 5 years you would have spent more money buying CFLs than you would on LEDs .

The single most important thing is buying a good quality. And note the cost analysis above is for Phillips, which is one of the most expensive brand. there are less expensive alternatives that give good value too.

And about being fragile.. as said earlier, they are more durable than most other lamp forms, you just need to spend money on a good quality. these things are used all over the world, and are phasing out other lighting types. Nigeria is no different.
besides... 6ft x 6ft LED do you know what dimension you're talking about

sorry I meant 2 x 2ft


As good as this economic Angle sound the risk of installing LED is just to high. I personally had to replace 5 unit on a site. A little fluctuation in current Burns them up.

Good idea brother.....my concern these days is the chaina made LED light that are flooded in nigeria market. There is a panel LED light I bought from Locks&Switches at Lagos island, one LED of 220mm diameter is N12,800

Thats the thing, people continue to waste thier hard earned money on fake items in pursuit of cheap prices. Buy good products and enjoy value.
There's nothing wrong with being made in china, some of the best qualities in the world are manufactured in China. The problem is the lack of enlightenment that is increasing the demand for fake things in Nigeria, and this is driving the supply, creating a flood of cheap substandard products.

That would depend on the quality/brand you buy, I'm sure it probably has a generic driver. people have used these things for years. besides you can replace just the driver in the event that it burns out

Awesome post...I'm currently doing my PhD research on LED for data transmission (Li-Fi). Light fidelity...I'm glad such posts are springing up here. Thumbs up!

allCopacetic:
Generic products are generally cheap, mass produced options. They can be said to be made to no particular standard or quality index. They carry no branding or distinguishing feature . So anybody can print a pack with a brand name and package these generic lamps in it. One of the most important parts of an LED lamp is the LED driver. This converts AC to DC which the LEDs require to work. So when you buy any LED lamp look out for the quality of that driver.

So What do you look out for in an LED driver ? and how do the branded differ or distinguish themselves from the generic.

Very correct that generic products flood Nigerian markets. The good brands like Philip et al are more expensive. Some generics however equally works as good and last as good as the popular brands.

Also some LED drivers, usually having G4 connectors, are designed to adapt to either VAC or VDC (AC or DC voltage) input so long as the voltage source do not exceed the stipulated, usually 12/24 volts. The G4 drivers are also spared of polarity restrictions (no +ve or -ve to worry about as it works equally well both ways)

I recently finished constructing about 3 units of G4 LED drivers to replace some CFL security lights.

Hmmm

Technological innovations were supposed to make things better, faster and cheaper.

In Nigeria, new products with almost the same capabilites as the previous products tends to be more expensive

It's normal for new techs to be initially expensive. The producers need to make returns from their years of researching the successful product. Also there is the issue of patent for some years. Once patent runs out and mass production by all players begin, prices crash.

Nigeria's case is always absurd though and defies logic.

Good job op. this is more or less my seminar in my final year.
OLED ;organic light emitting diode.
more like the advance of LED.
OLED IS THE PRESENT OF LED NOW.....

What are you studying?

A lot of good brands are more inexpensive than phillips,

a generic cannot work as good or last as long as a higher quality branded if they work under the same conditions, in as much as the components differ in quality and specification.

Besides, if they're generic (unbranded) how do you identify the type that "might" last long. thats the essence branding, giving an identity to a specific quality.

regular LED drivers like all the above attached are not polarity sensitive either

Except those ones have the drivers integrated and sealed into the units, you may have needed to replace only the drivers without the hassle of replacing whole units. It's the cheap components in the drivers that usually burn out first, especially capacitors and resistors. Typically, the LED chips 'emselves outlast the drivers. In fact, you can even replace the LED chips with some knowledge in electronics (not electrical o ).

Sorry, i just got the generic you mean now. I meant to say unpopular brands like the Philips.

220 VAC is not polarity restricted. But at the output terminals of some of the drivers above, the Vout usually ranges from 11.5VDC to 18 VDC and is polarity specific.

I was actually talking at the level of lower voltages of 12/24 VDC direct as the mains voltage. That's what powers all the lighting points in my crib. I avoid experimenting with 220 VAC na Na you be don for that department.

Working with LEDs can be pretty exciting. LEDs is taking over lighting like Lithium chemistries are taking over battery majorly from Lead acid and less majorly from nickel cadmium et al.

There's a revolution in the lighting market, and the catalyst is the light-emitting diode technology, better known as LED

An lamp is a light-emitting diode product which is assembled into a lamp (or light bulb) for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent lamps, and significantly more efficient than most fluorescent lamps, with some chips able to emit more than 300 lumens per watt (as claimed by some LED manufacturers). The LED lamp market is projected to grow by more than twelve-fold over the next decade

LED LIGHTING IS CURRENTLY WITHOUT QUESTION, THE SMART WAY TO GO

Over the years, lighting technology has evolved from the use of incandescent bulbs, to CFLs (spiral bulbs) and now LEDs. A significant difference from other light sources is that the light is more directional, i.e., emitted as a narrower beam. LED lamps are used for both general and special-purpose lighting. White-light LED lamps have longer life expectancy and higher efficiency (more light for the same electricity) than most other lighting when used at the proper temperature

Simple rules of grammar. You qualify a noun with "an", if only it starts with a vowel. If not you use "a".

Your sentence should start with 'A LED lamp..... ' not 'An LED lamp....'

Actually, it's the starting sound (remember phonemes?) which determines the use of "a" "an" as a precursor. Pronounced "el-ee-dee" rather than "led", the OP is right. "An lamp" is wrong but "An LED lamp" is correct. Cheers.

Depends on how you call it. If you pronounce it as 'led' then you use 'a' but if you spell it out as LED -/El i: di:/ that's when you can use 'an'.So logically,you two are correct.

Bro. You are the wrong person. As one above pointed out, it's pronounced "el-ee-dee". I too had a hard time getting used to that cos even till date, I occasionally call it as it is: LED instead of calling out the acronym.

It is not all technological innovations that come cheaper at the onset. Electric cars and LED bulbs are example of such. One factor that makes Nigerias own even more expensive is the fake products factor.

Chief, bastardizing Ossymac products isn't a wise idea. You can use pictures alone without the label or mention product name without the pictures.

Dude, please send me your contact and direct on how to buy

Thank you!

CFL..... Led.... And their drivers are all not friendly with power surges. One needs a stable voltage source to enjoy their energy saving functions. .............
