Re: The LED Evolution: Revolutionizing Lighting by Noble11(m): 8:38am On Jul 31, 2016 |
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 1 Like

talk2riel: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 7 Likes 1 Share |

Noble11:The Nigerian market is flooded with them already.problem is, its mostly trashy quality.please one pic would have served just well. I'm trying to keep the posts here to the barest minimum and the pages as light as possible for easy reading. Hope you understand |
Re: The LED Evolution: Revolutionizing Lighting by talk2riel: 9:02am On Jul 31, 2016 |
allCopacetic: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. |

topsy23: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. |

Re: The LED Evolution: Revolutionizing Lighting by allCopacetic: 9:12am On Jul 31, 2016 |
talk2riel: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 |
Re: The LED Evolution: Revolutionizing Lighting by allCopacetic: 9:17am On Jul 31, 2016 |
3.Manufac. specifications Sadly not many bother to read product specifications. most times the information you need to guide your choice is right in front of you. from the listed specs on the drivers below you’ll notice the branded drivers can both output 300mA, while the generic outputs just 110mA that’s only about one third the output current produced by the other two.

4. Distinctive/innovative features - New or distinctive features will constantly be added to good products to improve functionalilty. If you look at the clips on the sides of the two branded panel lights below you’ll notice the extra plastic added to make clip sturdier and the grip firmer. Manufacturers of generic brands wont bother with extra features like that because they’re gunning for low costs

Because LED lamps are generally very durable, (by virtue of the technology employed) and because electricity is barely existent here…. You can buy these cheap generic variants and they might serve you well for over six , twelve or more months. But If you get twelve months from a generic, be assured you’ll get considerably longer service from a higher quality branded . In addition , you’ll enjoy higher light output per watt (luminous efficacy) with the higher quality branded types .i.e you get brighter, more efficient lighting. |
Re: The LED Evolution: Revolutionizing Lighting by ceaser: 9:32am On Jul 31, 2016 |
allCopacetic: 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. |

Re: The LED Evolution: Revolutionizing Lighting by ceaser: 9:44am On Jul 31, 2016 |
ITbomb: 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. |

omonighoblessing: What are you studying? |
Re: The LED Evolution: Revolutionizing Lighting by allCopacetic: 9:49am On Jul 31, 2016 |
ceaser: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 |
Re: The LED Evolution: Revolutionizing Lighting by ceaser: 9:58am On Jul 31, 2016 |
talk2riel: 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 ). |

Muyiii: You're working with Fibre optics with that? |
Re: The LED Evolution: Revolutionizing Lighting by ceaser: 10:16am On Jul 31, 2016 |
allCopacetic: 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. |
Re: The LED Evolution: Revolutionizing Lighting by midastouch: 11:05am On Jul 31, 2016 |
allCopacetic: 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....' |
Re: The LED Evolution: Revolutionizing Lighting by Saipro(m): 12:03pm On Jul 31, 2016 |
midastouch: 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. *runs away for fear of being insulted* |

Re: The LED Evolution: Revolutionizing Lighting by JSoE(f): 12:29pm On Jul 31, 2016 |
midastouch: 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. |
Re: The LED Evolution: Revolutionizing Lighting by ceaser: 12:32pm On Jul 31, 2016 |
midastouch: 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. |
Re: The LED Evolution: Revolutionizing Lighting by Standing5(m): 1:24pm On Jul 31, 2016 |
ITbomb: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. |

Re: The LED Evolution: Revolutionizing Lighting by Janyves(m): 2:53pm On Jul 31, 2016 |
CFL..... Led.... And their drivers are all not friendly with power surges. One needs a stable voltage source to enjoy their energy saving functions. ............. |
