Replacing fluorescent lamps with LED T8 lights
Our office currently runs standard fluorescent strip lights (1500mm T8 tubes) throughout, with over 60 bulbs across 3 floors. We are considering upgrading all the lights to LED bulbs, in order to save power and to make them compatible with an office automation system (to turn them on and off automatically).
Energy savings
So, how much energy will they save? Well a standard fluorescent bulb consumes about 58w, whereas the new LED bulbs consume around 20W. Therefore over the course of a year I would anticipate the energy savings to be as follows:
| Standard Fluorescent Bulb | LED Bulb | |
|---|---|---|
| Power Consumption | 58 Watts | 20 Watts |
| Hours in use | 10 hours per day, 5 days a week, 52 per year | |
| Hours per year | 2,600 | |
| Kilowatt hours per year (watts / 1000 * hours) | 150.80 kWh | 52 kWh |
| Cost per year (at 10p per kWh) | £15.08 | £5.20 |
Thus the saving is about £10 per year per bulb.
We are currently asking suppliers to quote us for 60 bulbs, and the prices we have received so far range between £25 to £60 per bulb.
The bulbs are rated for about 50,000 hours of constant usage, which should mean they would last nearly 20 years at the rate of usage we have forecast.
Standard bulbs last about 5,000 hours (2 years) and cost around £2 each.
It looks like the energy saving bulbs should pay for themselves after 3 – 5 years, and return a yield of around 20% thereafter.
Things I haven’t factored in:
- Cost of installation / replacing bulbs (slighty more difficult to initially install, but they last 10 times as long and therefore need less labour to replace).
- Reduced heat from operation – might require less air conditioning in summer months)
That’s a 66% saving. Very good indeed. Have you calculated the cost of installation?
I was looking at Megaman LED bulbs the other day. The clever feature is that they don’t require new light fittings. They have a wide range of bulbs but they are very expensive and I would want more than 1 year warranty for such a pricey lightbulb. http://www.megamanuk.com/
Earth LED is another manufacturer to consider: http://www.earthled.com/
The Metaefficient blog has a view interesting reviews of various bulbs and technologies. Here are two:
- http://www.metaefficient.com/leds/led-motion-sensing-lights-a-review.html
- http://www.metaefficient.com/leds/office-building-lit-with-100-led-light.html
In terms of installation, I think it’s pretty simple as they fit in the existing strip light fittings. However, do you do need to remove the starter and ballast, so you might need an electrician to help with this.
I haven’t factored these costs into the equation, but if I did, I think the LED bulbs would probably still come out on top as even though they are a bit trickier to install, you would replace them a lot less often than their fluorescent equivalents… they last around 10 times as long!
Thanks for those other links, I’ll take a look!
I bought LED lights to replace my halogen MR16 bulbs the other day from a website called Eaglelight.com that I would recommend enthusiastically. They had good service (good phone and email support), great FAQs so I knew what I needed, and competitive prices; also, their shipping was fast and the LEDs were as good as advertised. http://www.Eaglelight.com. Very good online shopping site.
The cost of led fluorescent lamps is high, but over time you can dependant on use save 70% in electrical energy and recover your intial cost over 1-2 years.
That is without considering, lamp replacement costs, disposal
HVAC Costs and assist to reduce carbon emissions. You could also see http://www.acousticlighting.co.uk which electronically switch the led fluorescent lamps OFF and ON without damage to the lamps. indcidentally you can have colours of warm white, white, brilliant white. Lamps life 70K Hours with IP65 and IK7 Protection. Hope this helps.
Have you found a source for supplying your requirement? Would you be interested in having all lamps controlled by PIR interface, so the lights are only on when people are in the room, building or designated area..
We have contacted a few suppliers, and are waiting for some samples to arrive – but we haven’t made a final decision yet.
Yes, we are planning on controlling them via an office automation system which will also allow us to trigger them via time profiles, as well as PIR sensors etc..
Is it good or bad to use light motion sensors with t 8 bulbs
LED tube is a new product with much potential and it will must have a very promising market .we also have seen many good markets now .if you are available ,you can visit us at http://del-opto.manufacturer.globalsources.com/si/6008825988218/pdtl/LED-tube/1009101421/LED-Tube.htm or http://del-opto.en.alibaba.com/product/208979393-200036901/High_brightness_SMD_LED_tube_light.html .
we mainly do SMD LED tubes ,not any 5mm LED tubes . in order to dissipate the heat well ,we choose aluminum alloy material .also with acrylic cover is good for lighting transimittance .especially we use PWM driver with constant current to minimize the lighting depreciation and prolong the operateing lifespan . in order to protect leds ,we designed zeners on the back of PCB board ,which is parallel with leds .if one led dead ,the other leds will go on to work .this is a very good feature of our tubes .if you are interested in it ,pls feel free to contact with me : )

99% of LED Fluorescent tube replacements require that the ballast be disabled before you insert the tube, ’ if you are confident do carry out this procedure then by all means purchase one of these tubes.
However if you would prefer to insert a true replacement tube without any additional electrical work then please look at our deluxe tubes which can be placed in an existing fitting without having to carry out any extra electrical work.
Prices for our tubes are shown on line, there is no need to register and there is a handy calculator that you can enter the hours of use to see the savings that you can make.
No company has UL certification for the sale of these products in the USA as of Mid March 2009, our tubes will be certified by the end on March.
We offer a sale or return basis on our tubes, buy a sample, try for 21 days and if you are not satisfied you money will be refunded (you only pay for the postage).
If you want any further information then please contact me on +44 07768 807569 or email sales@ddsultd.com

We help help automate the world…
I am not very good in writing but I found your blog very interesting which I think very beneficial to others in our fields. I wish to read more of your updates on this page…I started my own blog to tell the world what I am really endorsing and selling since I am an account executive of an office and building automation company here in the Philippines…I am trying my best to keep my blog simple and interesting like yours for our customers…Keep up the good work! Tell me how to improve my blogsite here http://unotelelectronics.blogspot.com
in repose to Alistair’s post, people need to be aware of the ballast issue. A standard magnetic fitting with starter is easy to convert and so the LED lamps will work providing the starter is removed. Note however that by leaving the ballast in place, you won’t get as much energy saving due to the inefficiencies of the ballast. It is a simple task to bypass or remove altogether. If you have an electronic ballast which inveriably doesn’t have a starter, the the LED tubes will not work if its left in the circuit so these will definitely need to be bypassed. If you are planning on using a passive movement sensor then be aware that some may not work properly as most reply on a resisting load with solid state output . The input impedance of an LED tube is pretty high and you may find that if you are powering just a single tube, that it may not work unless you put 2 in.
If you have any questions about LED tubes, lets share it so we can all help each other.
Dip led tube and SMD tubes are the major products in the market.

Actually,electric ballast will consume energy, remove ballast is more energy-saving. I know many company of UK have been in led lighting for many years,bus seems less people buy large quantity for led tube. I don’t know what the reason is. We have dealer in Australia right now. We hope to find a good parter for our led tubes in UK. Our advantage is as follows,
1. High power factor: 0.95.
2. No flick,No LEDs dead.One led dead,other leds go on to work.
3.AC90-265V,AC90-277V,DC12-36V voltage for different environment.
4. CE,Rohs, Australian,MET(US market)certification.
We have series led tube to meet different requirement, 2feet to 8feet are our general items If you are interested in our tubes,pls feel free to contact me.

Great! It is always refreshing to hear that someone is moving forward in not only saving money but also reducing their CO2 emissions. As with Pete Bailey’s company Visual Interactive Ltd we too advise on Carbon Trust loans – for this year I believe £100M is available!
LED technology is the way forward and we love to share information so that individuals and organisations can then make an infomed decision as to whether or not to purchase LED lighting. We have seen clients achieve a pay back of less than 12 months on their investment.
No longer are LED lights ‘those multidiode blue lights’, you can now purchase warm white to daylight, or if you want blue, red yellow etc you can have these too. I look forward to Paul enjoying the savings that our clients have enjoyed.

HI, If you are looking to buy from a UK company and you want a no hassle upgrade from standard fluorescent to LED T8 lights then we have the answer…
Many people find it tricky and more costly when having to modify the power supply ,in order for the LED T8s to work ,and LEDS work best with their own LED power supply , therefore we don’t use ballast to power up our LED T8′S , as that could lead to damage and higher running cost..
