April/August 2017 – West Park & Friesland Sports Centres move to LED to improve lighting and reduce costs

LER recently completed the retrofit of 400w Sodium lamps to 100w low-energy LED Sports Lighting at West Park Sports Hall in Long Eaton (www.erewash.gov.uk)

The customer commissioned LER to design and install the new low-energy lighting in order to improve light levels and reduce energy bills by over 50%.

LER removed the old, yellowing sodium lamps and fitted new modern design LED floods at a height of 8m.

 

 

 

 

 

 

 

 

 

 

 

 

Lumens levels have been dramatically increased as can be seen on the adjacent picture, and anticipated annual electricity savings are expected to be in excess of £1500.

 

Coupled with the introduction of PIR’s sensors in goods in and despatch, the customer expects the project to pay for itself within 3 years – and the midi-bay lamps are guaranteed for 30,000 hours!

 

We had a slight issues with the PIR’s operating intermittently due to the close proximity of ceiling-mounted gas heaters. LER asked the local lighting manufacturer to accompany us to visit the customer to adjust the PIR sensitivity to compensate for this – whilst recognising when a member of staff came within 5 metres of any of the lights fitted with PIR. The lights are programmed to be turned off after 5 minutes without detecting activity, producing further energy savings.

 

The customer, who predominantly prints on metal foil for the pharmaceutical industry, is naturally delighted with the new lighting system and has now asked LER to fit a number of low-energy LED floodlights around the exterior of the factory in place of power-hungry unreliable halogens!

Which Way To Go – Fluorescent or LED?

WHICH magazine has recently highlighted the benefits of switching to LED lights and their ‘best buys’ for replacement bulbs

The drawbacks of Fluorescent Lighting…

1. Failure From Frequent Switching– Fluorescent lights tend to burn out faster when integrated with occupancy sensors and other controls. In contrast, LEDs work perfectly with control systems, since their life is not affected by turning them on/off.
2. They Contain Mercury– LED lighting is Mercury Free; making them safer for the environment with no disposal or recycling fees.
3. The ‘Buzz’ with Ballast– LED operate silently.
4. Unstable Lighting Quality– LEDs produce light in a variety of colour temperatures similar to fluorescent, but don’t have any flickering issues.
5. Not As Efficient– The latest T8 LEDs are around 30% more efficient than T8 CFLs.
6. Most Fluorescents Cannot Be Dimmed– LEDs have full dimming capabilities; fluorescents are expensive to dim and do so poorly.
7. Light from a Fluorescent Bulb Is Non-Directional– LEDs offer directional light (illumination exactly where you need it); fluorescents have multi-directional light, which means some light is lost in the fixture and other unnecessary places.
8 Lifespan- Compared to only 30,000 hours for fluorescent, the average lifespan of a T8 LED is 50,000 hours

May 2016 – The Answer to an 8’ Problem

The main problem with 8’ fluorescent tubes is that they use an enormous 100w of power per tube (add 10% for the ballast). Because of their superior light output they are often mounted in higher locations in warehouses and production workshops; this makes replacing them (they are not known for their longevity) awkward, time-consuming and expensive.

8' Fluorescent tube

Unfortunately 8’ CFL tubes are becoming increasingly hard to source and increasingly expensive to buy.

 

We recently supplied a Long Eaton warehouse with a quantity of refurbished 8’ luminaires pre-fitted with low-energy 42w LED tubes. The LED tubes are guaranteed for 5 years, and with the lower power requirement (but improved lighting levels) they will save the client a whopping £2800 per year in electricity. Plus a lot less hassle changing and replacing each time a CFL goes down!

April 2016 – Derby precision printers see the light and move to LED!

No Comments

LER recently completed the retrofit of 30 x 400w Sodium lamps to 30 x 135w LED midi-bay luminaires in a precision printers on Ascot Drive, Derby.

 

The customer commissioned LER to design and install the new low-energy lighting across 4 departments including goods in, slitting, printing and despatch.

 

LER removed the old, yellowing sodium lamps and fitted new modern design flat midi panels at a height of 5m.
