Is Cold Cathode energy efficient?
Yes, standard output will consume 30w per mtr and give around 1800 lumens per mtr. Lesser wattages per mtr are achievable, down to app 12w but the light output is reduced to app 700 lumens per mtr. High output systems will consume 60w per mtr and give app 2800 Lumens per mtr.
How long will it last?
We state 50,000hrs but with advancements in cleaner Phosphors, our state of the art Oven Pumping method and our rigourous quality control, it is not inconceivable that 75-100,000hrs would be possible. Cold Cathode is a proven technology that has been in existence for over 50 yrs, and there are many examples where lamps have achieved such longevity.
Can it be dimmed?
Yes, we can dim by Phase Trailing or Leading Edge, 0-10v, DMX and DALI. Lamps will typically dim down to 10% of Lumen output.
What colours are available?
We can supply just about any temperature, beginning with 1800k, 2400k, 2800k, 3000k, 4000k, 5000k, 6500k and 8000k. We also have a range of colours such as Red, Blue, Green, Bright Yellow, Golden Yellow, Orange, Pink, Purple, Violet and Lavender etc.
Do you install?
We have our own engineers whom travel throughout the UK, Europe and the Middle East, whom are fully qualified and experienced in the installation of all types of Cold Cathode systems. If you require full installation by our engineers, or just on-site training, the choice is yours. We will always advise that we install our systems, to maintain the standards we and our clients expect from a Kemps system.
If you are exporting to another country, will the lamps get broken in transit?
We export hundreds of lamps every week by air and sea across the globe, and with our tried and tested packing methods, the actual breakage rate is less than 1%. Spares are always included, so this is never an issue.
What happens if a lamp fails in the future?
All or lamps are tagged with its own unique reference number, so all you have to do is convey this to our sales team. Our records will show the exact details of the lamp you require and this can then be passed to our Production Dept for mfr and dispatch.
What’s the longest and shortest lamp possible?
All lour lamps are mainly made from 20mm diameter, and are powered via low voltage(<990v) Convertors, so we are restricted to a maximum 1950mm in length, with the safest shortest lamps being app 400-500mm. We can mfr any length in between these figures.
Why do you use 20mm diameter?
This diameter gives us a max length of 1950mm, but more importantly it provides a high Lumen output which the Lighting Designer needs. This diameter also runs cooler than smaller diameter lamps, which assists in maximum lamp life. Smaller diameters such as 18mm or 15mm require more voltage, hence the max length reduces which increases the total cost. We do have 25mm and the maximum lamp length is app 2400mm, though Lumen output is 30-40% less than 20mm.
Where are the Electronic Convertors or the Magnetic Transformers that power the lamps located?
Electronic Convertors tend to sit mainly in the ceiling cove, underneath the controlling two lamps. These are lightweight, app 500g, and are app 300mm L x 60mm W x 45mm H, so most architectural details are large enough to accommodate the lamps and the Electronic Convertors.
We do use Magnetic Transformers for mainly building façade lighting, as these can be located upto 60mtrs from the two controlling lamps. These are only available as mains dimmable Transformers. The weight of each one is app 7kg, and the dimensions are app 300mm L x 60mm H x 70mm W.
