Frequently asked questions

A seven-year battery life impressive for a lead acid cell.  How do you guarantee it for so long?

Because of the way our system uses the batteries and controls how they are ‘cycled’ we are able to guarantee their life expectancy for 7-years.  We ask you to accept the FSA backed warranty that the system will do what we claim.  Any risk is therefore not with you as the client, and no insurance company would insure this risk had they not carried out a very thorough due diligence on our products.

Is there any data to back up your claim that Commulite’s payback period is under three years?

Three years is  typical, and we would be pleased to run you through some real life examples.  Of course, every installation is unique, and the payback time depends upon switching times, usage etc, but we will give you an accurate payback time before asking for any commitment from you.

Why is the Commulite system so superior?  Surely all LED lights are ‘maintenance free’?

Commulite has a unique design that places no fallible components within the lamp enclosure, meaning we can fit enclosure with a tamper proof seal for life.  Other manufacturers’ fittings may contain drivers, battery packs, inverters etc, which all require periodic maintenance. Furthermore, these other components generate heat, which affects LED performance and longevity.  Commulite fittings are tested and guaranteed from -40∘C to +50∘C, and are much better design for “real world” usage.

How can Commulite achieve such good light levels whilst using so little energy?

Many LED manufacturers find they lose up to 40% of the lamp’s light to the diffuser. Our unique “LED 28” OPAL diffuser loses almost no light output and ensures an even dispersal of light without glare or spotting.

How do you support the claim that your lighting system is more energy efficient than other LED systems?

Commulite fittings each feature four independently-controlled circuits, which means we they can be set to offer nine different light outputs.  This means we can tailor every fitting to suit its installed location, time of day, and time of year, thus ensuring optimum use of energy.  Other LED light systems are either ON or OFF at 16w.

How robust are the Commulite luminaires?

Extremely robust and resistant to wilfull attack, because each fitting incorporates four circuits, with a virtually indestructible board of over 60 LEDs, it is almost impossible to completely disable that fitting.  The fitting can even be attacked with a hammer and still have LEDs working.

You claim a 65% energy saving compared to traditional fluorescent lighting.  Where do you get this figure from?

Our calculations are all based on real schemes.  While we advertise savings of 65%, we are often able to achieve 75% thanks to our unique intelligent control system.  We will undertake accurate surveys and provide energy forecast for every installation before asking for any commitment, completely FREE OF CHARGE.

The Commulite emergency lighting system is fed by a centralised battery rather than individual battery packs. Does this mean that the supply cables need to be fire rated?

Great question, and yes.  Commulite comes under BS 50171 ‘Central battery systems’, and it is imperative that at least one circuit is wired with FP100 1.5mm2 singles.  For new systems, we recommend that all cables are FP100.  If an existing system has recently been rewired, we recommend that the existing cabling is left in place, but one FP100 circuit is drawn into the conduit.  This is easily achieved by using the existing ‘Earth’ as a pull through for a pair of FP100 1.5mm2 singles, for the emergency circuit.

Why do I want my emergency lights to run for 9 hours instead of the statutory 3 hours?

For one thing, it makes it future-proof. Also, our lighting will run all night in emergency mode, very handy in a care home or power cut situation, and great for rural installations.  Furthermore, following a statutory 3-hour annual battery check, most emergency light fittings are unable to guarantee emergency light capability until the batteries have recharged.  This effectively means the building should not be used until the emergency back up capability is restored.  Not so with Commulite, after a 3-hour test we still have 6 hours emergency capability left.

Does your ‘maintenance free’ claim apply to both  general lighting and emergency lighting ?

Our system is fit-and-forget and maintenance free, with tamper-proof seals on all fittings and no user serviceable parts contained in the system.  We provide a timed test switch for emergency testing purposes, however, as the lights are visibly on there is no need to engage the emergency mode to ascertain that they are working.  The remote testing module automates testing and logs all results, and sends a text or email to alter you or your maintenance team to  anything that requires attention.  The system carries out the checks and displays that everything is ok on the indicator panel.
