A retrofit LED lamp is a more cost effective solution than replacing the entire luminaire. Plus with LED technology developing at such a rate, it can make economic sense not to invest too heavily in technology that could be out of date within five years.
SON and SOX lamps both require maintenance and based on 10 hours per night service will typically need replacing every 8-10 years, where as our LED retrofit lamps have a service life of over 13 years!
Plus our LED retrofit lamps can be installed as part of your re-lamping schedule saving £££’s in installation and future maintenance costs.
By installing our retrofit LED street lamps you can up cycle your existing street lights and keep the aesthetics the same. Whether it's a heritage lantern or a Philips, Thorn or SOX lantern, we have a retrofit LED lamp that will fit.
Typically a 38W retrofit LED lamp with an output of 3,889lm at a colour temperature of 3,000K would replace a 100W SON lamp with an output 10,700 lm with a colour temperature of 2,000K and produce a similarly lit street.
We offer 3 colour temperatures: warm white (3,000k), neutral white (4,700K) and daylight (5,700k). This will allow you to increase the “whiteness” of the light produced without changing the whole luminaire.
It’s worth pointing out that the reflector and lens in the existing lantern will have a bearing on the perceived light levels and we recommend a conducting a trial to achieve the best results.
LED retrofit streetlamps use less power than their SOX or SON alternatives. By investing in our LED retrofit solutions immediate carbon and energy savings will be made.
SON lamps are very easy to upgrade to LED. Simply bypass the ballast, screw in the new LED retrofit lamp in the existing lamp holder and you’re done.
SOX or LPS lamps are easy to upgrade too. Remove the existing gear tray, replace the existing ballast with the supplied LED driver and install the retrofit LED lamp into the lamp holder.
