About the Blog

LIGHT TALK , A day in the life of light

In 2009 I decided to undertake to blog for 365 days, every day of the year, about y experiences as a professional lighting designer through my practice. To reflect the educational  but light hearted nature of the blog I named it “Light Talk“. By the end of 2010 I completed the task without missing a beat, whether snowed in in Northern China or travelling continents to the other side of the world. The first 365 days of blogging have resulted in a very rich pool of thoughts, experiences and events in relation to the lighting design profession that has been read and commented on by many in the industry. The blogs are currently being compiled in a book that should see the light of day by the end of 2011.

After a well deserved break and encouraged by the feedback received from friends and colleagues in the business  I have decided to continue with Light Talk “Season 2”. Like in season 1 I am sharing my thoughts and experiences in the lighting design world with friends and colleagues on the net, this season with a new feature, “Light Watch“, in which I high light places of interest, new developments in the lighting industry or special lighting related events. But I am taking a more relaxed appraoch this time, I still blog on a daily basis, but on work days only. There is life after work 🙂

Readers are encouraged to engage with the subjects and comment on the blog directly or communicate with me privately

Happy reading.

  1. An interesting Article about LED Overheating. We have a curious problems that seems to mirroir yours. Hacel Elitos flashing on and off. They are in pairs sharing the same interface the pairs do not share the same problem. Some flash on and off some freeze and wont dim. When depowered and allowed to cool they seem to behave correctly.

    Did you have further issues with the Philips in Singapore and confirm the problem to be overheating?

    Many thanks Des George

  2. Dear Des, thanks for your comment. I am not familiar with the Hacel range but I would venture to say you have the same issues which are mainly lamp-transformer-dimmer related. We also found that same lamps in the same circuit react differently pointing to a localised issue with the lamp. In our case it could be batch issue. deterioration over time, we don’t know yet. Philips is taking the faulty lamps back to their factory for research and will let us know in due course what they find. It is a serious problem as it affects the general impression people have of LED. If you are using the fan cooled MR16LED lamps from Philips it is likely that the fans are at fault. By not properly working the lamps overheat then the thermostat automatically switches them off, once cooled down they ignite again. You may want to check that and best to get the manufacturer involved also for warranty reasons
    Good luck
