Lightning hampering new LED street lights

Sensitive bulbs could cost municipalities a fortune

Over the next five years, around 200,000 street lights will be replaced by the far more effective LED bulbs in Denmark, which are expected to save municipalities 70 percent on their energy bills. But already, a pitfall has emerged.

The LED may be affordable and climate-friendly, but they are also far more sensitive to lightning strikes. Lightning strikes in the town of Tim by Ringkøbing in Jutland popped over 100 new LED bulbs around Christmas, costing the local municipality 300,000 kroner to fix.

”We probably need to admit that this technology is more sensitive to lightning compared to the old bulbs,” Henrik Jensen, an operating manager at municipal utility supplier Ringkøbing-Skjern Forsyning, told DR Nyheder.

Millions at stake
According to meteorologists, the changing climate means that Denmark can expect more lightning strikes in the future.

Fortunately, there is a solution available, but the cost of protecting the new LED bulbs against lightning could well run into the millions.

The EU wants its member states to phase out all mercury-based bulbs by the end of 2015.

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
