Datacenter and Colocation Discussions

We all know what CFL bulbs are. But few people know about how LED lighting can bring additional power savings to a datacenter.

For starters, LED lighting is slightly more efficient then CFL bulbs. The hidden value is heat output reduction. LED lights have almost no heat output. In a 5000sqft facility using traditional T8 35W bulbs vs LED, this can add up to a difference of 2000 BTUs per hour.

The only limitation to LED is it is still cost prohibitive. For example, a T8 fluorescent bulb is about $6. An LED T8 bulb is about $90. If you run your lighting 50% of the time, then it will take about 2 years to recover the cost from gains in power saving.

Ecologically speaking LED’s are also superior since they do not contain any Mercury. At Quonix, we are planning to convert to LED lighting systems within the next year for our datacenter.
