Point/Counterpoint: LED Tubes or T8 Fluorescent Tubes

Posted by on Aug 1, 2013 in Questions & Answers, LED | 0 comments

I love LED lighting more than apple pie, puppies, and a day off from work combined. Still, I Dr. Bulb, LED super enthusiast, understand that LEDs are not the solution for everything and some LED products are not up to snuff. For instance, LED retrofit tubes are not adequate replacements for T8 fluorescent tubes. Despite how some of my other blogs have appeared,  I’M NOT BLINDED BY MY PASSION! LEDs work best in...

Is LED Lighting Harmful to Our Eyes?

Posted by on Jul 24, 2013 in Questions & Answers, LED | 0 comments

Whether it comes from the sun or from high bays, light is my absolute favorite thing. Sadly, it can be dangerous if we’re exposed to an excessive amount or the wrong kind. Although there are six defined optical radiation hazards, the only one that applies to LEDs is blue light hazard. This information leaves us wondering if LED technology is just too good to be true.  Are LEDs more damaging than other light sources?...

LED Lighting for Hospitality Sustainability

Posted by on Jul 10, 2013 in Questions & Answers, LED | 0 comments

When visiting LightFair International this year, I made an important discovery: a hotel’s corridors are illuminated 24 hours a day. And not just dimly lit—they are as bright as a department store. Most wouldn’t think twice about such an observation, but I, Dr. Bulb, could only think about the energy the hotel must be using for lighting! I later learned that hotels have 24-hour burn areas where they’re required to...

It Hertz Just To Think About It!

A question was recently submitted for Dr. Bulb about how electrical power frequencies differ in countries. A long time ago, before I, Dr. Bulb was born, a great electrician by the name of Nikola Tesla calculated the most effective electrical power frequency for home use. This frequency is measured in Hertz (Hz). Through many experiments, Nikola came to the conclusion that 60Hz was the most effective frequency and shortly...

Why would I pay more for LED?

Posted by on Feb 7, 2013 in Questions & Answers, LED | 0 comments

LED lighting offers a multitude of benefits.  Most of these benefits stem from LED lights remaining consistently cooler than average lamps.  LED fixtures last on average 50,000 hours.  Without constantly intense heat the components tend to last longer. Additionally since there is not a huge amount of excess heat we can gather that the lamp is very efficient, not losing energy to heat and instead converting that energy...

What is the kelvin temperature of a lamp?

Posted by on Feb 7, 2013 in Questions & Answers | 0 comments

Kelvin temperature refers directly to the color of the light coming out of the lamp. The Kelvin does not change or affect the amount of light (lumens) being released from the bulb, nor does it directly correlated to the Color Rendering Index (CRI) of the bulb. Kelvin temperature simply refers to the color temperature you see when looking at or around the bulb. Kelvin temperatures typically range from 2700K to 6500K. 2700K...
