Recent insight from Healthcare Purchasing News makes a compelling case that hospitals need to bring technology and innovations into the surgical suite (April 2018).
Let’s take a deeper dive into the key innovation in surgical lights: the introduction of LED. As laid out in HPN, “surgical lighting has overcome most of the drawbacks from halogen, lowering power consumption and temperature and providing better quality lighting closer to that of natural daylight.”
The LED revolution is giving providers better options in surgical lighting. To better understand LED vs. halogen, the surgical lighting experts at Sunnex advises stakeholders to better understand the difference between lumens and watts.
Think Lumens, Not Watts
We typically buy things based on how much of it we get, right? When buying milk, we buy it by volume (gallons). So, why should light be any different? For decades, we have been buying light bulbs based on how much energy they consume (Watts) — no matter how much light they give us (Lumens).
What’s a Lumen?
Lumens measure how much light you are getting from a bulb. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light.
Lumens are to light what:
- Pounds are to bananas
- Gallons are to milk
Lumens let you buy the amount of light you want. So, when buying your new LED Lamps or Fixtures, think lumens, not watts.
The brightness, or lumen levels, of the lights you need may vary widely, so here’s a rule of thumb:
- To replace a 100-watt incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
- Replace a 75W bulb with an LED bulb that gives you about 1100 lumens.
- Replace a 60W bulb with an LED bulb that gives you about 800 lumens.
- Replace a 40W bulb with an LED bulb that gives you about 450 lumens.
