Being as though I might end up at the focus of their attention, I made sure that they got what they wanted. Surgeons have to have 5K Kelvin lighting to actually see what they are doing. WHY? With trashy orange lights, blood and several internal organs, disappear. Operating theaters use only 5000 degree Kelvin lighting. The following are 1600 lumen LED floodlights, outdoor rated – waterproof, 5000K color temperature:Īfter working ‘a while’ in plant engineering in a hospital I learned a few things about lighting. Although I don’t use the dimming feature, it has been said that a dimmable LED floodlight functions better with the RAB Stealth-360 outdoor motion sensor lights (the best sensor on the market – which I use exclusively) (My review article linked below). Also, the following LED floods are dimmable. There are far more choices for standard PAR38 flood lights with 5000K color temperature – and even more with 3000K (but I don’t like them as much for security lighting). While the bulb listed above is great if you’re willing to pay for it (I love the 6000K attribute), here’s another choice, and they’re what I’m currently using (because I have a lot of floods and these cost less). 1400 lumen with a flood beam angle of 120-degrees. It’s slightly pricey, but, the color temperature is 6000K (6000K LED floods are somewhat hard to find, whereas 5000K are more readily available). My current choices as of this post update: 6000K That is, assuming you’re using them outdoors. My preference for ideal outdoor security lighting: Floods (rather than spots), at 5000K or 6000K color temperature, preferably 1400 lumen or more (depends on what you’re lighting up though), waterproof, and PAR38 to fit in standard fixtures. My recommendation for the best color temperature for outdoor security lighting: In marketing terms, that would be Cool white (5000K), or slightly bluer (6000K). Okay so let me answer this… Warm white or Cool white for security lights? 5000K – 6000K light produces HIGHER CONTRAST as seen by our eyes.įor the sake of security lighting or flood lights purposed for security, I would go with at least 5000K color temperature bulbs or floods. The visible spectrum ranges from deep red (long wavelengths) shortening through yellow, green, blue, all the way to deep violet (short wavelengths).Ĭolor temperature is measured in degrees Kelvin (K).īest Color Temperature For Outdoor Security Lights What is Color Temperature?Ĭolor temperature is a technical representation of the perceived color of light. The color is our brain’s translation/interpretation of those wavelengths through our eyes. Light is simply electromagnetic waves of various wavelengths within the visible spectrum. Actually, it’s the ‘rods’ and ‘cones’ in our eyes that get the job done. Visible light is a band (segment) of wavelengths that our eyes can ‘see’. Light is an oscillating electromagnetic wave. ( In a hurry? Jump straight to the answer )īut if you’re interested in the “why”, read on… Outdoor Security Lights – Warm White vs Cool White – What’s Best? Quickly, before I recommend the specific best color temperature for outdoor security lighting or outdoor motion lights, let me briefly explain a few things (how it works).
