Denver7 traffic anchor Jayson Luber says he has been covering Denver-metro traffic since Ben-Hur was driving a chariot. (We believe the actual number is over 25 years.) He's obsessed with letting viewers know what's happening on their drive and the best way to avoid the problems that spring up.

The ILT2400 is the most advanced hand held light meter and optometer on the market today. ILT’s Accuspan software automatically sets the averaging while rapidly measuring over 8 decades of light intensities.  The internal software allows customers to capture a peak as brief as 100μS and to store up to 16 readings per second.  The color display works in both landscape and portrait mode.

The ILT2400-UVC  is specifically configured and calibrated at 265 nm to measure the UVC levels where most pathogens, including the COVID-19 virus, are inactivated (See graph above).  With the touch of a button the ILT2400-UVC will do the following:

Mary from Denver writes, “What’s driving you crazy? Hi Jayson, after reading your article regarding the highway onramp lights, I have a question for you. If you are coming up to the light, no one is in front of you or beside you and by the time you get there, it turns green, do you need to stop? My son got a ticket today for doing so, and the officer said "Well, you didn't even hit your brakes, that's why I'm giving you a ticket". It's a 4-point ticket, which in my view is totally excessive for an onramp light that was GREEN when he went through. Wondering your thoughts on that?”

Josh Lewis from the Colorado State Patrol told me, “Because I don't know the exact circumstances, I wasn't there, this will largely come down to officer discretion based on the situation. Metered lights also have signs near/before/on them that indicate a vehicle needs to stop, in addition to the red light itself, when active. The intention of these lights is to filter in traffic to the main highway in an effort to avoid congestion, hence if the lights are activated, they need to be followed like any other traffic control device. Given how quick the green is, the driver should always be prepared to stop at them, but again, not knowing exactly what took place in the moment, I cannot articulate as to the officers reasoning in issuing the citation.”

The built-in 12 mm diameter cosine receptor is protected by a magnetic rubber cap that remains attached to prevent loss or damage. The toggle buttons allows the user to easily scroll up and down to view readouts between lux & foot candles, spectrum, CRI, CCT, W/m2 PPRF, umol/m2 *s and more.

Ginger Delgado with the Arapahoe County Sheriff’s Office told me, “The only time you can go (and don’t need to stop) is if the light is green at the EXACT moment you cross the light. Something seems a bit fishy because there had to be some red involved or I doubt the officer would have ticketed the guy. Since we weren’t there, it’s hard to speculate what happened. It sounds that most likely the person saw the light was green but at some point, it turned red.”

Since my opinion isn’t worth anything when it comes to getting or not getting a ticket, I asked your question to several law enforcement agencies who patrol ramps with meter lights.

Kurt Barnes, technician with the Denver Police Department, told me, “Colorado Revised Statutes 42-4-604 defines a driver facing a steady circular red signal shall stop and the same driver facing a circular green signal may proceed straight through. Officer discretion is important given the variables that can exist at these traffic signals with traffic volume and flow.”

The ILT2500 is the most versatile light measurement system ever designed by ILT.  It combines the ease-of-use of our hand-held, portable optometer, the measurement range of a research/lab radiometer, pulsed light profiling similar to an oscilloscope, and the spectral measurement capability of a spectrometer.  Together with our NIST traceable / ISO 17025 accredited calibration, and a wide array of sensors, input optics, integrating spheres and the new MEMS 880 spectrometer head, the applications for the ILT2500 abound!

The ILT350 light spectrum meter has three measurement speeds including Fast (0.5 s), Slow (2.5 s) and Auto (0.5 – 27 s) depending on light intensities (20 lux to 100K lux). The spectral resolution is approximately 10 nm with an accuracy of ±3 nm. Relative spectral distribution data is exported in 1 nm increments using the light meter software.

Typical applications include new light fixture installations requiring proof of minimum or maximum light output, confirmation of adequate lighting in factory production areas, in public building stairways and corridors, to meet OSHA lighting compliance, etc.

The hand-held ILT350 Chroma Meter is an illuminance spectrophotometer designed for portability, quality and ease of use. The housing design is ergonomic and light weight yet packed with features such as a built in full color display. Extensive data capture and analysis software, rechargeable battery and internal data storage. The menu buttons are intuitive and easy to use.

The ILT2400 supports numerous light measurement applications including Audience Scanning Laser Safety, General Purpose Light Measurements, Research, Sterilization/UVGI, Solar, Photoresist – lithography, Optical Radiation Hazard, Phototherapy, Photo-Degradation, PPF & PPFD Plant Studies, and more.

It’s not enough to trust the manufacturer’s specifications.  You must verify that the system you’re entrusting the health and well being of your patients to is doing what it says – deactivating germs and killing pathogens.

As with many scenarios when driving, doing something wrong is many times up to the discretion of the officer patrolling the streets and their interpretation of the law. The wonderful thing about our systems of law and order is that the ticket is not the final say. It is technically a summons to court. Your son can, and should, make his arguments to the traffic judge and see what the judge rules. Most people just sign the ticket, basically admitting guilt in exchange for a lesser penalty and lower fine. Since law enforcement opinion that I mentioned in this story is mixed, your son might be able to persuade a judge to see the situation in his favor.

Crystal Dean, operations support manager with the Greenwood Village Police Department told me, “Based on this scenario, there would not be a violation.”

This is a tricky one as it seems that the legality of this move is up to the discretion of the officer that sees it happen. My feeling is that any driver using a ramp that has an active meter light that is flashing red and green should approach slowly enough to stop if the light is red but not be ticketed if the driver is rolling through when the light is green.

The ILT10C Light Meter is ILT’s most economical light measurement system. The ILT10C reads out in either Lux or Foot Candles in the human eye Visible range (400-700 nm) and is designed for use in a wide variety of applications needing a quick, accurate light measurement.
