What's the difference

only thing i can find is it has to do with how "intense" the light output is for that given light, if it needs to be seen alot and what knot you would want a class 1 beacon, i think the new code 3 led ones are class 1 optics
hope this makes sense

In a nutshell, Class 1 is the brightest light. I can't find the specific info tonight, but I think the range is 12,000-18,000 candela.
Officially, Class 1 and Class 2 (and Class 3) refer to the SAE specification for a “minimum acceptable level of Visual Warning…”.
SAE establishes recommended standards for the automotive lighting industry. SAE is not a Regulatory Agency, but is the recognized industry standard in legal cases.
Typically,
Class 1 devices are utilized on Authorized Emergency Vehicles (Police, Fire, EMS, etc) that are requesting the Right of Way.
Class 2 devices are utilized on Service Vehicles (Highway Maintenance, Construction, Utility, etc) to warn of a traffic hazard.
Class 3 devices are used mostly for Identification and/or Supplemental Lighting (forklifts, golf carts, etc).
Keep in mind these are the minimum requirements, so many agencies/fleets use a Class 1 where a Class 2 would be sufficient, etc.
All of the major brands offer several choices of Class 1/2/3 strobe/LED beacons, and Class 1/2 strobe/LED mini-bars and lightbars.
PM me if you need more info...

In short, Class 1 is bright, Class 2 is not, and Class 3 is only bright enough for indoor use as an indicator light.
Ok did some research on the classification you all mentioned.
So why would a 22 watt beacon be a class 1 and a 25 watt beacon not be?
And how many watts would a 16 joule beacon be?

Dome color and configuration also come into play. Some beacons are not rated.
What are some examples of the lights that you are talking about. Maybe we can be more specific.

Ok here are 2 Class II beacons from ECCO 6750 rated for 10-16 Joules. would like a translation into watts. Customer wants red domes not clear.
And here is a Class I Whelen 800D rated at 25 watts
And here is another Class I Whelen 2022 Rated at 22 watts
Whelen defined a Joule as one Watt of energy consumed in one second.
A multi flash beacon rated in Joules is usually rated adding up the Joule rating for all of the flashes.
A quad flash 9/2/2/2 Joules totals up to 15 Joules.
Usually the higher the Joule rating, the better the SAE class rating.
Red is the worst color for transmitting visible strobe light, so can, but not necessarily, result in a worse SAE rating.
In your examples, the higher Joule rated lights are all class 1.

Well know that's interesting. been trying to find that info for sometime now.
So if the ECCO is considered Class ii why would the offer dome replacement in r/g/b
