Unlike KVANT, many manufacturers use numbers in their product names, but these don’t always correspond to the actual power output of the product.
A ‘6000’ model designation doesn’t necessarily mean that the laser you’re looking at produces 6 Watts of laser light. So that you know what you are paying for, always remember to check the minimal guaranteed power output of the system.
SOMETIMES LESS REALLY IS MORE.
2. Scanning speeds can be deceptive.
The speed of the scanning system is measured in points per second (pps), normally at a 7-8 degrees scanning angle, i.e. 30.000pps@8 degrees. And this could be sometimes interpreted as 60.000pps@4 degrees or 100.000pps@2 degrees.
The fastest scanning system we currently know has a maximum scanning speed of about 90.000pps@7 degrees.
ALWAYS CONSIDER THE ANGLE AT WHICH THE SPEED WAS MEASURED.
3. How much power do I need?
Each milliwatt of quality laser power is relatively expensive so don’t waste money buying more power than you need.
Equally don’t under specify - that’s actually the worst thing you could do. The main factor here is the quality of the beam. The tighter and smaller the beam, less power is needed.
Here’s a general power guide based on good beam quality using our KVANT lasers when conditions are ideal:
• Small indoor venue - up to 1500 people: 500mW - 2000mW - Clubmax 2000
• Medium indoor venue - up to 3000 people: 2000 - 6000mW - Clubmax 6000 FB4
• Large indoor venue - 5000 people or more: 6000mW - 10W - Clubmax 10 FB4
• Medium size event, open air stage, small festival: 10 - 20W - Spectrum 20
• Large outdoor events, festivals and stadiums: 20W & upwards - Spectrum 33 RGBY
4. Do I need full or single colour laser?
Green lasers are highly visible and reach further than any other colour laser beam at the same power, so green lasers can be a great option for large outdoor events and long distance advertising.
For everything else full colour lasers are most versatile and give the best audience experience. So for 95% of applications you’ll want a full colour laser system.
WE SUPPLY AND HIRE ALL TYPES OF KVANT LASERS.
5. Manufacturer vs. Importer/Assembler
There are many importers and assemblers who call themselves manufacturers. The reality is that you could be paying big money for cheap and low quality re-branded imports.
WE DEVELOP, DESIGN & MANUFACTURE EVERY KVANT LASER IN-HOUSE.
6. Europe, China or elsewhere?
If you are serious about lasers and if it is important to you that you can rely on your equipment, then lasers from the Far East are not exactly what you are after. The cost of any repairs due to high shipping costs and delays can easily cancel out the initial money saved. Also your reputation could be at stake.
YOU GET WHAT YOU PAY FOR.
7. How much should I spend?
High quality, low power laser systems will cost anywhere between £1000 to £5000. The biggest can be even over £100k.
Quite often the middle ground is the correct option and when it comes to the cost of lasers we are exactly there.
And whatever size laser you need there’s a competitively priced KVANT laser that’s made for the job.
DON’T UNDERPAY, DON’T OVERPAY.
8. What about life span?
You may save some money initially on a cheaper laser where some of the colours are based on older DPSS technology or Diode technology of lower quality.
When we say older DPSS, we don’t mean all DPSS. There are superb quality DPSS modules round, but they cost thousands and normally you won’t find them in show laser systems.
Many Far East manufacturers specify a 10.000h life expectancy for DPSS and Diode laser modules and while this might be true in rare cases, we have never experienced even 300 hours when testing them.
REPAIRS ARE COSTLY AND COMPLICATED.
9. And what about laser safety?
You would not want to get in trouble with authorities or harm someone’s eye sight. Make sure the laser you get fulfils all european safety requirements. And not only on data sheet.
