ok, let me explain details to you again.
1. SPT and EFR laser tube is same price for us, if EFR is better, why we still choose SPT C series laser tube?
we are fool? because the quality of C series laser tube is better.
2. C series laser tube is cheaper why it is better?
C series laser tube is seal by plastic, its tightness is better, co2 and other gas can stay inside longer.
Most of laser tube manufacturer want to earn more money, they have to produce new model for their customers.
S series and EFR ZN laser tube is seal by metal, their shapes look advanced and pretty, and these manufacturer
advertise that these tubes is better, and lifetime is about 10,000 hours.
However, it is not a new technology. But their advertisement is very successful, because most of people trust it.
all customers order the machine from us, when we talk about laser tube, I will explain that our laser tube lifetime
is 2,500~4,000 hours, not 6,000, 10,000 or higher. this is offical data.
if you are very lucky, maybe your tube can be used for about 10,000 hours, but the probability is very small,
because most of tubes are gone when they are produced, and 2,500~4,000 hours is average lifetime.
if you use the tube that without testing, its defective probability is very high. However, we still can't promise that
its quality is no problem even though the tube pass our testing. The fact is that these tubes are not good enough,
we just try to find "not bad" tubes from these bad laser tubes.
this is why we provide 6 months warranty for laser tubes, some customers think that it is short, but we can't find
better manfacturer in China this moment.
3. Most of customers know RECI laser tube, is that better? I don't think so. (we have visited their factory, RECI,
EFR, SPT, SP etc, their principle of production is the same)
4. usually, most of customers will accept our suggestion when we explain these reality to them.
and this year, we sold 2 EFR laser tubes and 1 RECI laser tube, all of them are defective.
and I promise that we have tested it before we send it out. (we don't do last test because of time limited)
except these 3 tubes, our other machine install SPT C series laser tube, and only 2 tubes are gone.
5. and I have promised that if this SPT C series laser tube is gone again, we can accept your advice.
I think we can solve this problem easily if you listen our suggestion.
