- • MR16 is not compativle with Electronic Transformer
Our LED Spotlight can compatible with common market, and here list some famous brand that we've done the
Electronictransformer compatibility test:
We shipped out batch orders this LED Spotlight to Finland, Israel, Australia, Switzerland, Thailand...ect., so far
haven't any complain for the compatibility problem. However, there are some samples we shipped to Australia,
they reflect the compatibility problems only for 5w spot light.
As we don't know what's your local brand of transformer, we can't guarantee 100% compatible, so we suggest
you try to get some samples to test your marketing first.
In order to solve better the compatibility problems of transformers, our R&D is developing a matching transformer
to achieve 100% compatible, and it will be comes out around the end of March.

- • The 10W power dropped to 7.5W after lighting on a while
Please go on testing, if after the long time testing, the power hasn't gone down to 7.5W, that will be still normal
to our spot. As our R&D do a special design for the temperature protection in the spot, which keeps the power
and luminous decay can be under control. Another words, it's not real decay, when the
environment temperature
come lower, the power and luminous will be high again, normally the power region is 7.5W-10W. As you know,
now on the market, for most high power lights, the light decay cannot be controlled, and the result is real fast
fading or burnout, but ours will not. So, sincerely hope this phenomenon now is explained out and could be acceptable.
- • customer complain some of them have noise when turn on
This problem should mainly due to the electronic transformer compatible property.
I have conducted this question to our R&D, and if it’s convenient for your customer to change a transformer
to the spotlight? As maybe if change one then it will work well. Our spotlight has been tested can compatible
with most transformers, however maybe still cannot work well with few ones. Our R&D is still continuing their
works on it to do improvement, having idea to take the driver out from the spotlight and combine it with the
transformer, then we can offer all together to you, any news about this I will keep you updated.
- • The price is too high:
Our company takes this product as our most powerful product, which we aimed to push to the world since last
autumn's HK Fair. So all materials we chose for this product are with high quality approved, like the CREE led,
IC from UK, high quality capacitor, special designed driver etc., all these keep the cost of this product is high.
However, price is flexible based on the quantity, and believe once we open cooperation together, our company
will have the capacity to offer better profit price for you. And at the beginning, we sincerely welcome you try
samples first, and if you feel it is really a potential product on your market, then believe price will not be the first
problem to our cooperation, as price is always negotiable.

- • May I have free samples?
We sincerely hope could do cooperation with you but it’s really feel very sorry on the demands of free samples…
Our company have the idea of cherish each pc product, that’s why we don’t keep sample stock, we each time
newly produce them with our material, labour, machine etc., and once finished we will test them 24 – 48 hours
before delivery, these links all produce cost. So it will be impossibility to move the production line and ask them
produce products for personal freely, only our account’s production order can move them, and our account
never key out free production order…
We hope the best we can do is supply our best product to our partners, but not do free samples at a beginning
cooperation, that from some extent also a sincerity we want see from our new customers. Really hope your kind
understanding on it.
- • How to handle the heat dissipation problem? Keep 7w/10W in such a small shell?
Almost every people have this doubt the first time they see this product, however this point is just happened
to be our technology advantage.
First,the driver inside the spotlight is specially developed by our R&D with over 1year time, during that time
the temperature bear possibility testing of the driver be continued, and the testing performance is approved good.
Second, the LEDs used in the spotlight also own high quality like CREE, OSRAM, and also one style our R&D
developed out, these leds can bear highest 120鈩? however the highest
junction temperatureon the chip of the
spotlight is only 95-100鈩? so there have no problem on the leds.
Besides, our spotlight shell also unique designed with Gaps and vents, which keep the heat inside can be quickly
conducted into the air, that’s also why when the spot is on lighting, the surface of the shell is very hot.
So from above three aspects, our R&D have solved the dissipation problem during their initial design on this product.
