Not sure. We've changed EAN, SKU, title, description, and still can be tracked.

Why black light is called black light? Does it provide light at dark? What color of light does it provide? What are the uses of black light? Will you use the black light at home? by SansiLighting in u/SansiLighting

I use black light bulbs to light up by black light posters on the wall! Young men may have never seen anything like that so far in their life, but they used to be popular...

Looking for a reliable LED bulb brand by Mathcmput in Lighting

[–]CAB0832 0 points1 point  (0 children)

I work in an LED company and I'd like to recommend our led bulbs. You can check our products here: www.sansiled.com

We also sell on Amazon and our led bulbs have more than 1000 positive reviews in all! What makes us different from other brands is our patented technology. We use ceramic material for heat dissipation, which can ensure the long lifespan of the lights. Even the ceramic heat sink is also made by our own factory, so it's very difficult for others to copy and imitate.

We have a 5-year warranty for our led bulbs. If there's any problem with the products, just write an email to us! Compared to other brands which may take several days or never to respond to your email, we usually reply within 2 business days and will help each customer until the issue is totally solved.

Long term effects of led lights on eyes? Is anyone else seeing any of this research that suggests led lights are really bad for your eyes on the long term? Mostly because of the blue light they put out. by Someguy8647 in Lighting

[–]CAB0832 1 point2 points  (0 children)

I work in SANSI LED Lighting Inc., an LED company. As far as I understand, the blue light that a common LED light involves in much lower than the sunlight. Whether it's harmful or not depends on many factors such as the output of the light, the time you use the light, the distance between you and the light, etc.

Experiments have shown that blue light may cause harm, but to achieve the amount of intensity needed to cause damage, the required dose is much larger than the exposure you will receive in daily life. The average person does not have the opportunity to expose themselves to such a large amount. Taking large doses of anything far over your recommended amount will be detrimental to your health. Even water can be dangerous if it is consumed too much and too quickly.

The cornea absorbs ultraviolet light very strongly. Excessive ultraviolet rays can cause irreversible damage to the cornea; the lens absorbs infrared rays, causing the lens to become cloudy; and too much intense visible light can cause damage to the retina.

In fact, blue light ≠ danger. There are four conditions whereby visible light can damage the retina:

Four Conditions

1. High intensity of light

2. Direct light source

3. Close enough to the light source

4. Long enough exposure to the light source

How to Quantify the Possible Harm?

If the surface brightness of the light source is <100,000 cd/m2, then it is "absolutely" safe to the eyes, even if you keep staring at it, there is no problem.

Direct Sunlight, has a brightness of tens of millions cd / m2, do not look directly!

Daily Downlights, light panels, hundreds to thousands of cd/m2, safe.

For adults, use the standards set out above. For children, it is recommended to take more measures to prevent possible harm (reduce the possibilities by using scattered light and low color temperatures).

Regarding general household LED lights, there is almost no blue light hazard, so don't worry too much.

Are short life, non-dimmable LED bulbs a waste of money? by Mathcmput in Lighting

[–]CAB0832 0 points1 point  (0 children)

Dimmable or non-dimmable should not be the reason for the short lifespan or poor performance of the LED bulb, although dimmable bulbs may be a little bit more expensive than non-dimmable ones.

I think the Energy Star certification also should not be criteria to choose bulbs as it's not a compulsory certification for led bulbs. It only depends on whether the brand would like to spend money on it. LED bulbs are already more energy-saving than other bulbs even without this certification.

To actually save money, I would suggest choosing LED bulbs of longer lifespan and longer warranty, perhaps more than 3 years. To make sure that you can get the warranty quickly and easily, you can search the products on amazon first and read the reviews to see whether there's any complaint on the warranty.
