We don't always disclose this information. What we can say, however, is that we often do NOT use well-known chips such as Osram Oslon or Samsung LM301. In the seriesX PWR, for example, we use the older Samsung LM281. We see the fixation on the chips used as a marketing trend that we do not want to follow. Ultimately, it is not the components that are used in the lamp that matter, but rather how long the lamp lasts and what quality of light it produces. The Samsung LM301, for example, is an excellent chip. But that is irrelevant if it is installed incorrectly. With LED chips, there is always a connection between the forward current (mA), the output power (PPF or lumens) and the service life. For example, a chip can achieve an efficiency of 4.0 μmol/J at 700mA and an efficiency of 4.4 μmol/J at 350mA. Therefore, it is better to use two chips at 350mA each, but this is more expensive. A chip at 350mA also has a longer lifespan than one at 700mA. Sometimes a similar, cheaper chip at 350mA may not achieve 4.4 μmol/J, but only 4.2. But 4.2 is still better than the 4.0 of the "brand chip" at 700mA. As a developer, you then have the choice of buying the more expensive "brand chip" for 10 cents or two of the others for 6 cents each. We usually choose the second option. We buy the cheaper chip, double the quantity, and run at half the power. This leads to more efficiency and a longer lifespan - but without exploiting the marketing potential of the chip manufacturer's brand name.
