If the choice is between different types of multi-chip I would personally prefer to use 10 watt or 20 watt chip. With the Meanwell driver you mention you will not use 50-watt chip completely. They usually need about 1.7 A of current to provide what they should (there is variation but it is usually between 1.7 to 3 A).
But the main reason why I would choose lower effect is that with dimming and variation of color temperature, you get a much better and varied light patterns. Lens or not depends on. I would probably use the lens for some white to give "Hot spots" but not for the blue
With 10 watts, you can use the driver fully and if you set the current to 900 mA, you will be able to have five chips in series per driver. I would also mix different Kelvin - for example, 10 000, 16 000 and 20 000 among the 5 white. Among the 5 blue, I'd try to get different wavelengths such as 420, 445 and 455 nm. With what I know today I'd probably also want to consider instead of 10 watts using 20 watts. They are essentially the 10 Watt, but you can use up to 2 A at them if you wish. With your drivers so it would be possible to use the maximum current (1.3 A) of the driver and then get about about 14 watts from the chips. drawback is then that you can only have 4 pieces in a series but the advantage is that you in the future may replace your drivers and have a much higher effect from your chip.
@ Mikez104: Although in your case I would look at the possibility of using the chip to lower effect in order to achieve a maximum light patterns.
Bcamp: 1) It differ between the different chip´s. Read the descriptions of the current chip.
2) Most likely, but personally I would chose a chip from the same provider you selected the driver from. Their chips are better suited to our needs, even if they are more expensive
@Decadence: See my answer above - you can mix and match however you like. My suggestions above are based on my personal taste but if you prefer two main sources of your light and add the chips with less effect and temperature / wavelengths to get a good light pattern (for you) that's fine. There is no right or wrong, it's just common sense
@ TropTrea: The lenses of multi-chip has a diameter of about 8 cm (3.15 ") compared to approximately 1 cm (0.39") for the lens of 3 watts. This provides a wider beam pattern and not the same risk for spot lighting. A 60 degree lens provides at 50 cm (20 ") a light beam having a base diameter of about 70 cm (27.5").
