LED technical Power consumption, size and brightness. 70 cm RGB rigid strip: 7.2 watts. 30 LEDs 12V DC 60 Lumens. L700 x W8 x H4 (mm) Single colour flex strip: 1.5 watts. 24 LEDs, 30 Lumens. 12V DC. L360 x W19 x H16 (mm). 2-pin power connector.
When calculating power usage to match a transformer always leave 20 % in reserve. For example 8 x 6 watt rigid strips will consume 48 watts. Add the reserve of 20% - 6 watts - for a total of 54 watts. In practice this means you would need a 60 watt transformer. 2 x 6 metre single colour ribbon flex tapes will use 90 watts: add the 20% reserve 18 watts total 108 watts. You will need a 200 watt power supply. |
