itu Lm = Lumen .... measurement of intensity of light or luminous flux intensity. So lebih tinggi lagi terang. Tapi comparing 11000Lm dengan 10500Lm not much a different. Lagipun ini nombor is measured at a few centimeter dari the bulb. Yang mustahak is the colour spectrum yang the corals nak absorb and grow accordingly.
