    Mono-spectrum (50w more), or poly-spectrum (50w less)?

    2'×4' bloom scenario using E27 LED... 1 spectrum (50w more)... 493w [100% - 3000k](80CRI) or... Mixed spectrum (25w less)... 468w [11% - 6500k](80CRI) + [89% - 3000k](80CRI) or... Mixed spectrum (50w less)... 442w [23% - 6500k](80CRI) + [77% - 3000k](80CRI)
