ROI Converting Fluorescents to LED
Rather that post this on Grey Mountain’s topic, I started a new one. What is the wattage and cost difference between traditional T8 or T5 fluorescent fixtures found in RV’s and an LED fixture of t...

What the lamp or fixture states at wattage is usually so incorrect it is almost laughable. They are trapped in a "more is better" claim of wattage.
From desk lamps to light bars to A26 screw in light bulbs the claimed wattage is higher than what reality reveals.
An "18 watt" fixture draws 12.6 watts supplied with 12.00 volts, and if 18 watts is consumed at 15.8 volts, the chips overheat and fail and render almost zero increase of lighting. Without voltage regulation 10-30 volts the wattage remains low until unrealistic input voltages are reached.
So, I suggest ignoring OEM stated wattage and make decisions based on perceived amount of light. It's a real zoo...
