This is roughly 500 lumens
From 20,000 to 23,000 lumens depending on the brand.Average figures:Incandescent: 10 lumens per wattHalogen 13 lumens per wattCFL (low-energy) 50 lumens per watt
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.

Approximately 15 lumens per watt for halogen, so 300 lumens.

Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
About 80 lumens per watt of electric power is normal for LEDs.
A good projector will have 2000 or more lumens, but an LED projector will have much less.
