According to SCL Direct website a 28 watt 2D lamp has an initial lumens output of 2050.
Depending on the brand, it will give about 18.000 Lumens and equals a 100W HPS lamp
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.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
It will probably be stated on the packet, but I doubt it will be higher than the standard bulb which is about 1200 lumens.
About 300.

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 18watt plc fluorescent tube renders 1800lux
Incandescent bulbs give about 10 lumens of light per watt of electric power Halogens give about 13 lumens per watt CFLs give about 50 lumens per watt So it depends on the type of bulb.
There is no direct conversion . . . different types of lamp bulbs put out different amounts of light per watt.
This is roughly 500 lumens
700 lumens
