Skin inflammation (dermatitis) sometimes develops around a venous ulcer. Non-venous skin ulcers are less common. For example, a skin ulcer may be caused by poor circulation due to narrowed arteries in the leg, problems with nerves that supply the skin, or other problems. The treatment for non-venous ulcers is different to that of venous ulcers. The rest of this leaflet deals only with venous leg ulcers.
But with the new lumen measurement, you can know exactly, without guessing, the brightness of light a certain number of lumens will produce. Let's consider some examples that compare and convert watts to lumens: â¢ 1  A 40-watt incandescent bulb equals around 450 lumens. â¢  A 60-watt incandescent bulb equals 800 lumens.
Correct with the lumens comment. Check the lumens when you buy the light bulb and make sure not to exceed 65 watts (this is standard rating but check your lamp socket, it will have the rating on it). Source(s): Worked in lighting at Lowes for 2 years. Todd L Â· 7 years ago. Thumbs up.
