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.
23 watts. Typically, the output of a 100-watt incandescent bulb is about 1,600 - 1,700 lumens, a measurement of lighting power. Beginning in mid-2011 new labels will be required on light bulbs. When these labels become available, simply look for a lumens rating to choose a replacement bulb. former 100-watt light bulb manufactured on or after January 1, 2011 and sold in California will have to use 72 watts or less. The 72-watt replacement bulb will provide the same amount of light (called lumens) for lower energy cost.
