Magnifier series are F-500A,F-500B,F-500C,F-500E,F-500F,F-500G,F-500H,F-500I (including green glass and white glass,B is the last serial number of white glass such as F-500AB).

These magnifier matches 12W cirle fluorescent lamp(type D). 14W(2x7w) U shape fluorescent lamp ( Type F,G,H,I), 22w(A,B,C,E). Its active arm is a special design. Which can be adjusted conveniently and avoid magnifier's vibration interfere. Our magnifier is used with USA's updated ballast circuit,power can reach more than 0.9, the current flowing is less than 40%,which accords with IEC standard.

B) Parameter

1. Voltage: 220V + 15%/-30%  50HZ/60HZ  110V±20% 60HZ

2. Power: λ ≥0.93

3.Current flowing: THD< 40%

4. Warm-up time: tp≤1.5 second

5. Lumen: Lm≥0.95

6. Protector: can protect the over current flow in abnormal circumstance.

7. Lens:A,B,C,E is φ127mm round lens.

C) Usage scope

Magnifier series can be used by circuit board test,stamp collector,infirmary,beauty parlor,readeramateur,engineer. If for long time observation,rectangle 177x113mm is a better choice because its shape change is smaller than round 127mm and can be felt comfortable for a long time observation. White glass is of high definition and more comfortable than green glass.

D) Notice

1.Before usage,please pay attention whether the power supply voltage is the same with actual voltage or not.

2. When changing magnifier's direction and position. If the adjust arm is too tight. Please loose a little. After adjusting well the direction and position. wrest the arm tight. Do NOT force it to move. which can cause parts broken.

3.Magnifier series needs a warm-up start. After you turn on the power, the lamp will warm up around 1.5 second and the lamp begins lighting normally.

4. It has protector when the lamp occurs with non-lighting etc. malfunction. The electron can self turn off and lock up until the power is turned off.
