Overview of the characteristics of mercury lamps of the DRL type
First of all, it should be noted that the decoding of the marking of the DRL bulbs is as follows: “D” - arc, “P” - mercury, “L” - luminescent. These light sources are most often used for lighting industrial and technical premises, which is associated with their high light output and energy-saving properties. In everyday life, their use makes almost no sense, because There are safer and more efficient LED bulbs. However so that site readers Elecroexpert We knew what these products are, then we will consider the most important technical characteristics of the DRL lamps, providing a short description and all the necessary parameters in the table.
So, today in everyday life arc mercury lamps of the following denominations are used: DRL-125, -250, -400, -500, -700, -1000. The number in the marking indicates the lamp power in Watts, [W]. As for the remaining parameters, the most important are:
- Base Type threaded, size E27 or E40.
- Luminous flux from 5900 to 59000 Lm.
- Service life (service life) from 12 to 20 thousand hours.
- Operating voltage: 95 to 220 V.
- Light output from 47 to 59 Lm / W.
- The emission spectrum is bright white light.
- Color temperature 3800-4200 K.
- The operating temperature is allowed below −25 ° C, which is one of the main advantages of mercury vapor lamps of the DRL type.
These technical characteristics of arc mercury lamps are the most important. We also recommend that you review the descriptions of the parameters of the main brands: from DRL-125 to DRL-1000, which we provided in the table:
That's all we wanted to tell you about the most significant technical characteristics of DRL lamps. We hope that the provided parameters have come in handy for you in your calculations and in choosing the right light sources!
