Flameproof Hand Lamp 10W - 15W
What is a Flameproof Hand Lamp (10 W–15 W)
A “flameproof hand lamp” is a portable, handheld or hanging light designed for use in hazardous / potentially explosive atmospheres (gas, vapour or dust). These lamps are used for inspection, maintenance, confined-space entry, vessel/tank inspection, emergency lighting, repair work in industries like oil & gas, petrochemical, chemical, fertilizers, mining, refineries, etc.
Unlike ordinary lamps, such hand lamps have robust explosion-proof housing, heat-resistant glass, sealed enclosures, and are certified for hazardous zones (e.g. Zone 1 & 2, Gas Groups IIA / IIB / IIC).
They are valuable where fixed lighting cannot reach — such as inside vessels, tanks, narrow or confined areas, or during temporary maintenance/shutdown operations.
Typical Technical Features & Specifications (10 W–15 W Range)
Based on available manufacturer/supplier specs, flameproof hand lamps in the 10–15 W category generally exhibit the following attributes:
| Parameter / Property | Typical Value / Detail |
|---|---|
| Protection type | Ex-d (flameproof / explosion-proof) — suitable for hazardous zones. |
| Certified Zones / Gas Groups | Zone 1 & Zone 2 (sometimes Zone 21/22 for dust); Gas Groups IIA, IIB, IIC |
| Ingress / Weather Protection | IP66 (dust-tight, water-jet resistant) or similar, often weather-proof as well. |
| Housing / Build Material | Die-cast aluminium alloy (often LM6 / LM-6), with epoxy/powder coating finish for corrosion resistance. |
| Lamp / Light Source | LED (commonly 10 W LED or 15 W LED) |
| Operating Voltage / Supply | Often 220–240 V AC for fixed-supply versions; some battery or low-voltage (24 V AC/DC) options also exist for portable usage. |
| Temperature / Ambient Range | Many are rated for operation across typical industrial ranges (e.g. –20 °C to +50 °C or –40 °C to +50 °C in some rugged versions). |
| Light Output & Efficiency | LED versions may offer high luminous efficacy (e.g. 100 lm/W or more) hence sufficient brightness for inspection. |
| Mounting / Handling Features | Usually hand-held; may include a swivel hook for hanging (hands-free) or a handle/insulated grip for portability. |
Some specific protection/standard remarks often apply:
Explosion-proof certification: Many comply with standards like Ex-d / Ex-db for gas atmospheres & are certified for hazardous environments.
Temperature Class: Often rated T6 (maximum surface temperature 80 °C), suitable for many hazardous atmospheres.
IP & Mechanical Protection: Sealed glass + gasket + rugged housing to prevent ingress of dust/water, and able to contain internal explosion without propagating externally.
When / Where to Use Such a Lamp
A 10–15 W flameproof hand lamp is particularly suitable when you need:
Portable or temporary lighting — for maintenance, repair, or inspection operations inside tanks, vessels, reactors, or confined spaces where fixed lighting cannot reach.
Safe illumination in hazardous atmospheres — areas with flammable gases, vapors or dust (oil & gas plants, chemical, petrochemical, refinery, fertilizer, cement, mining, etc.).
Flexible deployment — because of hand-held or hook-mountable design; useful during turnarounds, shutdowns, emergency maintenance, inspections, etc.
Reliable, rugged performance — with resistant housing, sealed enclosure, good ingress protection and explosion-proof ratings to prevent ignition hazard.
