Key Features
- No electrical components inside the lamp housing — compressed air drives an internal generator, so the bulb is de-energised the moment the housing or guard glass is breached
- Positive-pressure air flow purges the enclosure continuously, preventing flammable gas ingress and cooling a broken filament
- Exs II T4 Gb / DIPA21 Ta,T4, 'S' type protection — certified for gas Zones 1 & 2 (IIA/IIB/IIC) and dust Zones 21 & 22
- Nickel-plated brass body with IP67 sealing (stainless steel option) for wet, corrosive tank and pipeline environments
- 24 V / 250 W halogen G5.3 source at 6000-9000 lm, with a 24 V / 50 W LED option rated 30,000+ hours
- Two beam patterns in the range: spot (330637) for distance work and flood (330638) for area lighting

Frequently Asked Questions
Can you supply the full IMPA 330637-330638 range, and are the two codes priced separately?
Yes. Both codes in the series are available as individual line items: IMPA 330637 (BH250B spot type) and IMPA 330638 (BH250D flood type). Each code is quoted and priced separately, so you can order a mixed quantity of spot and flood units on one purchase order.
What is the minimum order quantity for these compressed air safety lights?
As a wholesale and retail supplier we accept both single-unit and bulk orders. Minimum order quantity depends on the variant and destination; send us your required IMPA codes and quantities and we will confirm MOQ, unit price and lead time within 24 hours.
Do you ship worldwide, and can the order be delivered to our ship agent?
We ship worldwide via freight forwarders, by sea or air depending on urgency and volume. If your vessel is better served through a local ship agent, we can arrange delivery to that agent on request — we do not claim direct alongside delivery.
Is the LED version available, and can I order a mix of halogen and LED lamps?
Yes. The lamp is supplied with a 24 V / 250 W halogen G5.3 bulb as standard, and an LED option (24 V / 50 W, 4800 lm, 30,000+ hours) is available. Halogen and LED units can be combined in one order; specify the light source against each IMPA code when requesting a quote.
