New for autumn 2011 - the R3 is introduced to replace the M3/X3 units, giving multiple power levels and selectable beam blending - less flexible than the top-of-the-range P51m, but more flexible than the old M3/X3 units.

New for 2011 - the P51m reflector unit, the latest version of the P51, now with a wide range of operating modes available to suit any user's requirements, from maximum flexibility to maximum simplicity.
The P51m is the latest evolution of the classic Bisun twin-LED reflector units with smooth flood and penetrating spot beams, mixable at will into your perfect blend.

Available as a complete caving light with or without rechargeable battery packs or as a drop-in module for existing lighting setups with Oldham or CEAG headsets, the P51m has a maximum light output more than twice that of the preceding P3x series units, giving up to 180 lumens per LED, and a combination of power economy, brightness and flexibility of use that is hard to beat, whether as a great light for regular caving, or a light that can be run with incredible battery life for expedition use.

For people looking for simpler twin-beam units, the S3 has been added to the range to provide the simplest and most economical units for people looking to upgrade FX3s, etc with fixed-power units which are far brighter than the bulbs they replace, while consuming much less power.

The X2 unit (a serious upgrade for FX2/DX2 lights) has been revamped with more efficient electronics, and the price has been reduced.

All the twin-beam LED units from the X2 and S3 up to the P51m use the latest CREE XP-G LEDs for maximum efficiency.
Neutral-white or warm-white versions are available on request for people who prefer them to the standard cool white versions.

Also recently out are the 'Pharos' ultra-compact LED lighting units for cave photography.
