20W CFL lamp details and specifications
A quality 20 WATT Compact Fluorescent lamp suitable for many lighting
applications using a 12v or 24v DC power supply (as the case may be). Ideal for areas requiring energy efficient lighting such as: Remote Workshops, Marine and 'off grid' Solar powered homes, Caravans and remote locations including; Farm buildings, Barns and Stables and portable camping lamps. Lamps are available
in 'ES' Edison Screw fitting.
SAFETY 1ST... Please ensure the correct rating of cabling is
used throughout when installing DC lighting and other circuits. Very
long cable runs may require high grade, high amperage cables in order
to prevent excessive voltage loss, especially when using multiple lamps
on the same cable run. All circuits should be fitted with a suitably
rated safety fuse in order to prevent fire in the event of short circuit.
Use of proprietary lamp fittings is recommended wherever possible to
protect and prevent the ingress of flying insects, spiders and damp
where lamps may be exposed in external / exterior light fittings.
Note: 12v or 24v 'AC' transformers must not be used. If using a DC regulated transformer, please ensure that it has enough power reserve for your
application. We recomend at least 20% power leeway for reliable starting. For any remote application, we recommend the use of Lead Acid or other quality Rechargeable batteries and / or using a solar 'PV' panel & regulator to replenish power as necessary.
Fitting notes:
1) Using BC / B22 light fittings - If your lamp does not illuminate, it
may need removing, turning 180 degrees and re-fitting as they are polarity
sensitive.
2) ES / E27 - Centre contact is + positive
3) All lamps are reverse polarity protected so that there will be no
damage if polarity is incorrect for your light fitting (if lamp does
not illuminate remove and refit B22 or change over supply cables on
E27 fittings
Note: Actual wattage may vary by +5% / -10%
