Warm or Cool - the choice is yours?

When you first decide to invest in LED lighting one of the main considerations is what kind of colour output is best ? Unlike traditional bulbs LED light bulbs are capable of emitting different shades of light. Most GU10 LEDs on the market are avaiable to buy in either warm white or cool white colours and it’s often only when you plug them in that you can really see the difference. The Osram LED Classic A Active & Relax gives you the best of both worlds by letting you easily switch between different colour temperatures.

GU10 LED Osram LED SST Active and Relax PAR16

When it comes to choosing the colour output of an led bulb the choice is all personal preference and use. WIth the range of Osram LED Classic A Active & Relax you have the choice. If you like the warm cosy glow of a traditional lamp then warm white (2700k) would be the ideal choice, If you want a modern, clean look, or you want a light to help you focus on a task you may prefer the cleaner, brighter feel of cool white (4000K).

If you arrange an urgent delivery, there is still no absolute guarantee that it will be delivered the next day, as, despite our best efforts, courier failure/errors and ‘acts of god’ may still occur. Therefore while every effort will be made to have your goods delivered on time, LightBulbs Direct Ltd accepts no responsibility for any costs incurred as a result of delayed delivery.

Please note that most orders weighing in excess of approximately 1.5 kg and any valuable deliveries are delivered by courier and will require a signature on delivery. Please ensure that you provide a delivery address where someone will be available between 9.00 and 17.00 Monday to Friday to accept delivery. If our couriers are unable to deliver an order due to the address being unmanned, a card will be left asking you to contact them directly to arrange re-delivery.

Please make sure that you always order your light bulbs to arrive well before you need them as costs of cherry pickers and sub contractors are always more expensive than the light bulbs themselves.
