Q – I have a 2842 light bulb. What is the replacement for this?

A- It depends on which fitting it is being used in.
If it is used in a down light flush in the ceiling you will need the 8722 led light bulb (if you have a reflector within the fitting please remove this for the light bulb to fit – see video)
If this is in another type of fitting please contact our customer services team who will be able to advise the correct replacement light bulb.



Q – Why can’t I get these replacement light bulbs from B&Q etc.

A – All tp24 fittings have been designed to comply with the Building Regulations and requirements for sustainable homes. Our fittings are dedicated and designed to only accept tp24 low energy light bulbs, but the other retailers do not take this approach.  Most of our lights are used by major developers and they have to comply with Building regulations.
Retailers generally supply to end users that are not required to meet the building regulations and usually supply without light bulbs.  Unfortunately they are not willing to stock the dedicated tp24 bulbs.
There are several larger electrical wholesalers that do stock our bulbs and a few online suppliers, but if you purchase direct from tp24 we are able to ensure you get the most advanced models and latest batches.



Q – The replacement for the 2315 light bulb is the 8514 light bulb but there is a big difference in the Watts. Will these be okay to go in my fitting?

A – The original bulb was a 20w compact fluorescent and took a while to warm up.  The new LED light bulb is only 9w but is as bright as the old model and gets to full power instantly.



Q – Why are my light bulbs different colours?

A – To some extent this is related to the price and the nature of LED chip manufacture.  At tp24 we accept a colour tolerance of 125 degrees either side of our optimum.  So if our target is 3000k the chips could be anywhere between 2875 and 3125.  If you get two different light bulbs from either end of this spectrum you will see some visible difference in colour.  We always aim to send light bulbs from the same batch when we pick for our fittings, but if you are replacing from a different batch we have very little control.



Q – Why do you keep changing the appearance of your light bulbs

A – Additional legislation has also forced many changes on the industry, largely for good and generally to the benefit of the end users.  To meet the new legislation the industry quickly moved to SMD – surface mounted diode.  This structure is now using a plastic casing with an aluminium core.  The plastic is a good insulator and the aluminium helps transfer the heat away from the chips.



Q – Why are your lights dedicated?

A – All tp24 fittings have been designed to comply with the Building Regulations and requirements for sustainable homes.  These require that the light bulbs achieve higher efficiencies than traditional incandescent and halogen light bulbs. Initially we developed our L1 cap to meet the requirements of new building regulations related to energy savings. 

The GU10 lamp holder is one of the safest on the market and much safer than the B22 or E27 standard lamp holders.  We took the GU10 and added a pin to the lamp holder and a hold in the lamp cap.  This allowed our lamps to be used in GU10 lamp holders, but only allows our new dedicated lamp to be fitted into our lamp L1 lamp holder ensuring that the fitting runs efficiently and economically.
We do not go out of our way to make it difficult for people to get replacements lamps or indeed exploit a monopoly on these items, we are simply trying to find the best solutions to allow us to design the best looking and most efficient LED light fittings.
