Going back to the 90’s they were around and did save energy but did have their technical problems. One of the main issues with the ?uorescent tube was the ?icker and the dependency on good electronic integration with the starter. There were certainly many tubes that used to just ?icker the whole time, become a nuisance and just end up being turned off. These days the technology has advanced considerably and often have integral starters especially in the CFL types which make far easier electrical installations as no external starter of high frequency control gear is needed. The 2D compact version of the CFL ( compact ?uorescent lamp) is also extremely popular these days.  The main uses of the 2D compact are within commercial applications where is is necessary to have a bright but compact lamp that will ?t into a light ?tting which can either be ceiling or wall mounted. As a consequence there are a whole range of different 2D compact lamp ?ttings available on the market

2. which are used extensively in car parks, warehouses, corridors in ?ats, hotel areas not exposed to customers, retail outlets, of?ce buildings  and the list goes on.  As these lamps are energy ef?cient saving around 80% in electricity compared to standard incandescent light bulbs then they have really taken over as the standard for this classi?cation of installations. Quite often these lamps are connected to PIR units so they just light on demand when somebody passes the senses which makes them ideal for corridors areas which are not continually used and it would not be economical to leave the lights on the whole time! Type of 2D Compacts and 2Pin / 4 Pin explained The 2D compacts come in 3 main sizes, the 16w, 28w and 38w lamps. The 16w is a small units around 135mm square  and the 28w and 38w are larger measuring about 200mm square. This means than the light output is very good for the size of lamp with the 38W typically producing 2900 lumens which means where space is a premium and there is no room for ?uorescent tubes the 2D compact is an ideal solution. The lamps come with 2 types of cap ?tting either the 2 pin 2D compact or the 4 pin 2D compact. The 2 pin has its own built in

3. starter and the 4 pin lamp is con?gured to use with external electronic control gear either of the standard or high frequency type. CLICK HERE TO BUY 2D CFL LIGHT Main Drawbacks of the Fluorescent 2D Compact and the advantages of the LED 2D Compact The 2D compact has 3 main drawbacks. Firstly if it is used with PIR units the constant switching on and of will shorten the lifespan of the lamps,  secondly if they are left on for long periods they do use a signi?cant amount of electricity and thirdly the lifespan is only typically 10000 hours. This is where the 2D LED comes into play, The 2D LED is far more ef?cient and only uses around 50% of the  electricity of the CFL 2D compact and the additionally the LED technology is far more suited to rapid switching and you will not see a reduction in life. Finally the typical life is around 35000 hours which is 4 years of continuous use as opposed to just over 1 year for the ?uorescent 2D compact. However, the 2D LED is considerably higher investment so it is worth doing a cost analysis. CLICK HERE TO BUY 2D CFL LIGHT

Is there a starter or fuse in the actual unit that i need to check. if so where is it? Its a 2D 4pin Pl Bulb REPLY  admin 10TH SEPTEMBER 2014 AT 8:13 AM Hi Derek A 2D LED or 2D PL lamp has the driver built into the actual bulb. This means that if you are ?tting into an existing ?tting you need to bi-pass the ballast. REPLY John Moxey 5TH MARCH 2015 AT 4:52 PM My electrician ?tted 4 pin c? lights with no visible starter ,when I had to ?t a new lamp it would not work. It would appear that the units have an internal starter.What do you think is wrong.? REPLY  admin

5. 20TH MARCH 2015 AT 6:25 PM The CFL 4 pin has a ballast which need to be in the ?tting. Maybe this was not ?tted! If there is no ballast then you could use an LED lamp which does not need any ballast at all as you simply wire it straight across the mains. REPLY Dane McGill 21ST NOVEMBER 2014 AT 12:50 PM I have ?tted the correct 4 pin 2D bulb but having no joy. The ends of the bulb nearest the ?tting are glowing slightly but not coming on. What do I need to do? I’m a complete beginner when it comes to electrics so no industry speak please. Thanks REPLY  admin 21ST NOVEMBER 2014 AT 1:03 PM Hi Dane these PL lamps just need pushing in so they are easy to ?t. This sounds like it could be one of 2 problems as the correct power is not getting to all the 4 wires to the tube. Either the ballast, lamp holder or bulb is faulty. Best thing is to try a bulb you know works in this light and then you will know if it is the bulb or the ballast and then replace the failed part. Regards Paul SLB REPLY Dane McGill 21ST NOVEMBER 2014 AT 1:13 PM Ok thanks. De?nitely not the bulb so must be the ballast I suppose. Where the hell do I get me one of those? REPLY
