LAP GU5.3 MR16 LED Light Bulb 345lm 5W 5 Pack (2730V)

Hello Rachel101, Yes, this can be used above a shower. Thank you for using Q&A

I asked this question some weeks ago, but did not receive any replies, so I did my own research. These LEDs are fitted with an internal bridge rectifier so that they will work off 11.5v AC electronic transformers (as well as DC). They do not need expensive DC LED drivers. If replacing existing 12v halogen lamps with LEDs try one first and check that it works OK (some electronic transformers have a minimum load).

Hello, Are you using a suitable switch (ie not a dimmer etc). Unfortunately Screwfix does now have an electrical technical service, so we are limited in the troubleshooting assistance and advice we are able to give. The bulbs are 5 w each, and each driver is 25w, so your on the cusp of the max wattage. Have you tried removing 1 bulb from each driver to see if this stops the pulsing? If it does then it may be the driver is being overloaded. Is the driver your using LED compatible? If your using a halogen driver this may cause pulsing. You may wish to contact a competent tradesperson for further advice on this issue. Thanks for using Q&A

Hello These light are designed to be supplied by a constant voltage led driver 12VDC Please do not use it with electronic transfomer but 12VDC Power Supply ,so we do not think they will be suitable Thanks using Q&A

Hello Kayzz, Yes, if you are replacing halogen bulbs with LEDs, you will need to swap your transformers for LED drivers, such as the Aurora 12-240V Constant Voltage LED Driver 16W (2107T) or Aurora 12-240V Constant Voltage LED Driver 25W (4338T), depending on the total load/wattage. Thank you for using Screwfix Q&A.
