"These lamps are well made but badly designed. The low height makes them advantageous and the clips hold them firmly in place.
The significant negatives are that the lamps are fitted by attaching a sucker to them, inserting in the fitting, fiddling with finding the locating holes and then twisting to retain. However, the sucker eventually falls off and you have to start again. The description says the lamps are 4000 hour ones and those supplied are only 2500! Probably not helped by the lip round the edge of the lamp interfering with the sucker. I aslo fear that time and heat may take the temper out of the spring clip holding the bezel in. Fear I'll be called back to that one for years to come!"
