This is the single ended version of the lamp above.

There are only two base types available, which makes it easier to pick the right one!

There are still 4 colour temperatures (k), but a couple more wattages!

We are not aquarium or vivarium experts but we know a good lighting product when we see one!

These are quality lamps made by BLV probably the best manufacturer in the world of this type of lamp.

There are 4 colour temperatures available, 5200k, 10,000k, 14,000k and 20,000k

If you are replacing like for like no problem, but as these lamps require control gear to make them work you can only change the colour temperature not the wattage.

If you do think you need to change the colour temperature of your lamp ask an expert on the animal you are keeping before ordering, we don't want anyone harming their pets with our products! Please be carefull!

These lamps have an average life of 6,000 hours, even so there is a strong consensus of opinion that a spare lamp is a very good idea just in case!

If you are not sure of the base you have give us a call or e-mail a picture of the lamp you have.

The G12 base is simply two pins 12mm apart, the E40 base is sometimes called a GES or Giant Screw. It measures 40mm across the threads.

We have more lamps available from other manufactures so if your is not on our list get in touch and we will try to help.

The control gear for metal halide lamps is a mystery to most people! If your gear fails we may well be able to help, we can repair the the gear if you can get it to us or provide you with replacement parts. We recommend you use an electrican to carry out repairs to tank lights, there are very high voltages involved and it is not worth the risk!
