Much more direct light source than the old style GU10. Warm tones from the LED's.

Used on a time switch to illuminate my garden pond. Give a very good light that is not too bright or harsh. I am very pleased with them

These guys deserve a review just because of how expertly packaged they sent my fragile and delicate T5 tubes. I will admit not having high hopes of a courier being able to deliver these in one piece but they were snugly bubble wrapped in a very sturdy cardboard tube. Fantastic fast delivery.

BLT suggested an alternative light bulb for one that had been discontinued which meant I didn't have to replace the fitting, very helpful, thanks
