Poor Quality Day Light Bulbs - not meeting promoted lifespan

Day Light Bulbs ( Come on when light is restricted) I bought about 6 of these daylight type bulbs in May very expensive normal globes are R30 these are over R100

3 months ago I took the first unit in and explained with the sample of the products that it was a substandard light and would not come close to the recommended life expectancy promoted

2 weeks later I took another 2 of 6 in for same reason

Now 6 months later all 6 have failed. I have every intention to report the product to the standards association for this affiliation so that your products are under supervision by them
