Fern Howard LED 2D 4 Pin Lamp 11W 1000lm is rated 4.0 out of 5 by 8.
Rated 1 out of 5 by from Poor Service Terribly disappointed at the service at Poole When I collected my item, I checked it at the store. It was the wrong size and I was told that I could not return or exchange the item there and then. I need some now to tell me when I can return the item. Thankyou

Rated 5 out of 5 by from Wow brilliant! Replaced the CFL versions which kept going pop after a few months each. Straight swap and brighter in my opinion than equivalent CFL versions. Should last a lot longer. Well worth the price!

Rated 5 out of 5 by from Straight swap This was a straight swap for the old 16w fluorescent 2D bulb although it is definitely brighter. The colour temperature is stated so I was expecting ordinary white but it would be nice to have a choice of warm white.

Rated 5 out of 5 by from Great LED replacement I bought 5 of these lamps for our village hall. Simple to install and much better than the original CFL. They worked fine with the current Phillips ballast.

Rated 5 out of 5 by from Very Bright Bought this bulb to replace standard bulb that was getting temperamental. Very pleased with the brightness, ideal for a small bathroom. Instant full brightness with no flickering. Hope it stands up to the test of time.

Rated 1 out of 5 by from Would not work with Phillips HF ballast Infortunately this lamp did not work with my Phillips HF ballast. In response to question to Fern Howard they referred me to thier disclaimer which amonong other things says " It is the customer’s responsibility to validate that any non Fern-Howard product is suitable for use with the Fern-Howard 2D LED lamp. " The rating I have had to give it is based purely on the fact that it did not work with my NON Fern Howard light unit. In other lights it might be amazing, but be aware that it is not a global replacement even when used with an good quality ballast unit.

Rated 5 out of 5 by from Fern Howard 16W 2D LED lamp I bought 30 of these to replace 28W 2D tubes in the hallways of our flats. I thoroughly recommend them, easy to fit as they simply plug in to replace fluorescent lamps, and are much brighter (even though they are 1600 lumens which should be lower than the 2000 of a standard GR10q tube), also the colour of the light is better, flicker free, saving energy and hopefully not needing regular replacement as was the case with fluorescent lighting

Rated 5 out of 5 by from Great replacement for Fluro Don't normally review boring things like this, but I bought the led 16w version of this 4pin light to replace a flickering, temperamental fluorescent one. It is great, as bright as a 38w regular fluro bulb, if not brighter, a nicer light and comes on almost instantly to full brightness, rather than heating-up to full brightness. It was about 3x more expensive than a fluro, but will last longer, use less power and not get dangerously hot. Win win
