The four candles I want to mention come from IKEA in a pack labelled Hemsjo. (The O should have an umlaut above it.) All four cost me a modest £1.75. Each candle is 5.7 centimetres (57 millimetres) in diameter and stands 8 centimetres (80 millimetres) high, including the conical top. They are all unscented and white. An individual candle is rated at 15 hours of (continuous?) burning, so the whole pack should be good for at least 60 hours when lit consecutively. On a price per candle basis, they appear to be the cheapest pillar candle (IKEA calls them block candles) in their range, working out at £0.44 each.
As budget pillar candles, how do they perform? Well, as you might expect from the price, they need a little bit of effort to get the best out of them. I have found that they are definitely not light and forget, as this results in an excessive candle flame and a tendency to burn down too quickly ("funnel"). I would say that they are slightly under-wicked -- but it is safer to have them under- rather than over-wicked. With a little care you should certainly be able to exceed the stated burn time.
Going on the 30 minutes of burning per centimetre of diameter rule-of-thumb, and rounding up, this gives a single lighting duration of near enough three hours. I always trim the wick before starting, and Hemsjo seems to work best when I start with the wick at 3 millimetres (1/8 inch). (From experience, it is a bit of an art to set the starting wick length based on both the thickness of the wick and the diameter of the candle: it is usually somewhere between 3 and 6 millimetres on most household candles!)
Although it looks aesthetically pleasing, the conical top makes initial lighting a little more challenging. Due to the slope, the candle burns down quickly, resulting in a long wick that consumes wax at a faster rate -- and then it starts to funnel! When starting a new candle, I have tried limiting the first burn to one hour, but even this proved to be too long. I shall try 30 minutes next time! (A more drastic solution might be to slice the conical top off?)The wick is not anchored to the base of the candle in any way. (Some more expensive candles sometimes have a metal tag attached to the end of the wick.) What I have discovered is that further down the wick is markedly off-centre, and eventually it will collapse and drown in the melt pool. This is a good thing (safety again), but it does mean that the last centimetre or so of candle won't be consumed.
Unscented candles normally have no noticeable smell to me, but I have sometimes detected a faint paraffin odour after burning a Hemsjo candle for three hours. I don't find it offensive but I thought I should note it. I suspect it is down to the price: you get what you pay for, and all that...
Otherwise, I think that the IKEA Hemsjo candle is good value, and with a little attention burns reliably and with few surprises. This must be true: I have bought four packs so far and have already started on my second. Now if only they sold them in red for Christmas...
